GE IS220PRTDH1B RTD Temperature Input I/O Pack in stock

GE IS220PRTDH1B is a dedicated RTD input I/O pack for GE Speedtronic Mark VIe and Mark VIeS turbine control systems. It works with TRTD terminal boards to collect resistance signals from Pt100, Pt1000 and other RTD sensors, converting raw resistance data into digital temperature values and transmitting to the main controller via dual IONet Ethernet ports.

This pack supports 3-wire RTD connection, built-in high-precision signal conditioning and channel diagnostic function. It supports simplex and TMR redundant configurations, widely used for bearing temperature, stator winding temperature monitoring of gas turbines, steam turbines and generators, and is a common spare part for power plant Mark VIe cabinet maintenance.
