Terminal Description
PWR 100 to 240 V AC or 24 V AC/DC
For a 24 V AC/DC power source, do not confuse polarity when using
direct current (DC).
24 V AC/DC: Only for the KT4R model
EV1 Event output EV1
EV2 Event output EV2
O1 Control output OUT1
RTD RTD input
TC Thermocouple input
DC Direct current, DC voltage inputs
For DC voltage input, (+) side input terminal number of 0 to 5 V DC, 1 to
5 V DC, 0 to 10 V DC differs from that of 0 to 1 V DC.
