17 /19 EX_24V External power input (24V) -
18 /20 EX_GND External power input (GND) -
1 Wiring of general output interface
The wiring of general output is as follows:
"YJTDPOUSPMNPEVMF
&YUFSOBM7%$
&9 @7
&9 0
-PBE
&YUFSOBM7
&9 @7
◆
To ensure normal operation of the output interface, use external
power supply for EX_O, and connect EX_24V to 24 VDC power and
EX_0V to 0 V.
◆
When external power supply is used, the maximum continuous
output current of a single I/O circuit is 0.35 A.
1 ) When driving relay load (be sure to connect a ywheel diode to prevent damage)
