描述

The 88866305 is a DIN rail-mounted timer module featuring 2 changeover relays with 8A nominal rating per relay, designed for industrial control applications. It supports multiple timing functions (A, Ac, At, B, Bw, C, D, Di, H, Ht) with 7 selectable timing ranges spanning from 1 second to 100 hours, and operates on multi-voltage supply options including 24 V DC or 24–240 V AC. The timer delivers high precision with ±0.5% repetition accuracy, temperature drift of ±0.05%/°C, and voltage drift of ±0.2%/V, while featuring screw terminals, LED status indicator, and AgNi (cadmium-free) relay contacts rated for 250 VAC / 8 A resistive breaking capacity. With mechanical life exceeding 10 million operations and electrical life of 105 operations at 8 A 250 VAC, this timer is ideal for automation systems, process control, and industrial switching applications requiring reliable timing and relay switching functionality.
