Features and benefits

• 16 independently configurable channels supporting:

• 4 to 20 mADC or 1 to +5 VDC

• Up to 24 HART v5.4 secondary variables Total

• Max 4 sec vars per analog input CH

• Sec HART variables available to control logic

• 12 to 16-Bit (with polarity) A/D resolutionV

• A/D update of all 16 Channels in 100 msecs

• Accuracy is ±0.1 % of Full Scale Range where FSR = 25 mA or 6.25 VDC

The RAO02 module has one D/A converter for each output channel.

In current mode, the RAO02 module supports HART v5.4 instruments and

provides short circuit protection by limiting current to a maximum of 26 mA.

The RAO02 module will also detect an open circuit in less than 5 seconds.

The RAO02 Redundant Analog Output module processes up to 16 high-level,

group isolated, analog output field signals.

Each channel is independently configurable for either 4 to 20 mA or 1 to +5 VDC ranges.

FC 221 (I/O Device Definition) sets AO module operating parameters and

each output channel is configured using FC 223 (Analog Output CH) to

set indivdual output channel parameters such as engineering units,

High/Low Alarm limits, default value in event of loss of communication with controller, etc.

D/A resolution of each channel is 12 bits.

The RAO02 module has one D/A converter for each output channel.

In current mode, the RAO02 module supports HART v5.4 instruments and

provides short circuit protection by limiting current to a maximum of 26 mA.

The RAO02 module will also detect an open circuit in less than 5 seconds.

S800 I/O is a comprehensive, distributed and modular process I/O system 

that communicates with parent controllers and PLCs over industry-standard field buses.

The TB820V2 ModuleBus Modem is a fiber optic interface to the ModuleBus.

The ModuleBus Modem has an electric and an optical interface which are logically the same bus.

A maximum of 12 I/O modules can be connected to the electrical ModuleBus

and up to seven clusters can be connected to the fiber optic ModuleBus.

The fiber optic interface is intended for local distribution of I/O clusters

and where more than 12I/O modules are required in an I/O station.

Features and benefits

• 2 fiber optic ports to optical ModuleBus

• ModuleBus (electrical) to the I/O Modules

• Supervisory functions of I/O ModuleBus and power supply

• Isolated power supply to I/O modules

• TB820/TB820V2 has a rotary switch that selects its cluster number, 1 to 7. on the optical ModuleBus

The TU810/TU810V1 is a 16 channel 50 V compact module

termination unit (MTU) for the S800 I/O. The MTU is a passive unit

used for connection of the field wiring to the I/O modules. It also

contains a part of the ModuleBus.

The MTU distributes the ModuleBus to the I/O module and to the

next MTU. It also generates the correct address to the I/O module

by shifting the outgoing position signals to the next MTU.

Two mechanical keys are used to configure the MTU for different

types of I/O modules. This is only a mechanical configuration and

it does not affect the functionality of the MTU or the I/O module.

Each key has six positions, which gives a total number of 36

different configurations.

Features and benefits

• Compact installation of I/O modules using one-wire connections.

• Up to 16 channels of field signals and process power connections.

• Connections to ModuleBus and I/O modules.

• Mechanical keying prevents insertion of the wrong I/O module.

• Latching device to DIN rail for grounding.

• DIN rail mounting.
