Product Overview

The Omron CJ1W-ID261 is a 64-point DC24V digital input unit for the CJ-series PLC rack, used with CJ1M, CJ1, and CJ2 CPU units. It is manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports. Specifications on this page were checked against Omron's CJ-series I/O Unit listings.

FAQ for CJ1W-ID261

What is the difference between CJ1W-ID261 and CJ1W-ID262?
Both are 64-point DC input units on the same Fujitsu connector pattern. The CJ1W-ID261 is the static-input model with 8 ms default response. The CJ1W-ID262 adds dynamic-input capability and a faster response, which is useful on high-speed counting or indexing lines. Pick ID261 for standard machine I/O; pick ID262 when the application needs the dynamic input feature.
Which connector fits the CJ1W-ID261?
The CJ1W-ID261 uses a Fujitsu-compatible 40-pin connector (one per 32 points). The matching Omron option is the XW2Z series cable, and the field side is normally a Fujitsu FCN-360 or FCN-365 compatible plug. Two connectors are needed for the full 64 inputs. Pre-wired terminal blocks are also available through Omron's XW2B / XW2D lines.
Can the CJ1W-ID261 be used with a CJ2 CPU?
Yes. The CJ1W I/O family is supported on CJ1, CJ1M, and CJ2 CPU racks. Up to three CJ1W expansion racks can be added to a CJ2 system, and the I/O tables in CX-Programmer / Sysmac Studio register CJ1W-ID261 modules automatically. The unit draws 90 mA max. at 5 VDC from the rack.
