Special Features

  • 【Relay Control Hub】Relay module can independently manage four 10A/250V AC or 10A/30V DC circuits, with isolation switches. Very suitable for multi device automation (such as smart farm irrigation systems, industrial conveyor belts), where synchronous control of motors, lights, and sensors is required.
  • 【Industrial Grade Durability】The relays can withstand extreme temperatures (-30 ° C to+75 ° C) and an input voltage range of 12-24V, and is compatible with trucks, RVs, and solar installations. 4 channel relay output module, with output contacts of 250A 10A. The input IN1, IN2, IN3, and IN4 signal lines are low and effective.
  • 【Indicator Light Prompt】The relay adopts a double-sided FR-4 circuit board design and is produced using surface mount technology. There is an isolation groove between the control area and the load area. The relay module has an action indicator light that lights up when it is engaged and does not light up when it is disconnected.
  • 【Easy Installation】 When there is a low-level signal at the signal input terminal of the relay, the common terminal and the normal terminal will conduct. The relay is equipped with 4 fixed bolt holes, each with a diameter of 3.1mm and a spacing of 68mm * 48mm, which is very convenient for installation and fixation.
  • 【Durable and Sturdy】The relay board is coated with a sturdy epoxy resin coating, which can prevent dust, moisture, and chemical corrosion (working range is -40°C to+85°C). The DC input voltage of the relay module can ensure the stable performance of trucks, ship equipment, or off grid solar installations.
