Compact, Ultra-Rugged Remote IO modules for Ex Zone 1/21 with Profinet or Modbus TCP/IP communications. The modules include an ethernet based bus node with up to 32 IO channels on the intrinsically safe version and up to 24 on the increased safety version. With a wide range of IO types available and an ultra-rugged housing, the Bex1 IP67 remote IO modules offer a unique, compact solution for interfacing to hazardous area instrumentation.

BEx1 IP67 modules can be installed directly in Zone 1/21 hazardous areas and connect to instrumentation from Zone 0/20 (Ex i version). With no additional enclosure required, the modules lend themselves ideally to mounting on even the most compact hazardous area rated machines and skids, cutting wiring down to a minimum. With the flexibility of daisy chaining multiple modules together, the system can be scaled up easily as IO quantities increase.

The modules have been designed to be used in harsh environments, including off-shore Oil and Gas rigs, chemical manufacturing facilities and paints and coatings factories.

We are an authorized ExRUGGED distributor shipping to locations in North America.
