Interface Circuit (Input Circuit)

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+
