Many procurement teams check NX-OC2633 against Siemens PLC, Omron SMPS 24V 10A and Nx1P2 1040Dt1 before signing purchase orders, verifying quality, compliance, and after-sales support availability.
Omron NX-OC2633 Machine Automation Controller
The Omron NX-OC2633 Machine Automation Controller is a durable relay-based Communications Interface Unit offering 2 output points, designed for switching 250 VAC / 2 A and 24 VDC / 2 A loads with high reliability. It uses a Free-Run refreshing method and provides a consistent 15 ms ON/OFF response, making it suitable for electrical load isolation, contact switching, and panel-level safety control. Powered by 24 VDC with 5.80 W max consumption, it ensures dependable relay operation in industrial environments. Manufactured by Omron, part of the Omron Programmable Logic Controller (PLC) series under the Omron NX Series.
