12V 24V DC LED Display Digital Voltage Meter Test Control Relay Timer Time Delay Switch Module with Case

Features:LED digital display, mounting boss on the case, convenient and simple for user's needs.Procedures for intelligent control, realize over-voltage/under-voltage function.Wide range of working power: DC 8-35V; the voltage detection range is DC 0-99.9V.Adjustable input voltage detection sensitivity: 0.1-0.9s.The relay output timing range is 0-999s.To ensure stability, use industrial grade PCB board.Working Modes Selection:P-1: Delay Setting(set the delay time and pull time);P-2: Voltage Detection Control(detect the voltage to control the relay operation, initial release);P-3: Voltage Detection Control(detect the voltage to control the relay operation, initial pull);P-4: Over-voltage/under-voltage Control(voltage limit alarm).
