- For driving various loads using PLC output signals
- Redundant circuits and signal feedback for safety
- Available in 4-pole and 6-pole models
- Compact, space-saving size
- Available in screw type and screwless type models
- Operation indicator (green LED) for easy status monitoring
- DIN rail mount and screw mount installation (varies by models)

System Configuration:
Safety relay terminal blocks can be used to control various loads with input signals from safety light curtains and switches. It can also be used for feedback signals to offer safer control systems.
Force Guided Contacts and Feedback Signals:
SFT series utilize relays with force guided contacts to prevent contact welding, in accordance with IEC 61810-3. The status of output contacts can be sent with feedback signals to safety controllers or other devices, allowing safer operation of control systems.
Compact Size:
The compact size (22.5mm width and 48.8mm height) maximizes space efficiency. (4-pole model)
Operation Status Indicators:
Green LED indicators are available to check operation status
Screw Type, Screwless Type Models Available:
The SFT series is available in screw type and screwless type wiring models. The screwless push-in type connection provides easy wiring, reduced installation time, and even tightening.
Flexible Mounting Methods:
The SFT series supports both DIN rail mount and screw mount methods, for application in diverse environments.
※ Screwless type does not support screw mount method.
Applications:
Automobile Assembly Process: Safety relay terminal blocks are used during automobile assembly process to receive and deliver safety controller input signals which control actuator.
