TS800 receives 4-20mA input signal of the control room, micro-processor (CPU) compares
input signal with position feedback through potentiometer and sends control signal to I/P
conversion module torque motor, torque motor converts it to a pneumatic signal to controls
pilot valve to controls the opening of the control valve by converting output pressure of OUT1
and OUT2.
