Phoenix Contact 2967280

The Relay Module, designated as PLC-RSC-48DC/21-21AU, integrates a PLC-BSC.../21 basic terminal block equipped with a secure screw connection and a plug-in miniature relay. This module is specifically designed for DIN rail mounting on NS 35/7.5. It supports input voltages of 48 V DC, with a range of 40.3 V DC to 60 V DC at 20 °C.

Equipped with two changeover contacts, this module operates with a typical input current of 20 mA and features a monostable drive mechanism. The relay exhibits a response time of approximately 8 ms and a release time of around 10 ms. Its construction includes a contact material of AgNi, which is hard gold-plated, ensuring reliable performance with a minimum switching voltage of 5 V AC/DC and a maximum switching voltage of 250 V AC/DC.

With a mechanical service life rated at 3 x 10⁷ cycles and an operating factor of 100%, the module is designed for universal applications. It is protected against reverse polarity and features an operating voltage display via a yellow LED. Furthermore, the relay is compliant with relevant EMC and Low Voltage directives, assuring its suitability for various industrial environments.

In terms of physical specifications, the module measures 14 mm in width, 80 mm in height, and 94 mm in depth, and it is housed in a gray casing (RAL 7042) with a flammability rating of V0. It operates within an ambient temperature range of -40 °C to 60 °C, making it ideal for diverse operational conditions.
