Overview

The Macromatic THR-1 Time Delay Relay (SKU: TH41261-37J) is a microprocessor-based timing control device engineered for industrial automation. This encapsulated relay delivers precise time-based control with a 30A Single Pole Double Throw (SPDT) output, enabling direct switching of heavy loads without requiring a separate contactor. The THR-1 series supports multiple time delay functions including On Delay, Off Delay, Single Shot, Watchdog, and Interval, with timing ranges from 0.05 seconds to 100 hours. Users can configure the timing function as either adjustable via onboard potentiometer or fixed at the factory. The relay operates on universal input voltages from 24-240V AC and 12-125V DC, making it compatible with diverse control systems. Encapsulated in a compact 2" x 3" enclosure, the THR-1 is panel-mounted with a single bolt and features quick-connect terminals for simplified wiring. Designed for harsh industrial environments, this relay provides reliable operation with superior accuracy and repeatability.

HRDB121

The HRDB Series combines an electromechanical, relay output with microcontroller timing circuitry. The HRDB offers 12 to 230V operation in five options and factory fixed, external, or onboard adjustable time delays with a repeat accuracy of ±0.5%. The isolated output contact rating allows for direct operation of heavy loads, such as compressors, pumps, blower motors, heaters, etc. The HRDB is ideal for OEM applications where cost is a factor. Operation (Delay-on-Break): Input voltage must be applied before and during timing. Upon closure of the initiate switch, the output relay energizes. The time delay begins when the initiate switch is opened. The output remains energized during timing. At the end of the time delay, the output de-energizes. The output will energize if the initiate switch is closed when input voltage is applied. Reset: Reclosing the initiate switch during timing resets the time delay. Loss of input voltage resets the time delay and output.
