ICS Triplex T8042 Digital Input module

Description

The Trusted® Dual 24 Vdc Digital Input Module interfaces to 60 field input devices. Fault tolerance is achieved through the ‘One-Out Of-Two D’ (1oo2D) voting architecture within the Module for each of the 60 input channels. Each field input is duplicated and the input voltages are measured using sigma-delta input circuits. The resulting field voltage measurement is compared to user configurable threshold voltages to determine the reported field input state. When a line-monitoring device is installed at the field switch, the Module can detect open and short circuit field cables. Line monitoring functions are independently configured for each input channel. The dual voltage measurement, coupled with onboard diagnostic testing, provides comprehensive fault detection and tolerance. The Module provides on-board Sequence of Events (SOE) reporting with a resolution of 1 ms. A change of state triggers an SOE entry. States are determined by voltage thresholds that can be configured on a per channel basis. Features: • 60 duplicated input channels per Module. • Comprehensive, automatic diagnostics and self-test. • Selectable line monitoring per channel to detect open circuit and short circuit field wiring faults. • 2500 V impulse withstand opto/galvanic isolation barrier. • On-board Sequence of Events (SOE) reporting with 1 ms resolution. • Configurable 50/60 Hz digital filtering to mitigate field induced noise. • Module can be hot-replaced on-line using dedicated Companion (adjacent) Slot or SmartSlot (one spare slot for many Modules) configurations.Front Panel Module status LEDs indicate Module health and operational mode (Active, Standby, Educated).

Common controllers in industrial control systems The Controller refers to the master command device that controls the starting, speed regulation, braking and reverse of the motor by changing the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order.  It is the "decision-making organization" that issues commands and completes the operation of coordinating and commanding the whole computer system. 1.  Programmable Logic Controller (PLC) is a special Controller, which is a digital computing electronic system designed for industrial applications. 2, Programmable Automation controller (PAC) is defined as: supported by a lightweight control engine, and use the same development tool for a variety of applications. 3.  The fundamental difference between PAC and PLC lies in their different foundations.  The performance of PLC depends on special hardware, and the execution of application program is realized by special hardware chip. 4.  Remote Terminal Unit (RTU) is the electronic equipment installed in the Remote site, which is used to monitor and control the status of sensors and equipment in the Remote site.  RTU is responsible for the monitoring and control of field signals and industrial equipment, obtaining equipment data, and sending the data to the dispatching center of SCADA system. 5.  In the remote measurement and control system, RTU is the key equipment to realize remote communication, which is responsible for the uploading and transmitting of information between the central station and the measurement station.  It mainly has four functions: remote communication, telemetry, remote control and remote modulation. ◆ Remote communication function: the passive contact mode is required, that is, the input of a certain distance communication amount should be a pair of relay contacts, or is closed, or is disconnected. ◆ Telemetry function: by collecting the signals of various sensors and transmitters to obtain the physical parameters of the scene, the collected variables are stored and encoded into telemetry information, which is transmitted to the monitoring center according to the communication protocol. ◆ Remote control function: the monitoring center implements remote control on the site equipment, such as starting or shutting down a device, opening or closing a valve. ◆ Remote adjustment function: the monitoring center can adjust the working status and parameters of some equipment in the controlled station.
