ST3P A-B Analogue On-Delay Timer Relay 12V DC (8-Pin, IME)

The ST3P A-B is the analogue alternative to a digital timer relay — a straightforward rotary dial marked directly in seconds rather than a thumbwheel or LED readout, which makes it fast to set and easy for any electrician on site to read without instructions. An internal jumper selects one of four ranges (0.1–1 second, 0–10 seconds, 0–60 seconds, or 0–6 minutes), so the same unit covers everything from a brief contact debounce to a multi-minute start-up delay. This 12V DC version powers up, begins counting the instant the coil is energised, and switches its contacts once the dial's set delay elapses, with UP and ON LEDs on the fascia showing timing-in-progress and output-energised status at a glance. Its 8-pin octal base is common across the ST3-series family, so it fits standard relay sockets and rack-mounted control panels without any base adaptation. It's suited to 12V DC control circuits in vehicles, solar and battery-powered systems, and low-voltage automation panels needing a simple, field-visible on-delay timer rather than a digital display.
