About the Allen-Bradley 1734-OE4C

The 1734-OE4C is a POINT I/O 24V DC 4 point analog current output module. Its four single-ended, non-isolated outputs are configurable for 4…20 mA or 0…20 mA, with 16-bit resolution and a step response to 63% of full scale of 160 µs. It is factory calibrated and mounts on DIN rail on a 1734-TB, 1734-TBS, 1734-TB3, 1734-TB3S, 1734-TOP, 1734-TOPS, 1734-TOP3 or 1734-TOP3S terminal base.

What is the 1734-OE4C used for?

It sends four analog current signals to valves, drives and other field devices. Outputs stay at 0 mA until communication is established, and data is in signed integer format. It draws 75 mA at 5V DC from the POINTBus and 110 mA at 24V DC from field power, nominal, with outputs at 20 mA.
