描述

The 88865105 is a Chronos 2 electronic timer featuring a single DTDP relay output rated at 8 A and 250 V (10 A UL), designed for multi-function or mono-function timing control in industrial automation. The timer offers seven selectable timing ranges from 0.1 s to 100 h with ±0.5% repetition accuracy and supports multi-voltage operation (24 V DC/AC or 24–240 V AC depending on configuration). It includes temperature drift of ±0.05%/°C, voltage drift of ±0.2%/V, and a minimum pulse duration of 30 ms (relay version) or 100 ms under load. The device features volt-free contact input with optional 3-wire PNP sensor control (maximum residual voltage 0.4 V), LED status indicators, and screw or spring terminal options. Operating temperature range is -20 °C to +60 °C (storage to -30 °C), with IP 20 terminal block protection and IP 40 casing protection. It is commonly used in delay-on-make, timing-on-make, pulse output, and flip-flop applications across industrial control, HVAC, and machinery automation systems.
