PLUG-IN INTRINSICALLY SAFE BARRIER RELAYS

ISP Series

The ISP 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.

 Approved for use in these

Hazardous Locations:

Class III, Div 1

 1-Channel

 Terminals support 2-wire inputs

 Input voltage of 120V AC

 Isolated 10A relay output

 Plug-in design for easy

installation and replacement

LED status indicator



The ISP Series relay must be installed following Macromatic Control Drawing
Number ISR2A01D as shown in Instruction Sheet 901-0000-260.

The ISP Series relays utilize an 8 pin plug-in design with socket (included) that
can be both mounted on 35mm DIN rail or panel-mounted with two screws.

Operation

Each ISP Series relay consists of an intrinsically safe input and a corresponding
normally-open relay output. There is one LED for status indication. With input
voltage applied, the LED will be OFF. When the input device is closed, the output
contact is closed and the LED is ON (Green). When the input device is open, the
output contact is open and the LED will be OFF.
