DESCRIPTION

The 88866300 is a DIN rail-mounted timer module featuring 2 changeover relays with 8A nominal rating and screw terminal connections. It supports multiple timing functions (A, Ac, At, B, Bw, C, D, Dt, H, Ht) with 7 selectable timing ranges spanning from 1 second to 100 hours, and operates on 12 VAC/DC supply. The device delivers high timing accuracy of ±0.5% with minimal temperature drift (±0.05%/°C) and voltage drift (±0.2%/V), ensuring reliable performance across varying environmental conditions. With a compact 22.5 mm DIN rail width, LED status indicator, and compliance with IEC/EN 61812-1 standards, this timer is ideal for industrial automation, process control, and relay switching applications requiring precise time-delay functionality.
