Figure 4.8 Terminal Numbers
•
Connector 1 provides four programmable digital
inputs terminals, two additional digital terminals
programmable as either input or output, a 24 V
DC terminal supply voltage, and a common for
optional customer supplied 24 V DC voltage
•
Connector 2 terminals (+)68 and (-)69 are for an
RS-485 serial communication connection
•
Connector 3 provides two analog inputs, one
analog output, 10 V DC supply voltage, and
commons for the inputs and output
•
Connector 4 is a USB port available for use with
the MCT 10 Set-up Software
