ICS Triplex T9451 Digital Output Module

ICS Triplex T9451 Digital Output Module

The T9451 digital output module interfaces up to eight final elements and can switch 1A at 32V dc for each device. It features voltage and load current monitoring on each channel, reverse current protection and short and open circuit line monitoring. It is designed to always be able to switch off an output when demanded.No single failure within the module can cause a stuck-on failure. The module supports dual redundant power feeds for field devices without the need for external diodes.

The output module isolates the processor module from the output channel control and data management circuits, thus protecting the processor module from potential faults in the output control circuits and field connections.

The output channel protection activates when the channel load exceeds a safe limit. The reverse voltage protection circuit in each output channel ensures that externally applied voltages do not generate current flow into the module outputs.

The module has self-checking functionality. Short circuit and open circuit line monitoring is provided on all outputs. Internal diagnostics carry out ongoing functionality checks ensuring that the output channel command data is correctly transferred to the output. In addition, the processor module initiates a test sequence on each output channel, checking for 'stuck-on' and 'stuck-off' conditions on the output switch pairs.

Front panel LEDs provide module, channel and field connection status indications. These status indications can be connected to application variables and viewed at the Workbench.

When a controller uses a pair of digital output modules in a dual configuration, the two fail-safe output switches on each channel are combined in a parallel arrangement so that they automatically form a fault-tolerant output configuration.
