The 6331A is a two-wire programmable transmitter designed for linearized temperature measurement with RTD or thermocouple sensors, conversion of resistance variation to a 4...20 mA signal, or amplification of bipolar mV signals. It mounts on a DIN rail in a housing measuring 109 x 23.5 x 104 mm and supports 1- or 2-channel configurations. The device features 1.5 kVAC galvanic isolation between input and output, and 3.75 kVAC isolation between channels in dual-unit versions. It operates from 7.2 to 35 VDC, with a minimum voltage drop of 7.2 VDC, and accepts RTD, thermocouple, resistance, or mV inputs. Output range is 4...20 mA with a maximum load of (Vsupply - 7.2) / 0.023 ohms. The transmitter complies with EMC Directive 2004/108/EC and EN 61326-1, has IP20 protection, and supports programmable sensor error detection per NAMUR NE43 with upscale at 23 mA and downscale at 3.5 mA.
