1. supply (two power supplies cannot be powered at the same time): Power supply 1, DC 6.5-25V; Power supply 2, DC 5V. 2. Working current: (Normal Mode) standby current 41mA, working current 83mA; (Energy-Saving mode) Standby current 7mA, working current 44mA. 3. There are three input control port: forward control(FWD), reverse control(), and stop control(STOP).Two input trigger modes, Low-Pulse trigger mode, Low-Level trigger mode. 4. Delay time: 0.1-999.9 seconds, 1-9999 seconds, 1-9999 minutes.Cycle times: no cycle, 2-99 cycles, always cycle. 5. Three indicators: forward indicator(F LED), reverse indicator(R LED), stop indicator(S LED). 6. Relay load current, recommended less than 5A. 7. This is a multi-function DC/AC motor forward and reverse controller with multiple control modes. Many control functions can be derived through reasonable settings.
