Basic Information

Less setup time for safety circuits

UL/C-UL , CE , TUV , Korean S Mark Approved
UL : Approved Listing
Korea's S-mark certification : SF-C11/C13 only

Features

Quick-connection [SF-C11/SF-C14EX]

Connecting to the safety light curtain is done using plug-in connections, which shorten setup and replacement time.

Easy setup requiring no torque control [SF-C11/SF-C14EX]

A spring method is used for the terminal blocks for connections other than to the safety light curtain. There is no need to control tightening torques for these terminal blocks.

Removable terminal blocks reduce maintenance time [SF-C11/SF-C14EX]

Removable terminal blocks reduce the work required for reconnecting wiring during maintenance.

Metal enclosure with a IP65 protective structure [SF-C12]

The strong metal enclosure has a built-in safety relay. It has an IP65 protective structure, so that it can be set up individually without the need to be inserted into a control panel.

Slim design [SF-C13]

22.5 mm 0.886 in thickness, so it can even be inserted into narrow spaces inside panels.

The method used to build the safety circuit is selectable

It is possible to build muting control circuits using a stand-alone safety light curtain from the SF4B / SF4B-G series.
The SF-C14EX(-01) application expansion unit allows the safety light curtain, muting sensors and muting lamps to be connected together directly, so that muting control circuits can be built very easily.

Using the SF-C14EX(-01) internal circuits

Both safety and productivity can be obtained by stopping only one part of the device [SF-C14EX]

Three safety circuit systems packaged into a single unit!
Three safety circuit systems: ①Safety light curtain output circuit, ②Muting control circuit, and ③Emergency stop circuit are packaged into a single unit.
Functions that require multiple safety relay units and muting control units can be concentrated into a single unit, which results in large space savings, less wiring, and less installation work.

High-speed response 14 ms (Including safety light curtain)
High-speed response has been achieved due to the adoption of the semiconductor output. This avoids the response delays that occur when using more than one safety relay unit, greatly reduces the safety light curtain safety distance, and improves ease of working.
Of course, it is not necessary to exchange the safety relays within the unit anymore, which contributes to the reduction of running cost.

Motors that use muting control and those that do not use can be controlled independently! [SF-C14EX]

Controls the motors that use muting control (robots) and the motors that do not use muting control (turntables) with a single unit.
When the workpiece comes in, the turntable can be stopped and the robot can keep operating condition, to protect the safety of the operator and to maintain productivity.

Safety circuit ①: Linked to safety light curtain beam received / interrupted status (partial stop)
When the safety light curtain is interrupted (when an object enters or a person intrudes), this circuit switches off (open) the safety output and stops the turntable.

Safety circuit ②: Linked to muting control (partial stop)
If an object enters when the turntable has stopped normally, (muting condition is achieved), this circuit allows the robot to operate. If an object enters while the turntable is turning (muting condition is not achieved), this circuit switches off (open) the safety output and stops the robot.

Safety circuit ③: Linked to emergency stop input (all stop)
When the emergency stop button is pressed, this circuit switches off (open) the safety output and stops all equipment (turntable and robot).

Equipped with blown lamp output for muting lamp

If a lamp in one of the two muting lamps that are connected to the unit blows, a warning is output. It is possible to replace the lamp before both lamps blow and the equipment stops.
In addition, auxiliary output that is linked to the muting function, override function and safety light curtain control output is also available.

	Function	Operation
Auxiliary output 1	Muting output	ON when the muting function is invalid
Auxiliary output 2	Override output	ON when the override function is invalid
Auxiliary output 3	Blown lamp output	ON when the muting lamp is normal
Auxiliary output 4	Safety light curtain auxiliary output	ON when the safety light curtain is in light interrupted condition

Equipped with a digital indicator so that error details can be understood at a glance!

If a problem should occur, the same output (OFF signal) as if an object has been detected will be maintained in order to ensure safety, and the details of the error will appear on the digital display.
