Omron B7A - B7 A;B7 As; Link Terminals with 16 I;O Points

16
Link Terminals with 16 I/O Points (Screw Terminal
and Modular Models)
B7A/B7AS
Transmit Signals while Saving Space
and Wiring Effort
More economical than previous multipoint trans-
mission terminals.
Transmit 16 input signals over just 2 wires (or 3
wires if only one Terminal has power supply.)
Models available with normal I/O delay time
(19.2 ms typical) or short I/O delay time (3 ms
typical).
Models available with the HOLD function or LOAD
OFF function for processing transmission errors.
A series of B7AS models as compact as 10-point
screw terminal models are available.
