Zone 1 Remote I/O

BEX1 PROFINET

Remote IO 8AI-8AO-8DI-8DO

Worldwide first decentralised and compact Remote IO system with Profinet for the hazardous area Zone 1/21.
BEx1 includes busnode, isolation amplifier and 32 intrinsically safe IO channels with four different functions on smallest space.
The module can be installed in Zone 1/21 with a certified Ex e enclosure and connects sensors and actuators from Zone 0/20.
Feature
▪ Fully potted → extreme robust
▪ 32 channels for sensors and actuators
• 16 digital (8x Input and 8x Output)
• 16 analog (8x Input and 8x Output)
▪ None configuration on module required
▪ Separate power supply for sensor and actuator
▪ Comprehensive diagnostics for each channel
▪ Galvanic separation between channel and system
▪ Easy rail mounting or via mounting holes
▪ Made for Namur Sensors
