Intrinsically Safe Barrier Relays

Macromatic's Intrinsically Safe Barrier Relays provide a safe and reliable method to control loads (motor starters, relays, etc.) with input devices (switches, sensors, etc.) located in a hazardous area. These products are approved for use in these Hazardous Locations:

Class I, Div 1 (Zones 0 and 1 Canada), Groups A, B, C, D
Class II, Div 1 (Zones 20 and 21 Canada), Group E, F, G
Class III, Div 1

Intrinsic safety is based on the principle of preventing low-voltage circuits in hazardous areas from releasing enough energy to ignite potentially explosive atmospheres.  In normal operation and in the event of a fault, the Intrinsically Safe Barrier protects the field circuit by preventing excess voltage and current from reaching the hazardous area.

4-CHANNEL | 60MM ISD Series: Controls up to four loads with up to four inputs from the hazardous area.  For both DIN-Rail or Panel-Mounting.
1-CHANNEL | 17.5MM ISE Series: Controls a single load with a single input from the hazardous area.  For both DIN-Rail or Panel-Mounting.
1-CHANNEL | PLUG-IN ISP Series: Controls a single load with a single input from the hazardous area.  Uses an 8-pin plug-in enclosure that can be both DIN-Rail or Panel-Mounted.
