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. T
o 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.
