DescriptionMoog N121001A Servo Controller. Dual Transducer | 4 to 20 mA Output | 1.0 to 47 mA/V Proportional Gain
DescriptionMoog N121-001A Series Dual Transducer Servocontrollers
OverviewThe N121-001A Series Dual Transducer Servocontroller was developed specifically for General Electric gas and steam turbine upgrades and modifications.This circuit card is designed to interface with various manufacturers’ turbine controlllers, existing or new intrinsically safe servovalves and redundant position feedback transducers. Specifically, the N121-001A contains current drivers for driving triple redundant servovalve coils, redundant excitation/demodulation circuits for dual position feedback transducers, a comparator high select circuit, and 4 to 20 mA interface circuits.
Key FeaturesClosed-loop control of redundant linear transducer position loops. PID control; jumper selectable with independent gain potentiometers. Linear transducer signal high selection circuit. Current limiter (rate limit control possible). 4 to 20 mA input for position command signal. 4 to 20 mA outputs to monitor the position feedback signals. SPDT relay section - jumper selectable Hi (+5 to 15 VDC) or Low (0 VDC) activation logic state
