Product Description

Speedtronic Mark V EE Prom Board DS200DSPDF1A was produced by General Electric to work in steam and gas turbine control systems. This board will typically be used in TMR (Triple Modular Redundant) or Simplex applications. There are built-in diagnostics which include background, power-up, and diagnostic routines that are manually initiated. The diagnostic routines have the ability to identify sensor, output device, and control panel faults; all of the faults can be identified directly down to the board level for the circuit level for actuator and sensor components. One feature of this board is that it can be replaced online when used in a triple redundant design. 

There are hardware inputs and outputs on the DS200DSPDF1A board, the inputs on this board are contact, analog, and pulse rate inputs, while the outputs are analog, solenoid, and contact outputs. The pulse rate inputs of this board have sensors that fall into three categories, sensors that feed <P>, TTL type inputs that will feed <R>, <S>, and <T>, as well as sensors that feed <R>, <S>, and <T>; when being used in simplex applications the latter sensor will only feed the <R> sensor.
