Signal amplifier D5254S

currentvoltageisolation

The 2/4-Wire Transmitter Trip Amplifier D5254 provides a fully floating dc supply to energize conventional 2 wires 4-20 mA transmitters located in Hazardous Area; it also accepts 0/4-20 mA current input signals, as well as ±12 V voltage inputs from Hazardous Area. The module repeats/converts the input as on current signal, in a floating circuit to drive a Safe Area load, suitable for applications requiring SIL 2 in safety related systems for high risk industries. The output signal can be in direct or reverse form. Two independent Alarm Trip Amplifiers are also provided. FEATURES SIL 2 / SC 3 Input from Zone 0/Div. 1 Installation in Zone 2/Div. 2 ±12 V Voltage Input Input and Output short circuit proof Out-of-range fault detection Optional alarm acknowledgement input Fully programmable operating parameters High Accuracy, μP controlled A/D converter Three port isolation, Input/Output/Supply
