input circuit

1) Line Amplifier I/F
This is a good signal transmission method that is
less sensitive to noises. We recommend you to
use this to maintain the reliability of signals.
2) Open Collector I/F
This uses an external control power supply(VDC).
This requires a current-limiting resistor correspond-
ing to the capacity of the VDC value.

Connecting to

sequence input signals

Connect to a contact of switch and relay, or a tran-
sistor of an open collector output.
Use a switch or relay for micro current so that in-
sufficient contact can be avoided.
Can be used with COM- instead of COM+
