บอร์ดรีเลย์ Relay 12V 1 Channel Isolation High And Low Trigger บอร์ดรีเลย์ 12V 1 ช่อง ป้องกันไฟช็อตแบบ Isolation สามารถเซตให้ทำงานได้ทั้งโหมด Active High หรือ Active Low ข้อมูลบอร์ดรีเลย์ Relay 12V 1 Channel Isolation High And Low Trigger 1. the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A; 2. using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA; 3. the module voltage is 12 V; 4. the module can be set to high(3.3-5V) or low(0V) triggered by jumper; 5. fault-tolerant design, even if the control line is broken, the relay will not operate; 6. the power indicator (green), relay status indicator (red) 7. interface design humane, all interfaces can be connected directly via terminal wiring leads, very convenient 8. module size: 50mm * 26mm * 18.5mm 9. has four mounting bolts holes, hole 3.1mm, 44.5mm * 20.5mm pitch Module interfaces: 1. DC +: positive power supply (voltage required by the relay) 2. DC-: negative power connection 3. IN: can be high or low level control relay Relay outputs: 1. NO: normally open relay interface, the relay before the vacant after the pull shorted with COM 2. COM: Common Interface Relays 3. NC: normally closed relay interface relay shorted with COM ago, after the pull-vacant
