Phoenix Contact Safety Relay Modules & Sensors
Phoenix Contact Safety Relay Modules and Sensors are SIL-certified and allow for easy installation and configuration of the modules. By utilizing safety relay modules, safety functions can be reliably implemented in machines and systems. These products monitor signals from light grids, emergency stop buttons, and safety door switches, initiating a safe state when necessary. Phoenix Contact safety relay modules are TÜV-certified in accordance with EN ISO 13849 up to PLe or IEC 61508 up to SIL 3.
Safety Relay Modules
The safety relay modules are based on relay technology and feature force-guided contacts in accordance with EN 50205. They reliably monitor functions in machines and systems. Due to their redundant structures, these safety relays ensure a safe state and are ideal for machines and systems that require a few safety functions and logic operations to be implemented.
Safety Functions
• Emergency stop
• Monitoring of movable guards, such as safety doors
• Electrosensitive protective equipment
• Two-hand control devices up to type IIIC
• Zero-speed monitoring and seed monitoring
Force-Guided Contacts
A safety relay module with integrated monitoring uses a forced guided property for fault detection, reliably detecting serious faults and achieving a high safety level.
How Does This Work?
The N/O and N/C contacts of an elementary relay are connected to each other mechanically through forced guidance, preventing N/O and N/C contacts from closing at the same time. When combined with a suitable circuit, failure to open can be reliably detected, reliably ensuring maximum safety for both people and machinery.
