HCW-M421 Digital Relay Delay Timer Module 6V-30V 0.1-999min

The HCW-M421 Digital Relay Delay Timer Module is a compact, programmable timing board designed for users who need a reliable, adjustable delay control for relay-driven devices. It accepts a wide supply voltage from 6V to 30V and provides a configurable delay interval covering 0.1 to 999 minutes, allowing precise timing for on/off sequences in automation projects and equipment testing.

Configuration is handled through the module's digital controls, which allow users to set the required delay with fine resolution. The module drives a relay output suitable for switching external loads under the limits specified by the relay used on the board. Because of its broad input voltage range and extended timing span, the unit is suitable for battery-powered systems, industrial control panels, hobby electronics, and prototyping environments.

The HCW-M421 is designed for straightforward installation: standard connection points accommodate supply and load wiring, and its compact footprint makes it easy to integrate into existing assemblies or enclosures. The module's clear labeling and digital display or indicator (as provided on the unit) simplify commissioning and troubleshooting. This timer module provides a practical solution when a single-channel, adjustable delay relay is needed for timed control applications.
