The 88826115 is a 17.5 mm DIN rail-mounted multi-function timer relay designed for industrial timing and control applications. It features 1 changeover relay output with an 8 A contact rating at 250 V AC/DC, AgNi (cadmium-free) contacts rated for 2000 VA/80 W, and supports multi-voltage operation from 12 to 240 V AC/DC at 50/60 Hz. The device offers seven timing ranges (1 s to 100 h) with ±0.5% temperature drift and ±10% display accuracy per IEC/EN 1812-1, along with multiple function options (A, At, B, C, H, Ht, Di, D, Ac, Bw) selectable via configuration. It includes screw terminals for wire connection (2 × 2.5 mm² without ferrule), LED status indication, and operates reliably across -20 °C to +60 °C with 105 electrical operations at rated load and 5×106 mechanical operations. Common applications include delay-on-energize, pulse generation, flip-flop control, and impulse timing in machinery, HVAC systems, and process automation.
