7 Contact I/O Circuit
7.1 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
.
Number of outputs and
application
5 outputs ARCON
WIRINCH

OUT
Stick start command
(Refer to the note 1)
Wire inching command
Wire retract command
Starting point detection
General output
Output method Relay contact output
Insulation method 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
