T9481/2 Analogue Output Module

The T9481 and 9482 analogue output modules are compact

and versatile modules that provide 4 – 20mA output current

for field devices.

Each channel is a current sink device and in simplex mode a

channel drops the full demanded current. In dual module

operation each channel drops half the output current.

The module features voltage and load current channel

monitoring, reverse current protection and short and open

circuit line monitoring. It is designed to always be able to

switch off an output when demanded.

Internal diagnostics carry out continuous functionality checks.

All module, channel and status information is displayed on front

panel indicators and status data is routed to the AADvance

where it can be viewed and checked.

The module has a user configurable failure mode that can be

set outputs to hold last state, fail safe, or a user defined output

state.

In dual mode both modules communicate with each other by

an inter-module link to maintain fault tolerant operation

Features:

 Supports 3 or 8 field devices

 Secure communication

 Suitable for safety and non-safety applications

 Operates in a single or dual redundant module

configuration

 Current sink device

 Supports transmission and receipt of HART messages
