HE693THM884M

GE HE693THM884M is a thermocouple input module, belongs to GE Fanuc series products, commonly used in industrial automation control system temperature signal acquisition and processing.

Function: It can connect the thermocouple temperature sensor to PLC directly without using external signal processing equipment such as transmitter, and the module can process the thermocouple signals in analog and digital.

Main parameters: operating voltage of 5V DC, power consumption of 100mA, with 8 thermocouple channels, input impedance of 20MΩ, support for J, K-type thermocouples. Scanning rate is 40 channels per second with resolution up to 0.1°C. Temperature values can be reported to the PLC’s I/O table in increments of 0.5°C, 0.5°F, 0.1°C or 0.1°F.

Alarm Function: Equipped with 16 alarm bits, each channel has one open circuit alarm and one set point alarm, the alarm set point can be set individually for each channel through 8 analog output (%AQ) registers.

Installation: Supports compact rail mounting and traditional panel mounting. For panel mounting, the mounting hole positions are the same as those of the previous four-hole mounted 3300 preamplifier.

Application areas: It can be applied in electric power, chemical industry, metallurgy and other industrial fields that require temperature measurement and control, such as in the control system of the combustion engine, to accurately measure and monitor the relevant temperature points of the gas turbine, and provide accurate temperature data for the control system, so as to realize the accurate control and protection of the operating status of the combustion engine.
