Many procurement teams check CJ1G-CPU42H against Siemens PLC, Omron SMPS 24V 10A and Nx1P2 1040Dt1 before signing purchase orders, verifying quality, compliance, and after-sales support availability.
Omron CJ1G-CPU42H Programmable Logic Controller
The Omron CJ1G-CPU42H Programmable Logic Controller (PLC) is a compact and efficient CPU Unit designed for mid-level sequence control. It supports up to 960 I/O points with 30 Units across 2 expansion racks, making it suitable for modular machines and process equipment. With a 10K-step program capacity and 64K words of data memory (DM: 32K words, EM: 32K words Γ 1 bank), it handles essential logic and data operations reliably. A fast 0.04 ΞΌs LD instruction execution time ensures responsive performance, while the 0.91 A at 5 V consumption supports stable operation. Manufactured by Omron, part of the Omron Programmable Logic Controller range within the Omron CJ1 Series.
