## **1-CHANNEL INTRINSICALLY SAFE RELAYS ISE Series** 

The ISE Series of Intrinsically Safe Relays provide a safe and reliable method to control a single load (motor starters, relays, etc.) with a single input device (switches, sensors, etc.) located in a hazardous area. These products are approved for use in Class I Groups A, B, C, D, Class II Groups E, F, G, and Class III Hazardous Locations (Zones 0 & 1 in Canada). The ISE Series relay must be mounted in a safe area, following Macromatic Control Drawing Number ISD2A01, as shown in Instruction Sheet 901-0000-329. 

-  Approved for use in Class I, Class II, and Class III Hazardous Locations (Zones 0 & 1 in Canada) 

-  1-Channel 

-  5A relay output 

-  Universal input voltage of 102132V AC & 10-125V DC 

-  Compact 17.5mm wide enclosure for both DIN-rail or panel-mount 

-  LED status indicator 

(U)us **UL913 8th Edition** 

The ISE Series relays utilize a compact 17.5mm wide enclosure that can be both mounted on 35mm DIN rail or panel-mounted with two screws. Hazardous terminals are on the bottom of the unit for easy access in the enclosure to incoming wiring from the hazardous area and are clearly marked. 

## **Standard Operation** 

Each ISE Series relay consists of an intrinsically safe input and a corresponding electromechanical relay output.  There is one bi-color LED for status indication. With input voltage applied, the LED will be ON (Green) to indicate power is applied. 

When the input device from the hazardous area is _closed_ , the output relay is energized and the LED is ON (Orange). When the input device _opens_ , the output relay will de-energize and the LED will be ON (Green). 

## **Inverted Operation (V-suffix)** 

Each ISE Series relay consists of an intrinsically safe input and a corresponding electromechanical relay output. There is one bi-color LED for status indication. With input voltage applied, the LED will be ON (GREEN) to indicate power is applied. 

When the input device from the hazardous area is _open_ , the output relay is energized and the LED is ON (ORANGE). When the input device _closes_ , the output relay will be de-energized and the LED will be ON (GREEN).
