LCD Digital Programmable Time Relay ST3P 12V/24V/220V + Socket
LCD Digital Programmable Time Relay – ST3P Series with PF083A Socket Base
Take precise control of your electrical circuits with the ST3P LCD Digital Programmable Time Relay. Featuring a clear digital display and four flexible working modes, this CE-certified relay is ideal for industrial automation, HVAC systems, lighting control, machinery timing, and general-purpose electrical projects. Compatible with 12V/24V/220V power supplies, it covers virtually any application.
Key Features
- Wide Time Range: 0.01 seconds to 99,990 hours — fine-grained control for any timing application
-
Four Working Modes:
- Power-on Delay – activates output after a set time upon power-up
- Delayed Disconnect – keeps output active then cuts off after a set time
- Cycle Delay – repeating on/off cycles for automated sequences
- Signal Off Delay – output remains active for a set period after signal is removed
- LCD Digital Display: Easy-to-read screen for straightforward programming and monitoring
- High Delay Accuracy: ≤0.5% — reliable and consistent timing performance
- Multi-Voltage Support: 12VAC/DC, 24V, and 220V options available (ST3P-1Z, ST3P-2Z, ST3P-2ZH models)
- Sealed Design: Protected against dust and minor contaminants for long service life
- CE Certified: Meets European conformity standards for safety and electromagnetic compatibility
- Includes PF083A Socket Base: Plug-in mounting for quick, tool-free installation and easy replacement
