DS3820RTDB
RES TEMP DET
GE Speedtronic Mark IV DS3820RTDB is an RTD Input Module and functions as an RTD Board. Temperature is measured by RTDs, or resistance temperature detectors, which have a ceramic or glass core wrapped in fine wire and protected by an outer casing. This board is held in place by two downward flanges and one upward turned flange on a metal carrier. Each corner of the carrier is factory drilled and tagged with the board's id number. Two vertical pin connectors and a number of capacitors are included on the circuit board.
The RTD components are also included. The board surface has a waffle design printed on it and is drilled twice in each corner for mounting possibilities. The circuit board was connected to the carrier surface using four of these drill sites.
