It transmits 16 points of I/O signals per word with a pair of cables. Easy and minimized wiring effort. This unit is available for CJ/NJ controller.
A CJ1W-B7A unit can transmit 64 points of I/O signals.
The slim body can downsize machines to which CJ1W-B7A is connected.
It is a basic I/O unit. No complicated setting and programs are required.

Note: 1. When separate power supplies are used, the B7A Interface Unit and B7A Link Terminal are supplied by separate
external power supplies.
2. When a common power supply is used, the B7A Interface Unit and B7A Link Terminal are supplied by the same
external power supply.
*1. We recommend OMRON S8[][]-series Power Supply Units for the external power supplies.
*2. The capacity of the external supply current does not include the capacity required by the B7A Link Terminal.
*3. The minimum input time is the minimum time required by the B7A Interface Unit to read the input signals from the
CPU Unit.
