The ISE Series of Intrinsically Safe Barrier 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.
The compact 17.5mm wide enclosure can be both mounted on 35mm DIN rail or
panel-mounted with two screws. Terminals for the input devices from the Hazardous
area are on the bottom for easy access in the enclosure to incoming field wiring
from the hazardous area.
Operation
Each ISE Series relay consists of an intrinsically safe input, a corresponding
normally-open relay output, and a bi-color LED for status indication. With input
voltage applied, the LED will be ON (GREEN) to indicate power is applied. When
the output contact is closed, the LED is ON (ORANGE). The ISE series comes in
Standard and Inverted configurations.
Configurations
Standard Logic (ISEUR1):
When the input device is closed, the corresponding output contact is closed. When
the input device is open, the corresponding output contact is open.
Inverse Logic (ISEUR1V):
When the input device is open, the corresponding output contact is closed. When
the input device is closed, the corresponding output contact is open.
