LEICA 301-360.021 CH-A Power Supply Unit – Industrial Control System Power Module | SMC CJ1B4-10U4 Platform
Engineering Background
The LEICA 301-360.021 CH-A is a precision-engineered industrial power supply assembly designed for demanding automation and metrology environments. This unit integrates three (3×) 944AOPLPNCSTS sub-modules within a robust 400mm (L) × 190mm (W) chassis, providing stable, conditioned DC power to connected control hardware. The assembly is paired with an SMC CJ1B4-10U4 PLC power supply module—part of OMRON’s CJ-series programmable controller platform—making it a complete, field-ready power backbone for complex control architectures.
Product Positioning
Targeted at procurement engineers and MRO specialists sourcing verified surplus or replacement power assemblies for LEICA coordinate measurement systems, industrial metrology rigs, and CJ-series PLC control panels. This unit eliminates the lead-time risk of OEM procurement while maintaining full specification compliance.

Proven Application Environments
- LEICA coordinate measuring machine (CMM) power distribution systems
- OMRON CJ-series PLC control panels requiring dedicated power supply modules
- Industrial metrology and precision measurement automation lines
- Factory automation retrofit and MRO replacement projects
- Multi-axis motion control systems with CJ1B4-series backplane integration
Engineering Advantages
- Triple sub-module redundancy: 3× 944AOPLPNCSTS configuration distributes load and improves mean time between failures (MTBF)
- Compact form factor: 400×190mm chassis fits standard 19″ rack and DIN-rail enclosure footprints
- Cross-platform compatibility: SMC CJ1B4-10U4 pairing enables direct integration with OMRON CJ1/CJ2 PLC backplanes
- Verified surplus stock: Each unit inspected and function-tested prior to listing—no blind-ship refurbished units
- Immediate availability: Eliminates 8–20 week OEM lead times for discontinued or allocation-constrained assemblies
System Architecture & Signal Flow
The 301-360.021 CH-A assembly accepts primary AC input and conditions it through three parallel 944AOPLPNCSTS rectifier/regulator sub-modules. Regulated DC output feeds the SMC CJ1B4-10U4 PLC power supply module, which in turn distributes logic-level power across the CJ-series backplane I/O slots. This architecture ensures clean, isolated power rails for both the LEICA measurement controller and the OMRON PLC CPU/I/O subsystems, minimizing ground loop interference in high-precision measurement environments.

Technical FAQ
Q: Is the SMC CJ1B4-10U4 included with the 301-360.021 assembly?
A: Yes. This listing covers the complete assembly as described: the 301-360.021 CH-A chassis with 3× 944AOPLPNCSTS sub-modules and the SMC CJ1B4-10U4 PLC power module.
Q: What OMRON CJ-series CPUs is the CJ1B4-10U4 compatible with?
A: The CJ1B4-10U4 is compatible with OMRON CJ1 and CJ2 series CPUs and backplane configurations. Confirm your backplane slot count and power budget before ordering.
Q: Can this unit be used as a standalone power supply without the LEICA CMM?
A: The 301-360.021 CH-A is designed as an integrated assembly. The SMC CJ1B4-10U4 module can be separated for standalone CJ-series PLC use; consult our technical team for configuration guidance.
Q: What is the warranty on surplus units?
A: Konmask.com provides a 90-day DOA (Dead on Arrival) warranty. Extended warranty options available upon request.
Q: Do you provide a certificate of conformance or test report?
A: Yes. A functional test report is available upon request at time of order.
