JM Series Enclosure
Brand: Valmet
StoneL’s Junction Module (JM) enclosure is an environmentally hardened platform which is suitable for use in the most extreme corrosive and hazardous process environments.
The JM features a wide variety of bus networking capabilities for protocols used in the process industries. Because of its flexibility and functionality it has become an essential building block for bus network users in the processing industries.
Features- Keep bus energized during maintenance in Division 1 Areas FM approved factory-sealed leads are available for the drop leg of the switched drop connector. In Division 1 areas the conduit must not be opened to atmosphere when wires are energized. However, with factory-sealed leads no energized wires are exposed to the atmosphere when the drop leg is opened or removed for maintenance even though the bus trunk remains energized.
- Rugged enclosure This enclosure is constructed of durable, marine grade anodized aluminum with two coats of epoxy. Optional clear polycarbonate cover enables observation of circuit status without opening the enclosure.
- Vapor tight and submersible Rated for IP67 and NEMA 4, 4X and 6, the JM withstands rigorous washdowns and corrosive environments.
- Wide variety of functions Select from drop connectors, switched drop connectors, relay modules, I/O modules, power conditioners, and special module configurations.
