{"title":"8-Channel Isolated Analog Data Acquisition Module","handle":"8-channel-isolated-analog-data-acquisition-module","url":"/products/8-channel-isolated-analog-data-acquisition-module","description":"The 8-Channel Isolated Analog Data Acquisition Module is an industrial-grade 12-bit ADC with RS485 communication, designed for reliable multi-channel voltage and current measurement in demanding environments.\n\nEach channel is independently configurable for different input ranges, and the module supports standard 2-wire, 3-wire, and 4-wire sensor connections. Communication and input/output are optically isolated to 1500VDC, protecting your system from interference and electrical faults. The module uses the standard Modbus RTU protocol for easy integration with PLCs, SCADA software, industrial PCs, and OPC systems.\n\nKey Features\n\n\n8 Independent Channels – Each channel can be configured for a different input range\n\nMultiple Input Ranges – Supports 0–5V, 1–5V, 0–2.5V, 0–20mA, and 4–20mA (factory default: 4–20mA)\n\n12-Bit Resolution – Collection accuracy of ±1‰\n\nOpto-Isolated RS485 – 1500VDC isolation voltage for reliable industrial communication\n\nModbus RTU Protocol – Standard industrial protocol for easy integration\n\nFlexible Sensor Support – Works with 2-wire, 3-wire, and 4-wire sensors\n\nWide Power Supply – 12–30VDC input with reverse-polarity protection\n\nSoftware Watchdog – Automatic recovery from communication faults\n\n\nSpecifications\n\n\nInput Channels: 8× single-ended analog\n\nInput Types: Voltage and current\n\nSampling Rate: 1400 sps total (50 sps per channel)\n\nInput Impedance: 10 MΩ (voltage), 249 Ω (current)\n\nBaud Rate: 1200–115200 bps\n\nMax Transmission Rate: 180 reads/sec at 115200 bps, 24/sec at 9600 bps\n\nPower Consumption: 0.5W rated at 24VDC\n\nOperating Temperature: −40°C to +80°C\n\nStorage Temperature: −40°C to +85°C\n\n\nIdeal For\n\nIndustrial monitoring and SCADA systems\nMulti-sensor data acquisition\nPLC and OPC integration projects\nEnvironmental and process monitoring\n\n\nPackage Contents\n\n1× 8-Channel Isolated Analog Data Acquisition Module\n\n\nResources\n\nProduct Instruction (PDF)\nConfiguration Software (RAR)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2657,"title":"Default Title","sku":"DF-DFR0853","price":136.57,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":1,"option1":"Default Title"}]}
