Signal converter Sensor 4-20mA 1W-UNI, isolated, base unit without power adapter, 1-Wire UNI - HW group 600565

Pressure transmitters in cooling loops and level probes in tanks usually output a 4-20 mA signal. The Sensor 4-20mA 1W-UNI powers the current loop, isolates it from the bus and makes the reading available over 1-Wire UNI. According to the manufacturer, the loop can run for tens or even hundreds of meters.

Benefits

• Works with most industrial probes: 4-20 mA input for two-wire sink-type probes.
• Powers the probe: built-in current source, fed by an external 12-30 V DC supply.
• Isolated: current loop and 1-Wire UNI bus are separated, protected by a 63 mA fuse.
• Adjustable: 8-point calibration table, set with the 1W-UNI USB calibrator.
• Daisy-chain ready: 2x RJ11 for linking several sensors.

Applications

• Pressure transmitters in liquid cooling loops with CDUs and quick disconnects
• Level of coolant and fuel tanks, for example for backup generators
• CO2 and gas concentration in equipment rooms
• pH probes and other industrial sensors with a 4-20 mA output

Compatibility

• Connects to 1-Wire UNI RJ11 ports on Ares, STE2, Poseidon2 and SD 2x1Wire
• For self-powered 0-20 mA sensors, use the Sensor 0-20mA 1W-UNI
