KEYENCE GC-S1R Safety relay output unit

Core Features

•  
• ✓  Direct-drive main contactor: Directly controls the coil of the motor's main circuit contactor (eliminating the need for intermediate relays), simplifying wiring.
• ✓  High-reliability disconnection: Mechanical contacts are more reliable than semiconductor switches in applications requiring extremely high electrical isolation and surge protection.
• ✓  Multi-channel independent control: Utilizes three sets of independent contacts to control different safety circuits (e.g., one circuit cuts off the motor power, another cuts off the hydraulic valve, and yet another sends a stop signal to the PLC).
• ✓  Advanced equipment retrofit: Replaces existing traditional safety relays while retaining the relay output wiring conventions, achieving a higher safety level (PLe).

Q: What are the main functions of the GC-S1R?

A: It provides an additional safety relay output (3A contact) to the main controller for directly driving high-power loads (such as contactors and motor starters) or as a highly reliable cut-off signal.

Q: What is the installation method for GC-S1R?

A: It is installed directly in the right expansion slot of the GC-1000/GC-1000R main unit.

Q: In which fields is GC-S1R suitable for application?

A: Its core value lies in providing three independent sets of high-current (6A/250V) safety relay contacts. This makes it particularly suitable for industrial scenarios that require direct disconnection of high-power loads, electrical isolation, or multiple independent safety signals.
