The Macromatic ISDUM4 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. It has isolated outputs, and the input & output terminals support 2 wires. 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 suitable enclosure.

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 output relay is closed. This four channel relay has four modes of operation, including Standard Logic, Inverse Logic, No Time Delay, and Fixed 2 Second Delay (see Instruction manual). Eight DIP switches on top allow the user to select between Standard or Inverse Logic and a 0 Second or 2 Second Time Delay separately for each channel. Can be installed on a 35mm DIN-Rail or on a panel with two #8 screws with the DIN-Rail clips extended.
