This nest storing type relay output card insulates DCS status output card and motor driving circuit and connects them through the relay.
This card receives contact signal from DCS and at switching time when OFF-ON of contact signal, motor start relay contact (output-1) should be set at ON for certain period of time.
And at switching time when ON-OFF of contact signal, motor stop relay contact (output-2) should be set at ON for certain period of time.
Since one card stores 2 channels, start-stop of 2 motors can be done by one card.
Features
Output contact points consist of 2 contacts: 1 for motor start and the other for motor stop
Output-1: Dry voltage contact point output for motor start (A contact and B contact points change-over through jumper)
Output-2: Dry voltage contact point output for motor start (transfer contact point)
Furnished with test switch convenient for debugging of DCS or operation checking and LED for status display
Provided with jumper to connect internally both commons of motor start-stop relay contacts to simplify wiring. When common use is not needed, commons can easily be separated through internal jumper pin
