Product Overview

The Omron CS1W-CN713 is a 70 cm I/O connecting cable that links the CJ1W-IC101 (CPU rack I/O Control Unit) to the CJ1W-II101 (expansion rack I/O Interface Unit) in a CJ-series PLC expansion system. manufactured by Omron Corporation. Hengyixin Automation stocks this I/O expansion unit in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.

The '713' in the part number decodes as: leading '3' = CJ-platform compatible version (the older 'CN@@B' cables were for the CS1 platform and are physically compatible but the '3' suffix indicates the refreshed CJ1-compatible wiring), middle '7' = 7 × 100 mm = 0.7 m length. The cable terminates in high-density 40-pin connectors at both ends (IC101 on the CPU rack and II101 on the first expansion rack) and is rated for industrial environments with shielded jacket and strain relief boots.

Pick the CS1W-CN223 (2 m) for typical cabinet-to-cabinet installations where the racks are 1 to 2 m apart — gives some slack for service.

Key Features

  • Compatible with CJ1W-IC101 and CJ1W-II101
  • 40-pin ribbon-style construction terminated to round shielded cable
  • Compatible with CS1W-IC101 + CS1W-II101 for long-distance fibre-optic expansion
  • Double-ended high-density 40-pin connectors — keyed to prevent reverse installation
  • SKU: CS1W-CN713
  • Series: CS1W (CJ/CS I/O connecting cable family)

Best-Fit Applications

  • Adding a CJ1W-ID211 expansion unit on a small sub-panel beside the main control panel — the 0.7 m handles across-panel.
  • Standard CJ2M-CPU33 cabinet design with the expansion rack direct-mounted above the CPU in the same enclosure — keep cable runs.
  • NJ501-1400 panel with the CPU and first expansion rack within the same backplate — 0.7 m keeps the wiring tidy

Buying Checklist

  • Pick the CS1W-CN133 when the racks are geographically separated across a large machine
  • Pick the CS1W-CN223 when the racks are 1 to 2 m apart in adjacent cabinets
  • Pick the CS1W-CN713-CV when the cable runs next to VFD power lines and you need extra shielding

FAQ for CS1W-CN713

What is the length of the CS1W-CN713 cable exactly?
0.7 metres / 70 cm — the '7' in '713' is the length designator in decimetres (700 mm). This is one of the most common extension cable SKUs in the CJ/CS platform because it fits the standard in-cabinet layout of CPU rack directly above the first expansion rack. Note: the older CS1W-CN713-W and the CS1W-CN@@B variants are physically equivalent but lack the CJ1 platform version codes — pick the '3' ending (this SKU) for CJ1/CJ2 CPUs.
Is the CS1W-CN713 compatible with NJ-series controllers?
Yes — the NJ101, NJ301, and NJ501 Machine Controllers use the same CS1W-CN@@3 cable family for connection to CJ1W expansion racks. The NJ CPU communicates to expansion racks via the CJ1W-IC101 + CJ1W-II101 pair, which are then linked by CS1W-CN713 (this SKU) or another member of the CN family.
Can I daisy-chain two CS1W-CN713 cables for 1.4 m total length?
Yes, but with a caveat: each CS1W-CN713 connects a single CPU-IC101 or II101-II101 pair, so you can put a CS1W-CN713 between CPU and rack 1, and another between rack 1 and rack 2, etc. The combined length of all CS1W-CN@@3 cables in your system must not exceed 12 m. Two CS1W-CN713 cables totalling 1.4 m is well within limit. If you need 0.7 m, 1.4 m, or 2.1 m, you would need a CS1W-CN713 + CS1W-CN713 or CS1W-CN223.
Can I use a CS1W-CN713 with a CS1-series CPU?
Yes — the CS1W-CN@@3 cables are also compatible with CS1-series CPUs (CS1G, CS1H, CS1D). However, the CS1-series uses a different I/O Control Unit (CS1W-IC101) than the CJ-series (CJ1W-IC101), and the CS1W-IC101 + CJ1W-IC101 are NOT interchangeable. Always verify that the IC101 model matches the CPU family before plugging in the CS1W-CN713 cable. The cable itself is model-independent between CS1 and CJ.
