Control Logic Signal Specifications
The control logic connectors are located just behind the front housing cover. The relay
contacts are just to the left of the logic connectors. Connector labeling is shown below.
Terminal Name
Description
Ratings
P24
+24V for logic inputs
24VDC, 100mA. (do not short to terminal L)
PLC
Intelligent input common
To change to sink type, remove the jumper
wire between [PLC] and [L], and connect it
between [P24] and [PLC]. In this case,
connecting [L] to [1]~[7] makes each input
ON. Please remove the jumper wire when
using external power supply.
