ICS Triplex T8431

ICS Triplex  T8431   Analog Input Module-40Channel

The TMR 24V dc analog input module, shown in Figure 6-2, interfaces to 40 sourcing field input devices. The module is designed to monitor input signals in the range 0-6V (0 to 24mA via a 250R resistor on the field termination assembly). The module acts as a current sink for the devices.

The module can detect open and shorted field cables using the built-in linemonitoring feature. Line monitoring functions are 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 (not an application logic action). States are determined by voltage thresholds that can be configured on a per channel basis.

Status LEDs

The input status LED mode is dependent upon the voltage level of the field I/O signal. Each field input voltage is measured and compared to six threshold levels (four configurable and two fixed) which produce seven threshold bands, as described in Section 10. Each threshold band can be defined to have a particular indicator mode: off, solid or flashing green, or solid or flashing red. One example of LED indications for analog inputs would be:

System Overview
TRUSTED programmable controller consists of three main parts: controller part, expander part, and power supply part. In the controller
There are various triple modules in the parts and extender sections.
All triple modular units are installed in a 19 inch rack. The installation bracket allows for front panel installation and rear panel installation.
The communication between TRUSTED system and external systems can be achieved through the main processor, dedicated communication module, or gateway module. Multiple communication protocols can be used for serial communication and Ethernet communication. The communication module can be installed in the control rack and expansion rack.
