Operation can be checked easily because the ON/OFF status of all inputs and outputs can be seen at a glance. Moreover, the terminal block is clearly labeled for each function to prevent improper wiring.

Non-contact safety output

Non-contact safety output

Unlike conventional relay units that use mechanical contacts, the SC-S11 is free from failures caused by a fused contact. This ensures extreme durability, reducing maintenance and other costs.

Easily set with DIP switches

With conventional relay units, it was necessary to change most of the wiring of the device that was connected to the safety input depending on whether it was connected to a contact output (emergency stop switch) or a PNP output (e.g. Safety light curtain). Moreover, interlock and EDM functions had to be configured with wiring. The SC-S11 allows all of these settings to be activated easily with DIP switches, helping to prevent improper wiring or setting.

1: Contact output device connection (Initial setting)
2: PNP output device connection

Function setting switches (SW2)

Each setting is set with two switches.

Function setting switches (SW2)

Be sure to set both switches of each pair to the same position.
1. EDM is a function to detect the failure of an external device.

Automatic reset mode

If the safety input is on when the power is turned on, the safety output will automatically turn on. If the safety input is turned from off to on, the safety output will automatically turn on.

Manual reset mode

Even when the power is turned on or the safety input is turned from off to on, the safety output will remain off. A reset input is required to turn on the safety output.

Various I/O functions

Various I/O functions

Lockout output

Users are notified when lockout occurs due to the failure of an external device or other problems.

Auxiliary output

The ON/OFF status of the safety output is linked with the auxiliary output. This can be used to monitor the status of the SC-S11 with a general-purpose control PLC.
* These non-safety outputs support both PNP and NPN inputs.

External OFF input

This input is used to turn off the safety output with an external signal. This can be used to test whether the safety function works properly.

EDM input

This input is used to detect the failure (fused contact, etc.) of an external device. The normally closed contact of the external device is connected to this input.
