Notes on Wiring
5.1
Wiring for Differential Communication
a.
Wire length should be minimized (Max: 500m shielded, 300m unshielded).
b.
Please use twisted pair cables conform to the impedance matching.
c.
If wiring is to be exposed to lightning or surges, use appropriate surge
suppression devices.
d.
Keep AC wiring separated from signal wires.
e.
Keep high energy and rapidly switching DC power wiring separated from
signal wires.
Wiring for Digital Output
Digital output voltage range: 24VDC (-15%/+20%)
The maximum output voltage per point is 50mA, please take this into consideration
when wiring.
Wiring for Digital Input
Digital input voltage range: 15~28VDC (ON), 5V (OFF)
Input impedance: 3 KΩ
Please take this into consideration when wiring.
