The I/O interface makes it possible to connect additional sensors and actuators.
They are connected by means of an included plug.
•
8 analogue inputs (0 to 10 V) (AIN0 to AIN7)
•
8 digital inputs (DI0 to DI7)
•
8 digital outputs (DO0 to DO7)
•
2 relays for additional actuators (REL0 and REL1). The relays can be connected to
the common contact (CO) as Normally Closed (NC) or normally open (NO) to the
contacts.
