The 88826155 is a 17.5 mm DIN rail-mounted multi-function timing relay designed for industrial control applications requiring flexible timing and switching capabilities. It features 1 changeover relay output with an 8 A contact rating at 250 V AC/DC, supporting multiple timing ranges from 1 second to 100 hours with 0.1 s + 100 h base timing and ±0.5% temperature drift accuracy. The device operates on multi-voltage supply (12 V to 240 V AC/DC depending on version), with a maximum absorbed power of 0.6 W at 24 V AC/DC and 1.5 W at 230 V AC, and includes spring terminals for flexible wire connections (1.5 mm² flexible, 2.5 mm² rigid). It delivers 105 electrical operations at 8 A 250 V resistive and 5×106 mechanical operations, with a minimum pulse duration of 30 ms (relay version) and maximum reset time of 100 ms. Common applications include process automation, equipment sequencing, and industrial control systems requiring reliable timing and switching with multi-voltage flexibility.
