	potentiometer
V1	0-10V Analog Voltage input	22 AWG, 0.3 mm2	0.4
I	0-20mA Analog Current input	22 AWG, 0.3 mm2	0.4
AM	Multi-function Analog output	22 AWG, 0.3 mm2	0.4
MO	Multi-function open collector	20 AWG, 0.5 mm2	0.4
	output T/M
EXTG	Ground T/M for MO	20 AWG, 0.5 mm2	0.4
P24	24V Power Supply for P1-P5	20 AWG, 0.5 mm2	0.4
30A	Multi-function relay A/B	20 AWG, 0.5 mm2	0.4
	contact output
30B		20 AWG, 0.5 mm2	0.4
30C	30A, B Common	20 AWG, 0.5 mm2	0.4

Note: Tie the control wires more than 15cm (6 in) away from the control terminals. Otherwise, it interferes with front cover reinstallation.

Note: When you use external power supply for multi-function input terminal (P1~P5), apply voltage more than 12V to activate.
