MI3 Multi-function Input 3
MI4 Multi-function Input 4
+24V DC Voltage Source
The common terminal is only used for a multi-function
input terminal.
Output voltage: 23–25V, load capacity: 20 mA
+24V terminal is only used for digital control signal
common when in the internal power supply PNP mode.
(Or used for digital control signal common when in the
external power supply NPN mode.)
For detailed wiring instructions, refer to NPN and PNP
mode description.
NOTE
Do not use the +24V terminal for other external power
loads to avoid damage to the hardware circuit.
DCM Digital Signal Common (Sink) Common for multi-function input terminals.
SG+
Modbus RS-485
Internally connected to RJ45 terminal PIN5 and PIN4,
providing flexible choice for users (only support one
of
them at one time).
