RS-485 repeater D6212Q

interfacecurrent

The Repeater Power Supply D6212 module is a high integrity analog input interface suitable for applications requiring SIL 2 level in safety related systems for high risk industries. It provides a fully floating dc supply for energizing conventional 2 wires 0/4-20 mA, active or passive, transmitters, and repeats the current in floating circuit. The module is fully configurable to achieve input/output multiplexing, scaling, duplication, inversion, and input elaboration (addition, subtraction, low/high selection). An additional alarm contact can be (de-)activated on programmable input trip points, including hysteresis and delays. Configuration and diagnostic parameters are programmable and can also be monitored/set through Modbus. FEATURES SIL 2 / SC 3 0/4-20 mA Active-Passive Input, Source Output Duplication/inversion/scaling output Input operations (sum, dif, max, min) available Input and Output short circuit proof Out of range fault detection Alarm output with user-settable trip points Modbus RTU RS-485 for monitor & configuration Fully programmable operating parameters High Accuracy, µP controlled A/D converter Three port isolation, Input / Output / Supply High Density, four channels per unit
