Description
🔧 Product Description
The GE General Electric IS220PRTDH1A is a Resistance Temperature Device (RTD) Input/Output Pack designed for the GE Mark VIe distributed I/O system. It receives temperature signals from RTD sensors, converts the resistance measurements into digital data, and communicates the information to the Mark VIe controller through the I/O Ethernet network. The pack supports up to 8 RTD input channels and connects to compatible TRTD or SRTD terminal boards through a DC-37 connector. It also provides two RJ45 Ethernet ports, a dedicated power input, and front-panel diagnostic indicators.
