Product Description
IS220PRTDH1B is an RTD resistance temperature input module for GE Speedtronic Mark VIe turbine control system. The module collects signals from platinum RTD sensors to monitor and protect temperature points of steam turbine, gas turbine bearings, lube oil, motor windings and other measuring points. It supports hot swap and built-in channel fault diagnosis. It can expand temperature measuring channels with TRTD terminal board. Equipped with dual I/O Ethernet ports to connect to Mark VIe control network, the module has galvanic isolation for stable and reliable operation. It is a core I/O spare part for power plant turbine control systems.
