ORDERING INFORMATION
D6254S: 1 channel Accessories Bus Connector JDFT050, Bus Mounting Kit OPT5096. Programmable USB serial line Kit PPC5092 + SWC5090. TECHNICAL DATA SIL 2 / SC 3 ±12 V Voltage Input 0/4-20 mA Active-Passive Input, Source-Sink Output Input and Output short circuit proof Modbus RTU RS-485 for monitor & configuration 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 The 2/4-Wire Transmitter Trip Amplifier D6254 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. The module repeats/converts the input as on current signal, in a floating circuit, 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.
