Was: 7.50
Price: 4.12

Description Maximum load AC 250V 10A DC 30V 10A The chip optocoupler isolation strong driving ability stable performance trigger current 5mA Working voltage is 24V Every 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 4 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 73mm x 50mm 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 2 DC Connect the power negative pole 3 IN1 IN4 According to the setting of each way the corresponding relay operating can be controlled by high or low level Relay output there is a 12 wire interface all interfaces can be directly connected to lead to facilitate user use 1 NO1 NO4 Relay normal open the relay suspends before pulling in and then short connect with the COM 2 COM1 COM4 Relay common interface3 NC1 NC4 Relay normal close short connected with COM before pulling inand suspended after pulling in High and low level trigger option 1 S1 S4 is the high level trigger selection of relay 1 Channel 4 Channel 2 When COM is short connected with LOW the corresponding relay is LOW level trigger while when COM is short connected with high end is high level trigger Package
