GE IS220PTCCHA1A | Thermocouple input module

Description

GE IS220PTCCHA1A thermocouple input module designed for its Mark VIe series turbine control system
Function and purpose: It is mainly used to convert the temperature signals collected by thermocouple sensors into digital signals and transmit them to the control system for processing and analysis, so as to provide accurate data support for turbine temperature monitoring and control. It can be used for simplex, duplex and the third mock examination redundancy applications.
Hardware composition: Internally equipped with BPPx processor board and acquisition board for thermocouple input function. Receive input through dual RJ45 Ethernet connectors and three pin power input, and connect to the corresponding terminal board for output through a DC-37 pin connector. The front panel has indicator lights for visual diagnosis, and local diagnostic serial communication can also be performed through the infrared port.
Electrical characteristics:
Input channels: 12 thermocouple input channels, supporting E, J, K, S, T standard thermocouples and millivolt inputs ranging from -8 to 45mV.
A/D converter: 16 bits, capable of accurately converting analog signals into digital signals.
Common mode voltage: ± 5 volts, AC common mode rejection ratio of 100dB at 50/60Hz, with strong anti-interference ability.
Norm suppression: 250mV rms (± 5%) at 50/60Hz.
High and low hardware and software restriction check: With this function, it can ensure that the input signal is within the normal range and prevent abnormal signals from affecting the system.
Working environment: The working temperature range is -30 ℃ to 65 ℃, which can adapt to a wide range of industrial temperature changes.
Other features:
· Equipped with a high-speed processor, RAM, and flash memory, it can quickly process data and store relevant information.
· There are two completely independent 10/100 Ethernet ports for easy communication and data transmission with other devices.
· Equipped with hardware watchdog timer and reset circuit, it can improve the stability and reliability of the system.
· There is a local environmental temperature sensor that can monitor the temperature of the module’s own environment in real time.
· Having an electronic ID and the ability to read IDs on other boards, it facilitates the system’s identification and management of each module.
· Support advanced programmable logic for the acquisition board, which can be flexibly configured and expanded according to actual needs.
· The input power connector is equipped with a soft start/current limiter to protect the module from power surges.
· The local power supply has sorting and monitoring functions to ensure stable power supply and normal system operation.
