Link Terminals with 10 I/O Points
B7A
Transmit Signals while Saving Space
and Wiring Effort
More economical than previous multipoint trans-
mission terminals.
Transmit 10 input signals over just 2 wires (or over
3 wires if only one terminal has power supply).
Models available with either screw terminals or
modular terminals.
Indicators provided on models with screw terminals
for easy visual confirmation of I/O signal status.
Three-wire NPN output sensor can be connected to
the B7A with screw terminals (two-wire proximity
sensors cannot be connected).
