Force Guided Relays

Force guided relays, also known as safety relays, are essential components in safety-critical industrial control systems. These relays are designed with mechanically linked contacts that ensure normally open (NO) and normally closed (NC) contacts cannot be closed at the same time. This forced guidance principle is critical for maintaining safety integrity in applications such as emergency stop circuits, safety gates, light curtains, and interlock systems.
Because the contacts are mechanically linked, a failure such as a welded contact prevents the relay from changing to an unsafe state. This design enables reliable fault detection and high diagnostic coverage, allowing safety systems to monitor contact status and identify failures before unsafe conditions occur. As a result, force guided relays are widely used in machinery control systems where dependable monitoring of safety functions is required. Force guided relays are commonly integrated into safety relay modules and safety controllers that comply with applicable machinery safety standards. They are engineered for long service life and consistent performance under demanding industrial conditions, using durable contact materials and robust housings. Available mounting options include PCB-mounted designs as well as plug-in terminal configurations, providing flexibility for control panel and system integration.
FAQs
Q: What is a force guided relay?
A force guided relay is a safety relay with mechanically linked contacts that prevent normally open and normally closed contacts from being closed simultaneously, enabling reliable fault detection in safety circuits.
Q: Where are force guided relays commonly used?
They are commonly used in emergency stop systems, safety gates, light curtains, interlock switches, and machinery safety control circuits.
Q: Can force guided contacts be added to a standard relay?
No, force guided contacts cannot be added to a standard relay. Force guided relays require a specific mechanical design and are purpose-built for safety-critical applications.
Q: What configurations are available for force guided relays?
Force guided relays are available in multiple configurations, including single-pole, double-pole, and four-pole designs, with PCB-mounted and plug-in terminal options to suit different control system requirements.
Q: Which manufacturers offer force guided relays?
Common manufacturers of force guided relays include IDEC, specializing in industrial safety components.
