The SSAC TSD2625 is a two-wire DC adjustable timer designed to work with 12 or 24V DC low voltage systems. It is designed to replace mechanical timers, providing greater accuracy and repeatability in many timing and switching applications. With adjustable on-times between 0.1 sec (100msec) and 10 hours, the TSD2625 can be used in many applications ranging from basic on/off control to precise metering, sequencing, or PID control. The TSD2625 is self-powered and compatible with all conventional SSAC relays. It features adjustable time reset, non-volatile memory, manual override, and a wide range of input options, including an S&S terminal for sensor control.
