Operation
Note: The undermentioned is common for all B7A-series Link Terminals.
Connection of B7A and Programmable Controller
Each terminal of the B7A should be used for only single signal transmission without a transmission host. Therefore the B7A cannot be con-
nected to OMRON’s SYSMAC BUS Remote I/O System. To transmit signals from the B7A to a PLC, connect the B7A’s terminals to an I/O Unit
mounted on the PLC.
Refer to
B7A-series Models with PLC Connectors and Connecting PLCs on page 39 for details.

Note:
1. An independent power supply for the PLC is required due to the difference in operating voltage between the PLC and B7A.
2. An external interface unit is required.
