Electronic timer with 365-day astro operation
The TORK DZS400BP is an electronic timer designed for automated lighting and load control across a full year. It offers four independent channels and a 365-day astro scheduling mode that tracks sunrise and sunset times automatically. The unit suits commercial and industrial installations where daily or seasonal load changes need reliable, hands-free operation.
Thermals, noise and power draw in normal use
The timer mounts in a plastic NEMA 3R enclosure rated for surface installation and outdoor exposure. It draws minimal control power while switching loads up to 20 A at 120/208 to 240/277 V AC. Solid-state switching and a sealed enclosure keep operating noise negligible and thermal output low during continuous duty.
Specification that decides fit: 99 events across
The timer stores up to 99 programmable events shared across its four channels, with each on/off action consuming two events and each pulse action consuming one. Pulse duration is adjustable from 1 to 99 seconds. Buyers who need more than 99 total events or more than four independent circuits should consider a different controller.

Questions about this item
How do I mount the TORK DZS400BP timer and what wiring step is often missed?
Surface-mount the plastic NEMA 3R enclosure, then connect line voltage between 120 and 277 V AC to the single-pole SPDT contacts rated for 20 A; the step installers skip is verifying the 1 HP at 120 V or 2 HP at 240 V motor-load rating matches the connected equipment.
What maintenance will the TORK DZS400BP need over its service life?
Replace the internal backup battery when the display dims or programming is lost after a power outage; the SPDT relay contacts are rated for 20 A resistive load and should be inspected periodically for pitting if switching inductive loads near the 1 HP / 2 HP ratings.
What is the first limitation I will hit when running the TORK DZS400BP continuously?
The 99-event memory fills first — each on/off action consumes two events and each pulse action consumes one, so complex 365-day schedules with many pulses can exhaust the event pool before the 1-minute minimum setting or 20 A contact rating becomes a constraint.
