Product Overview

The Omron CJ1W-DA041 is a 4-channel analog output unit for the CJ-series PLC rack, used with CJ1, CJ1M, CJ2, and NJ-series CPUs that accept CJ1W expansion. It is manufactured by Omron Corporation. Hengyixin Automation stocks this I/O expansion unit in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports. Specifications on this page were checked against Omron's CJ-series Analog I/O Unit documentation.

FAQ for CJ1W-DA041

What happens to the analog outputs when the CPU stops?
By default, each output holds its last value (HOLD). The CJ1W-DA041 also supports CLR (output to 0 V or 0 mA) and MAX (output to full scale) as selectable behaviours. The mode is set per channel in the CPU memory and is useful for fail-safe valve positioning on a PLC fault.
Can I mix voltage and current outputs on the CJ1W-DA041?
Yes. Each of the four outputs has its own signal range setting in the CPU memory, so you can run two outputs at 4-20 mA and two at 0-10 V on the same module. Wiring differs per channel but the scaling is independent.
Is the CJ1W-DA041 compatible with a CJ2 CPU?
Yes. CJ1W I/O modules are supported on CJ1, CJ1M, CJ2, and NJ-series racks (with CJ1W adapter). The DA041 is registered as a special I/O unit in CX-Programmer or Sysmac Studio, and the binary output word is updated each PLC scan just like any CJ1W slice.
