Terminal Block Unit
3. When using multi-conductor cables, separate the input- and output cables.
Besides direct connection as described above, it is also possible to make all the
connections for the external signals to screw-terminals. This is easier and less
time-consuming than soldering the wires to the external connector. For this pur-
pose you should use a Terminal Block Unit. The following Terminal Block Units are
recommended for using together with the CJ1W-CT021 High-speed Counter Unit:
• XW2B-40G4, which has 40 screw -terminals (M2.4) available
• XW2B-40G5, which has 40 screw -terminals (M3.5) available
These Terminal Block Units can be mounted to a DIN-rail or can be mounted using
screws. The connector on front of the Unit should be connected to a Terminal
Block Unit through a standard (40 wire) cable. For this purpose you can use the
standard available cables with product-number XW2Z-xxxB. The length of the
cable is indicated by 'xxx' in centimetres. The following cables are available:
• XW2Z-050B (0.5 m)
• XW2Z-100B (1 m)
• XW2Z-150B (1.5 m)
• XW2Z-200B (2 m)
• XW2Z-300B (3 m)
• XW2Z-500B (5 m)
The next figure shows how to use the Terminal Block Unit in a typical configuration
together with the CJ1W-CT021 High-speed Counter:
