Phoenix Contact 2700466

The PSR-MC20-3NO-1DO-24DC-SC is a safety relay suitable for emergency stop and safety door functions, achieving up to SIL 1, Cat. 1, PL c, and potentially reaching SIL 3, Cat. 4, PL e depending on the specific application. This relay operates on a 24 V DC supply and features 1-channel functionality with options for both automatic and manual start.

Equipped with three enabling current paths, it utilizes an electromechanical relay with force-guided contacts in compliance with IEC/EN 61810-3. The typical response time is under 175 ms, and it ensures reliable operation with a maximum power dissipation of 4.8 W under nominal conditions. The relay's contact switching type supports a maximum switching capacity of 5 A (AC15) with a limiting continuous current of 6 A.

In terms of physical specifications, the relay dimensions are 12.5 mm in width, 112.2 mm in height, and 114.5 mm in depth, housed in a yellow PA enclosure. It supports screw terminal connections with a conductor cross-section ranging from 0.2 mm² to 2.5 mm². The device is designed for DIN rail mounting and can be installed in both vertical and horizontal positions.

Operating conditions are robust, with an ambient temperature range of -40 °C to 55 °C and a maximum altitude of 2000 m above sea level. It also complies with CE standards and is suitable for industrial use only.
