-
Product Description: An analog input termination board used in Mark V Series control systems to condition low-level signals from field sensors before passing them to the controller.
-
Technical Specifications: Six differential input channels. Supports 4-20 mA, 0-10 VDC, thermocouples (Type J, K, T), and RTDs. Input impedance > 250 kΩ.
Detailed content
-
Working Principle: Signals pass through precision instrumentation amplifiers and passive RC filters to remove line noise. Cold junction compensation is provided for thermocouple inputs.
-
Structural Features: Modular design with pluggable screw terminals for easy wiring. Includes on-board lightning arrestors and fuse protection for each channel.
-
Application Scenarios: Essential for temperature monitoring in gas turbine exhausts, bearing temperature sensing, and pressure transducer interfacing.
-
Installation Requirements: Requires shielded twisted-pair cabling for analog signals. Grounding must follow GE’s single-point grounding scheme to prevent ground loops.
