Signal description
R1A / R1B / R1C
R2A / R2C - R7A / R7C
Relay output
Programmable output, contact rating: 250VAC / 3A or 30VDC / 1A
•
RB, RC: normally closed; RA, RC: normally open
Note:
Limit the current within 3A if relay terminal is to connect to AC 220V voltage signal.

Control Terminal Wiring
To reduce the interference and attenuation of control signal, length of control cable should limit within
50m. There should be more than 0.3m between the control cable and the motor cable.
The control cable must be shielded cable. The analogue signal cable must be shielded twisted pair.
