•
Connector 1 provides 4 programmable digital
inputs terminals, 2 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. FC
302 and FC 301 (optional in A1 enclosure) also
provide a digital input for STO function.
•
Connector 2 terminals (+)68 and (-)69 for RS485
serial communication connection.
•
Connector 3 provides 2 analog inputs, 1 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.
