Fiber optic coupler for glass fiber optic cables with an emission wavelength of 820 nm Fiber optic connection with bayonet socket BFOC/2.5 (IEC-SC86B)

Optical isolation of the RTU560 bus

Suitable for use as star coupler for RS-485 and RS-232 buses

IEC 60870-5-103 device interface

Front panel connector for 2 optical lines

Fiber optic coupler 23OK24

The fiber optic coupler 23OK24 is suitable for the RTU560. the module is used to transmit data via 2 independent optical links (receive and transmit).

Fiber optic cables are insensitive to inductive and capacitive interference as well as to potential differences between the two data communication devices.

In critical environments or when potential isolation is required, fiber optic cables can be used to bridge across distances. With 200 μm fiber optic cables, the maximum distance is up to 2600 meters.

The module can be used to convert the receive and transmit data signals of the following electrical interface standards to fiber optic signals:

– RTU560 SPB I/O bus

– RS-485 bus

– RS-232 C

APPLICATIONS

The 23WT23 board is a modem that converts serial data according to the CCITT V.23 standard.

Therefore, it can be used for transmission over leased PTT lines, private networks or radios.

The two-wire or four-wire mode of operation can be selected via jumpers. The Voice Frequency (VF) output has a high impedance and can connect up to 10 remote stations to multiple pull-down lines.

The modem 23WT23 is available in two versions (rubrics):

– R0001: 5 VDC power supply

– R0002: 24 VDC power supply

Features

The 23WT23 circuit board is a printed circuit in Eurocard (160 mm x 100 mm) format.

All necessary configurations, such as transmit-output level, receiver sensitivity, and two- or four-wire operation, can be configured via jumpers.

The interface to the Data Terminal Equipment (DTE) operates according to the RS 232-C standard and provides the following signals:

– TxD Transmit Data

– RxD Receive Data

– RTS request to send

– DCD Data carrier detect

– CTS Clear to transmit

– DSR Data setup ready

The receiver level is monitored and the alarm relay, together with the light-emitting diode (LED) “ST”, indicates a longer (approx. 4-6 seconds) interruption of the carrier.

The LED on the front panel shows the signal status of the RS 232-C interface. The serial interface signals as well as the VFT line can be measured or opened using the disconnect test socket on the front panel.

APPLICATIONS

The Line Transformer 500LTD02 is designed to be used

for 9.6kBd FSK channels and to isolate and protect RTU500 series modems.

Isolates and protects RTU500 series modems

23WT24 and 560FSM11 Isolates and protects the RTU500 series modems from the remote control line.

Line isolation and protection. In addition, it can be connected to

other data terminal equipment. It operates over a frequency range of 2 kHz to 50 kHz.

Frequency range of 2 kHz to 50 kHz

The line impedance is 150 ohms and is suitable for the above modems.

Both types of modems are capable of high-resistance interleaving on party lines and multi-line circuits.

This is due to the fact that the line transformer has no additional load on the line.

In configurations using full duplex communication channels, two line transformers are required, one for the transmit direction and the other for the receive direction.

Features

The 23WT25 modem enables high-resistance interleaving on multidivision lines. No special additional provisions are required for duplex and half-duplex operation.

such as butterfly connections based on channel assignment and the selected two-wire or four-wire line. It is designed for the transmission characteristics of local cable lines.

Light-emitting diodes indicate the most important operating states, and disconnect test sockets on the front panel make it easy to test and measure VFT channels as well as Data Terminal Equipment (DTE) interface signals.

In the RTU560 subrack, the modem board occupies one slot. The modems are available in two different sizes for two different supply voltages.

In the RTU560 subrack, it is powered by 24 V DC (R0002). the R0002 (24 V DC) can also be used with a 24 V supply voltage with a voltage tolerance of ± 20 %.

Therefore, it can also be used outside the RTU 560. If only 5 V DC is available, the R0001 standard is used.

The digital signal processor (DSP) is responsible for converting binary information into speech bands and vice versa.

Among other things, its high processing power enables highly selective channel filtering (90 dB) and thus unlimited channel assignment.

Applications

The RTU component 560NUS04 is an unmanaged plug-and-play 10/100 Mbps Ethernet switch providing four Fast Ethernet auto-negotiation RJ45 ports.

It features automatic MDI/X (automatic crossover detection and correction). The switch is used to distribute Ethernet within the station and to provide Ethernet for the local area network (LAN).

It provides additional ports for local area networks (LANs) and can be used with the rackmount 560MPR01. 560MPR03. and 560SFR02.

Features

For documentation purposes, Ethernet ports are labeled as

No specific uplink port; all ports function identically.

Status indicators show the link and speed status of each port (see “Connectors and Indicators”).

Status indicators show link and speed status for each port (see Connectors and Indicators).

The switch learns the Ethernet address by analyzing received frames.

The frames are analyzed to learn the Ethernet address. The learned addresses are stored in a lookup table (up to 1024

entries), which is used to forward frames only to the correct port.A

received frame is forwarded to all ports, but the receiving port

forwards to all ports if it is broadcast or multicast or if the destination address is not found in the lookup table.

The destination address is not found in the lookup table. If an entry in the lookup table is not refreshed by an incoming frame with a specific source

the entry in the lookup table is not refreshed by incoming frames with a specific source, it is aged out for up to 300 seconds.
