?
With 4 pieces of 16 AD high speed difference, each responsible for 4 channel sampling, so it can measure negative input. 0-20mA this specification, can be measured from -15mA to 0 to +20mA, 0-30V this specification, can be measured from -20V to +30V. Each current input interface has protection, and can be connected with the transmitter. A 18 bit 250mV specification is used to measure 75mV signals.
1.Summary
Main characteristics
1: isolated RS485 interface, Modbus protocol voltage, current analog acquisition module. It can be networked with PLC, configuration software, text display and so on,
The utility model can be widely used for signal control of industrial field equipment.
2: wide working voltage: DC8V-30V, the power supply connection does not work. The original MC34063A switch power supply can work normally within 38V,
Measured 30V power consumption, 9mA, 24V power consumption, 12mA, 12V power consumption, 22mA, 8V, power consumption, 32mA.
3: operating temperature: -35+ 50.
4: on-chip reference voltage VREF=0.256V
1) accuracy: 0.256V±0.05%
2) drift: 15 ppm/
A low reference voltage means direct measurement of very small signals, such as 75mV DC shunts, bridge outputs, etc.. Thus, a precise amplifier can be omitted.
5: a variety of data format output:
1) 32 bit standard IEEE-754 floating point format, the data does not need any conversion, that is analog input value.
2) 16 bit unsigned integer output, data units A, mV.
3) 32 bit sampler digital output code, the user can be calculated by each LSB representative of the equivalent input.
6: sampling number of 16, 18, 24 bit, high resolution.
The single ended input type module uses a high-speed 16 bit AD sampler with a numerical range of -32768-32767.
7: installation: Standard 35mm rail installation.
