Industrial timing relay
The Macromatic ISDUR4 is a general purpose relay designed for control circuits that require a fixed two second delay on energisation. It accepts a wide control range from 10 to 125 volts DC or 102 to 132 volts AC and switches up to 5 amps at 120 volts AC or 30 volts DC. A built in LED gives immediate visual confirmation of coil status. The unit mounts on DIN rail or a flat surface and connects through screw terminals.
Replaces basic contactors
This relay upgrades simple contactors or timers that lack an integrated delay and local indication. The fixed 2.00 second delay suits sequencing tasks such as motor stagger start or alarm hold off without an external timer module. The 50 millisecond response time ensures the output follows the control signal cleanly once the delay expires. It is not suited for applications needing adjustable delay ranges or multiple timing functions.
Panel mount integration
The 2.6 inch height and 2.36 inch width fit standard DIN rail enclosures leaving space for adjacent modules. Screw terminals accept solid or stranded wire for secure connections in vibration prone environments. The 5.0 VA burden is low enough for most control transformers. Hazardous location switches and sensors can be wired directly to the input. Buyers who need higher contact ratings or multiple poles should specify a different relay.

Questions about this item
What DIN rail or surface dimensions does the 2.6 in by 2.36 in relay need for mounting?
The relay body measures 2.6 in tall and 2.36 in wide and mounts on standard DIN rail or a flat surface using the integral clips or screw holes.
How do I wire the screw terminals and which coil voltage range applies?
Connect control voltage to the input terminals — 10 to 125 V DC or 102 to 132 V AC — and the load to the output screw terminals; the fixed 2.00 s delay and 50 msec response are internal.
When should the relay be replaced if it switches 5 A at 120 V AC or 30 V DC?
Replace the unit when the LED indicator fails to show coil status, contacts stick, or the 2 s delay drifts beyond spec after extended 5 A switching cycles.
