The PLC-RSC- 48DC/21-21 is a relay module designed for universal applications, incorporating a basic terminal block (PLC-BSC.../21) with a screw connection. It includes a plug-in miniature relay equipped with power contacts, suitable for installation on a DIN rail (NS 35/7.5). This module features two changeover contacts and operates with a nominal input voltage of 48 V DC, with an input voltage range of 40.3 V DC to 60 V DC at 20 °C.

Notable for its robust mechanical service life of 3x10⁷ cycles, the relay module demonstrates a maximum power dissipation of 0.96 W under nominal conditions. It is built to withstand a test voltage of 4 kV AC for one minute between winding and contact, and 2.5 kV AC for the same duration between changeover contacts. The relay's rated surge voltage stands at 6 kV.

Additional features include a typical response time of 8 ms and a release time of 10 ms, with protective circuits against reverse polarity and a polarity protection diode. The relay supports an interrupting rating of 140 W at 24 V DC and a switching capacity of 2 A, making it suitable for versatile control tasks. The module is compliant with various standards including IEC 60947-5-1 and is designed for mounting in any position on a DIN rail.
