The PSR-SCP- 24DC/MXF1/4X1/2X2/B is a multifunctional safety relay suitable for emergency stop and safety door applications. It meets the requirements for Safety Integrity Level (SIL) 3, Category 4, and Performance Level (PL) e, ensuring high safety standards.

This device is equipped with four normally open (N/O) contacts, supports three safety functions, and features two shutdown levels. Its activation can be monitored automatically or manually, providing flexibility in various operational settings.

With a nominal input voltage of 24 V DC and a wide input voltage range of 0.85 to 1.1 UN, the relay draws a typical input current of 125 mA when relays are actuated. For non-actuated relays, the current is typically 55 mA. The relay's typical response time is 175 ms for monitored/manual starts and 250 ms for automatic starts, ensuring quick activation in critical scenarios.

Dimensionally, the relay measures 22.5 mm in width, 112.2 mm in height, and 114.5 mm in depth, allowing for easy integration into existing systems. It is designed for a maximum switching frequency of 0.5 Hz, with a mechanical service life rated at 10 million cycles, underscoring its reliability in continuous operation.

Connection is facilitated through a screw terminal block, accommodating solid or flexible conductors ranging from 0.2 mm² to 2.5 mm². The device is also equipped with a surge protection suppressor diode, enhancing its durability against electrical tran... [Mehr lesen]
