Product testing experience:
Although it uses the LM324 op amp as the front-end circuit like other eletechsup PT100 collectors, it uses a more ingenious and reasonable signal processing design, coupled with a more accurate ADC chip, which allows it to achieve higher-precision measurements while keeping the cost unchanged. Its measurement accuracy is more than 20% higher than that of PTA8C04 PTA8D08 PTA8E16.
PTDNC04 PT100/PT1000 RS485 Acquisition module Description:
Power supply voltage: DC 9V 12V 15V 24V(6-25V)
Working current: 18-20MA
MODBUS RTU protocol, 03 Read Command, 06 or 16 Write Command.
Serial port baud rate: 1200,2400,4800,9600 (default), 19200,38400,57600,115200,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
Dimensions: 72 X 46 X18MM (board only), 79 X 49 X40MM (with shell)
Weight: 32g (board only), 78g (with shell)
