ITEM NAME:5v 1 Channel SSR Solid-state Relay High Level Trigger 2a 250v Precise for A D5T5 5v 1 Channel SSR Solid-state Relay High Level Trigger 2a 250v Precise for A D5T5 5V Low Level Solid State Relay Module with Fuse Solid State Relay 250V 2A Size: 25 * 34 * 25 (L * W * H) Net Weight: 13g Input power: 5V DC (160MA) The input control signal voltage:ï ¼Å¸(0-1.5V state low level relay ON) (2.5-5V state high level relay OFF) Blue KF301 terminal access control line more convenient. Color:black Material:Metal Module Interface: Input section: DC +: Connect the power supply positive (according to the relay voltage) DC-: Connect the power supply negative CH: relay module signal trigger terminal (low level trigger active) High and low meaning: High-level trigger refers to the signal trigger side (IN) and the power supply there is a positive voltage between the positive, usually with the power of the positive and trigger connected to a trigger mode, when the trigger side has a positive voltage or trigger Voltage, the relay is pulled. Low-level trigger refers to the signal trigger terminal and the power supply negative voltage between the OV, or the trigger side of the voltage than the power supply voltage is lower, low to trigger the voltage, so that the relay pull, usually The negative side of the power supply is connected to the trigger terminal and is triggered by the relay. Electrical parameters: Voltage Version Quiescent Current Operating Current Trigger Voltage Trigger Current 5V 0mA 12.5mA 0-1.5V 2mA product manual: Module power supply: the power must be DC, the voltage and the relay voltage to match Package Includes : 1 x Solid State Relay Module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm..5V Low Level Solid State Relay Module with Fuse Solid State Relay 250V 2A.
