The PLC-RPT-12DC/21HC/EX is a relay module that incorporates a DIN-rail-mountable basic terminal block measuring 14 mm. It utilizes a Push-in connection system and includes a plug-in relay, which supports a power contact rated for 10 A, along with a single changeover contact. This module operates at an input voltage of 12 V DC, with an input voltage range spanning from 10.3 V DC to 16.8 V DC at 20 °C.

With a mechanical service life of up to 30 million cycles, this product is suited for applications involving high continuous currents. It features safe isolation and reinforced insulation, classified under overvoltage category III and pollution degree 3. The relay is designed with protective circuits including reverse polarity protection and a polarity protection diode.

Typical operational specifications include a response time of 8 ms and a release time of 10 ms, with a maximum switching voltage of 250 V AC/DC. The relay supports various conductor cross-sections, from 0.14 mm² to 2.5 mm², and is compatible with rigid and flexible conductors, accommodating AWG sizes from 26 to 14. The relay module is compliant with ATEX/IECEx standards for use in Zone 2 and Ex Zone Class I, Div. 2 environments.
