The 88827503 (MURc3) is a multi-function DIN rail-mounted timer featuring one changeover relay with an 8 A nominal rating and spring terminals for flexible wiring. It supports multiple timing functions (A, Ac, At, B, Bw, C, D, Di, H, Ht) across seven selectable ranges from 1 second to 100 hours, with a repetition accuracy of ±0.5% and temperature drift of ±0.05%/°C. The device operates on 12–240 VAC/DC supply at 50/60 Hz with an operating range of 85–110% nominal voltage (85–120% for 12 V), consuming up to 32 VA at 240 VAC or 1.5 W at 240 VDC. The relay output is rated for 250 VAC / 8 A AC resistive or 30 VDC / 8 A DC resistive, with a minimum breaking current of 10 mA at 5 VDC and electrical life of 105 operations. The timer is housed in a compact 17.5 mm DIN rail case with an LED status indicator, 3-wire PNP sensor compatibility, and operates reliably across -20 °C to +60 °C. Common applications include industrial automation, process control, and equipment sequencing where precise timing and relay switching are required.
