Phoenix Contact releases PLC relays that are dual-rated for ATEX and Class I, Division 2 hazardous locations.
The single-pole, double-throw relays measure 6.2-mm wide, while the double-pole, double-throw relays are 14-mm wide. The replacement relays are hot-swappable for easy maintenance.
The relay modules feature RTIII-sealed relays and safe isolation of coils and contacts according to DIN EN 50178. They are available with screw or spring-cage terminations for easy installation in crowded switching cabinets.
Hazardous gas and vapor are common in many industries, such as oil and gas equipment, refineries, process, painting and mixing chambers, mining, wastewater treatment, and other locations. These industrial environments are subject to explosive atmosphere, so the switching components require very high levels of reliability and safety.
