GE IS200VRTDH1D RTD Input Board

Feature & Principle

It is a dedicated RTD temperature acquisition board for GE Speedtronic Mark VI VME rack. It supplies excitation current to 3-wire RTD sensors such as Pt100, samples resistance value and converts into digital temperature value, then transmits data to main controller via backplane bus. It supports multi-point temperature monitoring for turbine bearing, generator winding and oil temperature. With built-in open/short circuit diagnosis for sensor loop. Conformal coating protects circuit from moisture and corrosive gas in power plant cabinet.
