Specification: Working voltage: DC 5V, 12V, 24V (Optional) Working current: <80mA at 5V (<1mA when the relay is not operating), <35mA at 12V <1mA when the relay is not operating), <18mA at 24V (<1mA when the relay is not operating) Load capacity: -normally open port: DC 0-30V/10A, AC 0-250V/10A -normally closed port: DC 0-28V/10A, AC 0-125V/10A Working temperature: -20~60℃ (limit range -30~70℃) Size: 60*35*20mm / 2.36*1.38*0.79in Module function: Function F1:Power-on delay pull-in: After the delay of T1 from the start of power-on, the relay pulls in and sends a high-level pulse signal to the X1 interface at any time. This function resets and restarts. Function F2:The power-on delay is disconnected: the relay is closed when the power is turned on. After the T1 time is closed, the relay is disconnected, and a high-level pulse signal is given to the X1 interface at any time. This function is reset and restarts. Function F3:Self-locking relay mode: a high-level pulse signal is sent to the relay X1 interface, the relay is closed, and a high-level pulse signal relay is turned off. Function F4:Level trigger mode: When the power is turned on, the relay is disconnected, and a high level signal is sent to the X1 interface. The relay immediately picks up. After the X1 port signal disappears, the relay still pulls in. When the pull-in time T1 arrives, the relay turns off.
