Descriptions: Increase the supply anti-reversefunction. The use of opto isolated input and output,enhanced anti-jamming capabilit consumption. Set parameter after power for ever memories. Signal terminal voltage signal can be maintained for a longtime to ensure stability, industrial grade board, class PLC. Parameter: Size: 64.2mm*34.8mm*18.5mm. Relay Specification: AC 220V 10A or DC 30V 10A. Quiescent Current: 20mA Operating Current: 50mA Working voltage: DC 10 -16V (if other ranges can be customized) Signal voltage: DC 4V -20V (if other ranges can be customized) Life: about 100,000times Working temperature: -40 -85℃Selection: After power on,long press K12 seconds later into the select function mode,P1-1 to P1-4for choose. P1-1 operating modes:a signal to trigger relay, time is up, the relay disconnect users. You can set relay time T, click K2 the hundred digital tube starts flashing, then press K3, the hundred digital change. Click K2 ten digital tube starts flashing, then press K3, ten digit changes. Click K2 bit digital tube starts flashing, then press K3, single-digit change. Then click K2, digital pipe does not blink, then press the K3, shifting the decimal point, the decimal point in a bit indicates 0-999 minutes in ten represents 0 to 99.9 seconds without decimal point represents 0-999 seconds. Good choice, bringing the time setting is completed. Short press K1, enter function off line-tuning settings, trigger the default delay period is invalid, press K1, during the delay trigger active(re-timing), click on the K1, during the delay reset (timer turned off, the relay reset) pres
