Description The Selec 800 SQ-A is a compact and highly reliable On Delay/Interval Timer, designed for precision timing control in automation systems. With selectable time ranges of 3 / 10 / 30 / 60 seconds or minutes, and a fine 0.3-second resolution, this timer is perfect for applications demanding exact delays. It offers excellent accuracy with a setting tolerance of ±5% of full scale and repeat accuracy of ±0.5% or 50ms—whichever is greater. Its SPDT relay output rated at 5A @ 250V AC or 24V DC ensures reliable switching. Operating on 230V AC or 24V AC/DC, and measuring just 22.5mm, it easily mounts on DIN rails, making it ideal for space-sensitive control panels. How to Install the Selec 800SQ-A Timer Step-by-Step Installation Guide: Power Off: Always turn off the main power supply before installation to avoid electric shock. Mounting: Mount the 800SQ-A securely on a standard DIN rail inside a control panel (22.5mm slot width). Wiring: Connect the power supply terminals as per rated input (230V AC or 24V AC/DC). Connect the control/load circuit to the SPDT (1 C/O) relay terminals. Set Time Mode: Select the desired mode (On Delay / Interval) using the selector switch. Adjust Time Range: Rotate the dial to set the required delay range (3 / 10 / 30 / 60 sec/min). Verify: Double-check all connections for correctness. Power On: Switch on the power supply and test the functionality as per application needs. DATA SHEET
