Features: New upgrades to simplify, meeting the users' needs. Increase the power supply anti-reverse function. The use of opto isolated input and output, enhanced anti-jamming capability and consumption. The setting parameters can be memorized after power off. Signal terminal voltage signal can be maintained for a long time. To ensure stability, industrial grade PCB board. Notice: Relay output is passive contact without charge output, and it control the on and off of the line. Specifications: Display: LED Digital Display Timing Range(Settable): 0.1~99.9 seconds; 1~999 seconds; 1~999 minutes Working Voltage: AC 110~250V Signal Source: Low Level Efficient Output Capacity: Can Control the Load within DC 30V 5A or AC 220V 5A Static Current: 20mA Working Current: 50mA Working Temperature: -40-85 C PCB Size: 64 * 38 * 18mm / 2.52 * 1.5 * 0.7in (L * W * H) PCB Weight: 36g / 1.26oz Package List: 1 * Delay Timer Module 1 * Cable
