(SS1) to "VOLT".
(Factory set: "VOLT")
For input in "VOLT"
mode:
Connect the control input on
the common side.
(No polarities) Use 12 to 24 VDC for the external power supply.
An approx. 10-mA input current is required by a
single contact.
Pay attention to the capacity of the power supply.
Use micro-current contacts. (Use contacts
of minimum applicable load of 12 VDC and
1mA or less.)
Set the INPUT selector
switch (SS1) to "NONE
VOLT".
For input in "NONE
VOLT" input
Use micro-current contacts. (Use
contacts of minimum applicable load
of 12 VDC and 1mA or less.)
