Brand: Ronan Engineering

Product Inquiry


Intrinsic Safety Barriers are devices which limit the power (energy) that can be delivered from a safe area into a hazardous area. Explosions are therefore prevented, not just contained, in explosion-proof conduit and heavy cast housings. Electrical energy (voltage and current) and total energy are held within safe limits, eliminating the possibility of an explosion due to excessive heat.

The Ronan Intrinsic Safety Barriers Series X57 are plug-in modules containing one to four channels. Up to 20 barrier modules can be installed on a surface mount chassis.  Can be installed in Surface and/or DIN Rail Mount Chassis.
