The Relay Module PLC-RSC-120UC/21AU is part of the PLC-INTERFACE product family, specifically designed for universal applications. It consists of a basic terminal block with a screw connection and a plug-in miniature relay equipped with multi-layer gold contacts. This module is intended for mounting on a DIN rail with a standard width of 35 mm and has one changeover contact.

Operating with an input voltage of 120 V AC, the input range extends from 93.6 V AC to 168 V AC at 20 °C. The relay exhibits a typical input current of 3.5 mA under nominal conditions and features a monostable drive with polarized polarity. With a mechanical service life rated at 20 million cycles, this module ensures durability and reliability in demanding environments.

Key specifications include a maximum switching voltage of 250 V AC/DC, a limiting continuous current of 6 A, and a short-circuit current rating of 200 A. The relay also incorporates a protective circuit with a bridge rectifier and is equipped with an operating voltage display indicated by a yellow LED. The construction allows for screw connections with a stripping length of 8 mm and accommodates conductor cross-sections from 0.14 mm² to 2.5 mm². The module is constructed from materials that comply with the flammability rating of V0 according to UL 94.

With an ambient temperature range for operation from -40 °C to 55 °C and storage conditions from -40 °C to 85 °C, the relay is suitable for a variety of environments. The module also meets...
