10-1-2. External signal output function
An ON signal is output when one or more units are in operation, and an Error signal is output when one or more
units are in error. (Operation status (On/Error) of the units that are connected to each EW-50 will be output.)

Note
● The relays, lamps, DC power supply, diodes, and extension cables are not supplied.
● The total length of the lead wire and extension cable should not exceed 10 m (32 ft). (Use an extension cable of 0.3 mm
thicker.)
● Each element will turn on during operation and when an error occurs.

*1 Select an external power supply suitable for the relays used. (12 or
24 VDC)
Connect the external power supply in the correct polarity to input
and output the signals.
Connect ① (shown in the figure at left) to the negative side.
*2 Use a diode at both ends of the relay coils.
Important
● Be sure to use an external power supply (12 or 24 VDC)
to avoid malfunctions.
● Connect the external power supply in the correct
polarity to avoid malfunctions.
● Do not connect the external power supply without
relays being connected to the controller (no load).
