Remote Control Function - Omron S8VM Product Manual

Remote Control Function

This function turns outputs ON and OFF using an external signal
while input voltage is applied, using the +RC pin (pin 7 on CN) and
the -RC pin (pin 8 on CN). Connect a switch or transistor to the +RC
and -RC pins to use the remote control function. When not using this
function, the +RC and -RC pins are shorted by using the standard
supplied connector.

CN
RC Level for RC
Short or L (0 to 0.8 V) ON
Open or H (2.4 to 12 V) OFF
Maximum input voltage: 12 V max.
Maximum allowable reverse voltage: 1 V max.
Sink Current: 3.5 mA
Note: 1. Use 2-conductor shielded cable or twisted-pair cable as
connection wire.
2. The remote control circuit is isolated from the input and out-
put circuits of the power supply.
3. Remove the standard supplied connector and prepare a
connector separately.
Power Failure Alarm Function
The power failure alarm indicator will light red to indicate an output
voltage error if overload, overvoltage, or overheat protection is acti-
vated, if a drop in the input voltage causes the output voltage to drop,
if the built-in fan motor stops, and during remote control standby. The
alarm is also output externally by a transistor.
Transistor output: 30 VDC max., 50 mA max.
Residual voltage when ON: 2 V max.
Leakage current when OFF: 0.1 mA max.
Alarm detection voltage: Approx. 80% of output voltage setting
During detection, the transistor is OFF (with no continuity across pins
11 and 12 on CN), and the LED (red) lights.

Note: 1. This function monitors the voltage at the Power Supply out-
put terminals. To check actual voltage, measure the voltage
on the load side.
2. Outputs are forced OFF if the built-in fan motor stops
(S8VM-15224C only).
3. Remove the standard supplied connector and prepare a
connector separately.
