PTDNC04 is a PT100/PT1000 RS485 collector developed and produced by eletechsup. It uses low-cost components and reasonable and ingenious design to achieve cost-effective PT100/PT1000 sensor temperature and resistance value collection.
PTDNC04 PT100/PT1000 RS485 Acquisition module Description:
Power supply voltage: DC 6~25V
Working current: 20MA
MODBUS RTU protocol, 03 read command, 06 or 16 write command.
Serial port baud rate: 1200-115200,9600 (default), N, 8, 1
By modifying the 485 address, up to 247 modules can be cascaded (please use RS485 repeater for more than 16)
Can read temperature and PT100/PT1000 resistance value
Applicable sensor: PT100/PT1000 3-wire or 2-wire sensor
Temperature measurement range: A version -40℃ to +220℃; B version -40℃ to +500℃. It is recommended to choose a version with a smaller range within the measurement range.
Temperature measurement accuracy: 1%, if the temperature deviation is too large, please recalibrate
