Littelfuse, Inc. Time Delay Relays THD1B410.5S

The THD1B410.5S is a time delay relay designed for delay-on-make operation, featuring a microcontroller-based timing circuit with a repeat accuracy of ±0.5%. It supports a time delay range from 0.1 seconds to 1000 minutes across six adjustable ranges. The relay can handle high load currents up to 20A and 200A inrush, allowing direct control of motors, lamps, and heaters without the need for a contactor. This solid-state relay is encapsulated for protection against shock, vibration, and humidity, ensuring reliability in various environments. It operates on input voltages of 24, 120, or 230VAC with a tolerance of ±20%, and has a power consumption of ,⧠2VA. The relay features a maximum mounting surface temperature of 90°C and is designed for surface mounting with a single screw. With a compact design and no moving parts, the THD1B410.5S is suitable for OEM applications, reducing labor and component costs while enhancing durability.
