2981428 Product Description

The Phoenix Contact 2981428 is a versatile and reliable safety relay designed for monitoring emergency stop and safety door applications. Engineered to meet the stringent requirements of SIL 3 or Cat. 4, PL e according to EN ISO 13849, this safety relay ensures the highest level of operational safety for industrial environments.

Featuring both one- and two-channel operation, the 2981428 allows for flexibility in application, with the option for automatic or manual activation. It is equipped with three normally open (N/O) contacts and one normally closed (N/C) contact, alongside two N/O contacts with a dropout delay adjustable from 0.2 seconds to 300 seconds, catering to a wide range of safety scenarios.

The relay's plug-in screw terminal block ensures a secure and durable connection, while its compact dimensions (45 x 99 x 114.5 mm for the screw connection version) make it suitable for installation in space-constrained areas. The device operates within an ambient temperature range of -20 °C to 55 °C, with derating, and can be used in locations up to 2000 metres above sea level.

With a nominal input voltage of 24 V DC and a typical input current of 155 mA DC, the 2981428 is designed for energy efficiency. The relay also features LED status indicators for clear and immediate feedback on operational status.

This safety relay is an essential component for any industrial safety system, providing reliable performance and peace of mind in safeguarding personnel and equipment.
