T8403 Digital input module
Description
The Trusted TMR 24V dc digital input module interfaces to 40 field input devices. A wide input voltage range and programmable thresholds allow the module to be used in current source and current sink configurations. Comprehensive diagnostic tests are performed on each input channel, including tests for stuck on and stuck off failures. Fault tolerance is achieved through Triple Modular Redundancy (TMR) within the same module for each of the 40 input channels.
When a line-monitoring device is installed at the field switch, the module can ***ect open and shorted field cables. Line monitoring can be independently configured for each input channel.
The module provides on-board sequence of events (SOE) reporting with a resolution of 1ms. A change of state triggers an SOE entry. States are ***ermined by programmable voltage thresholds that can be configured on a per channel basis. When the field voltage and field return are connected to the auxiliary input channels of the module, thresholds can be specified as a ratio of the current field supply voltage.
Modules may be placed in any I/O module slot in a Trusted processor chassis or expander chassis. Once the I/O module configuration is set, mechanical keying is available on all I/O modules to prevent inserting a module into an incorrect slot.
Configuration of the module is carried out using the Trusted Toolset running on an engineering workstation. Once configured and loaded into the Trusted controller, replacement modules are online educated by the TMR processor.
