BESTEP 2 Channel 24V Relay Module High And Low Level Trigger For Auduino

Description The module uses genuine quality relay normal open interface maximum load AC 250V 10A DC 30V 10A The chip optocoupler isolation strong driving ability stable performance trigger current 5mA Working voltage is 24V Each channel of the module can be set up by high jumper or low level trigger Fault tolerant design even if the control line is broken the relay will not act Power indicator green 2 relay status indicator red The interface design is humanized all interfaces can be directly connected through the terminals so it is very convenient Module size 50mm x 42mm x 18 5mm length x width x height There are 4 fixed bolt holes holes 3 1mm spacing 67mm x 44 5mm Module interface 1 DC Connect the power positive pole voltage according to relay 24V 2 DC Connect the power negative pole 3 IN1 IN2 According to the setting of each way the correspondingrelay operatingcan be controlled by high or low level Relay output there is a 6 wire interface all interfaces can be directly connected to lead to facilitate user use 1 NO1 NO2 Relay normal open the relay suspends before pulling in and then short connect with the COM 2 COM1 COM2 Relay common interface3 NC1 NC2 Relay normal close short connected with COM beforepulling inand suspended afterpulling in High and low level trigger option 1 S1 S2 is the high level trigger selection of relay 1 Channel 2Channel 2 When COM is short connected with LOW the corresponding relay is LOW level trigger w
