SC-2 is an open circuit detector can be used as safety support devices for high-risk automation and machine control applications.

•   Suitable for high-risk automation and machine control
•   Automatic or manual reset capability
•   DIN rail mounting

The circuit is used in combination with a 4-wire type mat switch, or edge/tape switch to detect line-disconnections.
Connect the 4-wire mat switch for example; then, connect a 100/200 V power supply.
Keep a low-level current flowing at all times, thereby keeping the relay contact built in the SC-2 ON (Between Output terminal⑥COM and ⑤) → (The light-emitting diode glows green.)
Under the weight of an individual, the voltage drops so that the relay contact goes OFF. (The light-emitting diode glows red instead of green.)
In the event of an open circuit or short circuit, the absence of voltage causes the relay contact to go OFF. (The light-emitting diode glows red instead of green.)
In the event of a power outage or blowout of a fuse, the relay contact goes OFF. (The light-emitting diode goes OFF.)
Either Self-maintaining circuitry or Direct-circuitry can be chosen on SC-2 circuit.
If a direct circuit configuration (without the need for resetting) is used, requires short-circuit of reset terminals 11 and 12 by lead wire.
