Specification & Description
The Phoenix Contact 2700356 is a high-performance coupling relay designed to facilitate the safe and reliable interfacing of digital output signals from fail-safe controllers to input/output devices such as valves and actuators. This component is particularly suitable for SIL 3 high and low-demand applications, ensuring compliance with stringent industry standards for functional safety.
Crafted with a compact form factor, the relay boasts a minimal housing width of just 6.8 mm, making it an ideal choice for space-constrained environments. The relay features one enabling current path, one confirmation current path, and one digital signal output, which are essential for the electrical isolation and power adaptation required in sophisticated control systems.
The relay's construction includes forcibly guided contacts in accordance with EN 50205, providing an additional layer of operational security. The integrated signal contact simplifies the proof test process as per IEC 61508, enhancing the ease of maintenance and testing.
With a focus on longevity, the Phoenix Contact 2700356 is engineered to withstand the rigours of industrial use. It includes a test pulse filter that extends the service life by mitigating the effects of controller test pulses. The relay operates within a wide ambient temperature range, ensuring reliability even in extreme conditions.
This coupling relay is a testament to Phoenix Contact's commitment to quality and innovation, offering a robust solution for those seeking to enhance the safety and efficiency of their automated systems.
