Intrinsically Safe Barrier Relays Protect hazardous location circuits and control loads without additional relays or contactors. CIRCUIT PROTECTION AND CONTROL IN ONE COMPACT DEVICE Intrinsically Safe Barrier Relays provide low-cost protection when controlling loads with input devices located in hazardous areas. IS circuits operate at low-energy levels that cannot ignite potentially explosive atmospheres. In the event of a fault condition, the IS barrier prevents excess voltage and current from reaching the hazardous area. ISD SERIES: FOUR CHANNEL DIN-RAIL MOUNTED BARRIER RELAYS ISD Series barrier relays, with a 60 mm wide enclosure, mount on 35mm DIN-rail or can be panel-mounted with screws. These barrier relays provide a safe and reliable method to control up to four loads (motor starters, relays, etc.) with up to four input devices (switches, sensors, etc.) located in a hazardous area. Models are available for time delay or logic selection to be independently applied to each channel. Terminals are removable for easy connection. ISE SERIES: ONE-CHANNEL DIN-RAIL MOUNTED BARRIER RELAYS ISE Series barrier relays, with 17.5 mm wide enclosure, mount on 35mm DIN-rail or can be panel-mounted with screws. These barrier relays provide a safe method to control a single load with a single input device located in a hazardous area. ISP SERIES: ONE-CHANNEL PLUG-IN BARRIER RELAYS ISP Series barrier relays, with an 8-pin plug-in design with socket, can be mounted on 35mm DIN-rail or panel-mounted with two screws. These barrier relays provide a safe method to control a single load with a single input device located in a hazardous area.
