| Manufacturer Product Number | ISDUR4 |
| Description | Intrinsically Safe Relay; Class I/II/III Div 1; 4-Ch; Logic all Ch. |
| Datasheet | Download Datasheet |
The Macromatic ISDUR4 is a 60 mm intrinsically safe relay with 1A SPST-NO output and rated 5 A resistive at 125 V AC (40 °C) or 3 A (60 °C); 30 V DC resistive, driven by a 102-132V AC & 10-125V DC input.
It lets a switch or sensor in a hazardous location (Class I, Div 1, Groups A, B, C, D; Class II, Div 1, Groups E, F, G; Class III, Div 1 (Zones 0, 1, 20 and 21 in Canada)) control a load in the safe area.
It has 4 channels, each an isolated input and output.
Logic: standard or inverse, and instant or 2 s delay, selected for all channels (2-position DIP switch).
Response time: less than 50 ms, or a fixed 2 s delay (DIP switch).
It has DIN Rail/Panel Mounting and pluggable terminals.
