The Macromatic ISDUR4 is a 4 channel intrinsically safe relay. This DIN-rail or panel mount relay has an input voltage of 102-132VAC / 10-125VDC. It helps to monitor up to four loads from a hazardous location and has an output of 5A SPST-NO. It can be used in Class I Div 1 Groups A, B, C, and D, Class II Div 1 Groups E, F, and G, and Class III Div 1. It has a 60mm wide housing. The inputs and isolated outputs each have 2 terminals. The LED shows the status of the relay. Easier wiring is provided by the pluggable terminal blocks. Please note that the relay itself needs to be installed in a safe area.

The V LED is green when the voltage is introduced. The input LED is green while the input device is closed. The output LED is orange when the relay is energized. This four channel relay has four modes of operation, including Standard Logic, Inverse Logic, No Time Delay, and Fixed 2 Second Delay (see Instructions tab). Two DIP switches on top allow the user to select between Standard or Inverse Logic and a 0 Second or 2 Second Time Delay. Can be installed on a 35mm DIN-Rail or on a panel with two #8 screws with the DIN-Rail clips extended.
