Product Description

The DL-20-ET Device is a versatile industrial sensor unit with 4 analog/digital inputs and 2 relay outputs, designed to interface directly with up to 2 DL-20-SNB Modules. It operates on 24VDC (±10%) and supports Modbus RTU over RS-485, with an operational temperature range of -20°C to 60°C. Paired with the DL-20-JB Controller, this system enables centralized monitoring in manufacturing and energy sectors, featuring a 3.5-inch LCD display and 5000mAh backup battery. The DL-20-SNB Module extends functionality with wireless LoRa connectivity (1km range) and 2 additional I/O ports, though its 2000mAh battery limits standalone runtime. Key advantages include modular scalability and IP65-rated durability, while limited onboard processing requires reliance on the DL-20-JB for data analysis. All components maintain compatibility for harsh environments with vibration resistance up to 5G.
