SMR-D010

The SMR-D010 is a dual relay timer module designed to allow low voltage control of high power loads with an adjustable delay function. It is suitable for applications requiring reliable timing control and fail safe operation, such as access control systems, lighting control and equipment protection.

Once triggered, the relays remain active for a preset delay period before automatically returning to their default state. This allows temporary override or delayed shutdown functions to be implemented within a system.

Designed for dependable and fail safe operation, the SMR-D010 provides a simple and effective solution for applications requiring controlled switching together with adjustable timing functionality.

Typical Applications
– Emergency door control, temporary override to keep doors unlocked for safe egress, followed by automatic reset
– Lighting control, delayed switch off after motion detection
– Equipment protection, controlled shutdown after fault or alarm conditions
– Security systems, timed arming, disarming or delayed lockdown functions

Key Features
– Dual independent relays, Form C (SPDT), NO, NC and COM contacts
– 10A switching capacity suitable for motors, lighting and solenoids
– Independent channel operation for control of two separate circuits
– Adjustable delay timer from 10 seconds to 75 minutes
– Delay setting via 5 position DIP switch
– Low power consumption, suitable for battery-powered systems

Trigger Interface
– Input terminals: Trigger + (positive) and Trigger – (negative)
– Compatible with sensors, access control systems, manual switches and controllers
– Trigger input activates the relay outputs and starts the delay timer
