X57 Intrinsically Safe Barriers
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 Systems Intrinsically Safe Barriers Series X57 are plug-in modules shunt zener diode type containing one to four channels. Up to 20 barrier modules can be installed on a surface mount chassis with optional ground bus or back plane with cable connectors.
