Integrator's note: 24 VDC relay PLC with expansion headroom
The CP1E-N30DR-D is a 24 VDC-powered PLC with 18 digital inputs and 12 relay outputs, part of Omron's CP1E series. It runs on CX-One software and carries 8K Words of memory, expandable up to 40 modules across 3 racks — enough for a medium-sized machine cell or a small line section. The relay outputs handle AC or DC loads up to the relay rating, making it a flexible choice for mixed-load panels. Communications are via RS-232C as standard, with option card slots available for adding fieldbus or serial expansion. The unit has no display, so all configuration and monitoring go through CX-One over the serial link.
The CP1E-N30DR-D carries CE, cULus, Lloyd, and NK approvals, covering European, North American, and marine (Lloyd's, Nippon Kaiji Kyokai) applications. This means the unit is accepted for use in industrial machinery, shipboard systems, and general control panels requiring those certifications. No RoHS or REACH statement is in the evidence, but Omron typically provides those on request for the CP1E series.
