Omron
Compact PLC CPU unit from the CPM1A series designed for discrete control in industrial automation. This model provides 40 total I/O with 24 digital inputs and 16 relay outputs, suitable for interfacing with 24 VDC input signals and switching AC loads up to 240 VAC via onboard relays. It supports 100–240 VAC supply for flexible installation in legacy panels and DIN rail mounting, offering straightforward deployment in machinery and small process systems. The unit’s relay outputs are ideal where isolation and AC load control are required, while the DC input circuitry accommodates standard sensor and pushbutton interfaces. Typical applications include machine sequencing, interlocking, and basic timing/logical functions. Package includes the CPU unit only; expansion options are available separately within the CPM1A ecosystem. This controller is a proven, durable platform for maintaining or retrofitting installed equipment that relies on CPM1A architecture.
