2 Channel 5V/12v/24v Relay Module with Optical Coupling Isolation Support high and Low Level Trigger Two-Way(12v)

relay1, the module USES the original pine relay, normally open interface maximum load: ac 250 v / 10 a, dc 30 v / 10 a.2, USES the original patch optical coupling isolation, driving ability is strong, stable performance; Trigger current 5 ma;3, modules, working voltage 12 v4, module can be set through the jumper wire high level or low level trigger;5, fault-tolerant design, even if the control line is broken, relay will not move;6, power indicator light (green), relay status indicator light (red)7, human interface design, all interface can be directly by terminal connection leads, is very convenient8, module size: 41 mm to 50 mm * * 18.5 mm (length * width * height)9, is equipped with four fixed bolt hole, hole is 3.1 mm, spacing of 44.5 mm * 35.5 mmModule interface:The positive (voltage, DC + 1: to connect power to the 12 v) according to the requirements of relay2, DC - : connect power cathode3 IN1:1 road signal triggering end, can be set high or low level control relay and off3, IN2: two-way signal trigger side, can be set high or low level control relay and off
