Omron Omron CQM1H / CPM / CJ1M
Discontinued Discontinued 2015 · Manufacturer successor: CJ2M / CP1E / CP2E
Omron's CQM1H, CPM1A/CPM2A and CJ1M controllers cover compact machine control from small stand-alone PLCs to modular systems. Many remain in service in OEM machines. Omron has named replacement ranges, but these usually need program conversion.
What to check before ordering
- Full model number including supply voltage and output type
- CPU or unit version, and any memory cassette or battery
- Whether the machine program is backed up, as a replacement may need it loaded
- Special I/O or communication units attached
