This signal conditioner provides the isolation for non-intrinsically safe applications. The device drives a current signal from the control side to I/P converters, electrical valves and positioners. The max. voltage drop at the input is 4 V DC, allowing for the connection of several KFD2-CD-1.32 repeaters due to the low voltage drop in order to maintain multiple galvanically isolated outputs (signal duplication). The open circuit voltage is 24 V DC within the allowable supply voltage range. The maximum load that can be applied is 850 Ω.
