This relay control panel, compatible with multiple operating modes, using three digits LED display, the program of intelligent control, time relay/delay function for automatic control, product testing, DIY and other areas. 

Features: 
The modes setting values can be memorized after power off, convenient for use.
Digital tube socket mounting module can be removed directly.
Voltage detection can set the calibration: -0.3V-0.3V.
Automatically turn on the timer after power on(short external switch input terminals).
Set arbitrarily timing/delay time and execution frequency, the single loop can execute multiple times.
P-1, P-2 model can be an external pulse signal(rising) or switch to trigger the relay.

Modes Display:
P-1: Timer Relay(0-999s or 0-999m)
P-2: Delay Timer Relay(0-999s or 0-999m)
P-3: Voltage Control Relay(Control the Load on/off)
P-4: Voltage Control Timer-A(Release First)
P-5: Voltage Control Timer-B(Close First)
P-6: Voltage Over Limit Operating Mode
P-7: Voltage Over Limit Control Timer Relay
P-8: The LED Display Automatically Close Setting
