X1 terminal interface type
The followings introduce the X1 various interface circuits and the wiring ways with the
host-controller.
1.
Digital input interfaces (C1)
For carrying on a control, the digital input interface circuit can be constructed by switch,
relay, open-collector triode, and photo-coupler and so on. To avoid contacting problem the
relay must be chosen with low current operation. External voltage is in the range of
DC12V~24V.
