Junction module (JX/JM)

Features

The explosionproof junction module is suitable for use in corrosive process environments with hard conduit or flexible wiring systems. It features external drop switching capability with explosionproof ratings for use in hazardous zone 1/Div 1 areas. Components are preinstalled in the housing.

Select from:

Drop connectors
Switched drop connectors
I/O modules
Relay modules
Specialty applications

Wide variety of options to meet the needs of network applications in hazardous and general purpose locations

The JX includes a full array of drop connectors, I/O modules, and other network accessory items for most common industrial fieldbus networks. With cFMus Class I Div 1 and Class I Div 2 and ATEX/IECEX approvals, these rugged and corrosion resistant devices are an essential tool for building your network infrastructure.

New JX drop connectors feature raised module

The new JX drop connector modules are elevated from the base of the enclosure. This allows for easier wiring to the terminals and improves LED visibility.
The new JX has many improvements over the JM including non-contact disconnect switch, larger LEDs, and worldwide hazardous location approvals.
The JX has cFMus XP and NI approvals as well as ATEX / IEXEx Exd approvals.
