FAQ

Q: What is a 'hybrid' delay relay?
A: It combines an electromechanical relay (for robust switching) with integrated solid-state electronics (for precise timing) in one sealed package.

Q: How is the delay time programmed?
A: Typically via external resistor/capacitor values or dedicated programming pins. Refer to the datasheet for specific programming methods compatible with the LEACH TDH6050 footprint.

Q: Can this relay handle higher currents like an Intermediate Power Relay?
A: No, its 1A rating is for signal-level or low-power switching. The primary advantage is integrated programmable timing in harsh environments.

Q: Is it suitable for New Energy applications?
A: Its precision timing and robustness can be applicable in certain New Energy Relay scenarios like battery management system sequencing, provided voltage and current ratings align.
