Contact Output Circuit
Five contact output circuits (4 welding power source specific outputs
(arc-ON, wire inching, wire retract inching, starting point detection
command (optional function)), and 1 universal output) are available
.

Insulation by photocoupler
Output current per point
0.5A (DC, AC, 250 V)
1)
1 This is a maximum value in the case of the resistive load. Maximum rate
differs depending on the type of the load (AC/DC, resistive/inductive/capacity
load). Relay contact sticking, and open-close life reduction may occur. When
connecting the inductive load, install elements such as flywheel diode on the
load side. In the case of using I/O current (+24 VU), maximum of approx.
500 mA can be taken out (fuses F1, F2 may blow out when the current
exceeds the above limit).
Number of commons
No common connection.
Independent for each output.
Active level
0 output = "Contact ON", 1 output = "Contact OFF"
Output protection type
JIS B3501, Output with no protection
