AC Power Source Connections

The Hot, Neutral, and Ground wires from the

20 VAC power source or L1, L2. and

Ground wires from the 240 VAC power source connect to the system through the top three

terminals of the terminal strip on the front of the power supply.

DC Power Source Connections

Connect the + and – wires from the

25 VDC (nominal) power source to the top two

terminals on the terminal connector.  These connections are not polarity-sensitive on an

AC/DC input power supply.  (However, the DC Input-only type supplies, which are

discussed later in this chapter, are polarity sensitive.)

Input Overvoltage Protection Devices

This information applies to all Series 90-30 power supplies except IC693PWR322

and IC693PWR328.  The overvoltage protection devices for this power supply are

connected internally to pin 4 on the user terminal strip.  This pin is normally connected to

frame ground (pin 3) with the supplied jumper strap which is installed at the factory.  If

overvoltage protection is not required or is supplied upstream, this feature can be disabled

by  removing the jumper strap from pins 3 and 4.

Field Wiring Connections for the AC/DC Input Power Supplies

The two AC/DC input power supplies have six terminals for user connections.  These connections

are described below.

AC Power Source Connections

The Hot, Neutral, and Ground wires from the

20 VAC power source or L1, L2. and

Ground wires from the 240 VAC power source connect to the system through the top three

terminals of the terminal strip on the front of the power supply.

The IC693PWR330 High Capacity Power Supply is rated for 30 watts output.  For applications

requiring greater +5V current capacity than is available with the standard supply

(IC693PWR321), this supply allows all 30 watts to be consumed from the +5V supply.  It can

operate from an input voltage source in the range of 85 to 264 VAC or

100 to 300 VDC. This power  supply provides the following outputs:

• +5 VDC output.

• +24 VDC Relay power output which provides power to circuits on Series 90-30  Output Relay

modules.

• Isolated +24 VDC, which is used internally by some modules, can also be used to provide

external power for 24 VDC Input modules.

Output Data Transfer:

Data for each analog output

channel is written directly into an on-board register

location dedicated to a specific channel.  The data is

then periodically retrieved from the register, and

converted to an analog voltage which is transferred to

one of 32 output sample-and-hold buffers.

A/D Data Format (Built-in-Test Data):

Analog

inputs are first digitized, then the 12-bit digital values

(D11 to D00) are read at a single memory word location.

In two’s complement mode, the upper four bits (D15.

D14. D13. and D12) are read as the sign extension of the

12-bit digital value, otherwise they are read as logical zeros.

Built-in-Testing:

Built-in-Test logic provides the user

with the capability to test all of the active components on

the board, including the output switches. This test

scheme utilizes an on-board analog-to-digital converter

(ADC) and multiplexers, as shown in Figure 1.

Memory Testing:

This product is designed with

dual-port on-board registers that may be tested by

executing a user-defined memory test program for

additional performance verification.

System Reset:

Application of the system reset signal

via the VMEbus initializes the board into a state with all

analog outputs disconnected from the output.

FUNCTIONAL CHARACTERISTICS

VMEbus Compliance:

The analog output board is a

standard double height printed circuit board which is

compatible with the VMEbus specification (Rev. C.1).

VMEbus A16:D16

Board Address:

The physical address for the board

may be selected by on-board jumpers.  VMEbus address

lines A07 through A15 are decoded for board selection.

VMEbus Access:

Address modifier bits are

jumper-selected and decoded to support both

nonprivileged short I/O, supervisory short I/O, or both.

The board is factory-configured for supervisory short I/O.

Output Data Transfer:

Data for each analog output

channel is written directly into an on-board register

location dedicated to a specific channel.  The data is

then periodically retrieved from the register, and

converted to an analog voltage which is transferred to

one of 32 output sample-and-hold buffers.

48VDC 32 Point Positive/Negative Logic Input module, IC694MDL658. provides

32 discrete input points that operate at levels up to 60V.  Power to operate field

devices must be provided using an external supply.

The blue band on the front label indicates a low-voltage module.

These modules do not report special fault or alarm diagnostics.  Green LEDs

indicate the ON/OFF status of each input point.

These modules can be installed in any I/O slot in the RX3i system.

PACSystems RX3i 32-Point Positive/Negative Logic input modules provide 32

positive or negative logic input points in four isolated groups of eight. Each group is

referenced to its own common connection.

5/12VDC (TTL) 32 Point Positive/Negative Logic Input module, IC694MDL654.

shown at left,  provides 32 discrete TTL voltage threshold input points that operate

at levels up to 15V.  A single, regulated +5V supply (current limited to approximately

150mA) is available through the I/O connectors on the front of the module.  This

supply is generated on the module and is isolated from the backplane.  Its power

input comes from the +5V logic supply on the PLC backplane.  By installing jumpers

on the I/O connector, you can choose to power the inputs from this internal supply

instead of powering them with an external user provided supply.

24VDC 32 Point Positive/Negative Logic Input module, IC694MDL655. provides

32 discrete input points that operate at levels up to 30V.  Power to operate field

devices can come from an external supply or from the module’s isolated +24 VDC output.

The board accepts a 14-bit digital output

word (shaft angle), a reference excitation voltage, and

produces a synchro or resolver output.

The board is ideally suited for computer-based systems

in which digital information is processed, such as simulators,

robotics, and other control-oriented systems. The DSC/DRC

is provided with several options and is capable of interfacing

with most standard synchro or resolver devices.

The IC697CMM742 Ethernet Interface (Type 2)

provides high performance TCP/IP communications for the IC697 PLC.

The Ethernet Interface (Type 2) plugs into a single slot

in an IC697 PLC rack and is configured with the IC641

PLC programming software.  Up to four Ethernet

Interface (Type 2) modules can be installed in an IC697 PLC CPU rack.

The Ethernet Interface (Type 2) contains three network

ports: 10BaseT (RJ-45 connector), 10Base2 (BNC

connector), and AUI (15-pin D-connector).

The Ethernet Interface automatically selects the network

port in use.  One network port may be used at a time.

The 10BaseT network port permits direct connection to

a 10BaseT (twisted pair) network hub or repeater

without an external transceiver.

The 10Base2 network port permits direct connection to

a 10Base2 (ThinWire ) network without an external transceiver.

The AUI network port permits attachment of a user

supplied AUI (Attachment Unit Interface, or transceiver) cable.

The AUI cable connects the Ethernet Interface to a user-supplied transceiver

that is directly connected to the 10Mbps Ethernet network.

The transceiver must be 802.3 compatible and must have the SQE option enabled.
