Module RS-485 Modbus RTU 2 kênh đầu vào bộ đếm/tần số (Counter/Frequency) ICP DAS M-7080B-G CR


  • 2 Counter/Frequency Inputs
  • Supports 32-bit Counter
  • Isolated or Non-isolated Input
  • Programmable Alarm Output, Digital Filter and Threshold Voltage Level
  • Maximum Frequency of up to 100 kHz
  • Built-in Dual Watchdog


The M-7080(D)/M-7080B(D) offers 2 high-speed counter or frequency input channels and 2 digital output channels. Two types of digital input are provided one for isolated input, and the other for non-isolated input. The isolated input provides 3750 Vrms isolation voltage and the non-isolated input provides a programmable threshold voltage level. The built-in digital filter is valid for both non-isolated and isolated input and can filter out noise where the high/low pulse width is smaller than the minimum high/low width of the digital filter. The maximum count is up to 32-bit and the maximum frequency is up to 100 kHz.

The module also provides programmable alarm output with non-isolated open collectors. The M-7080(D)/M-7080B(D) supports Modbus RTU and DCON protocols, which can be configured via software, and all hardware specifications are the same as the the I-7080(D)/I-7080B(D). The function of The M-7080B(D) is the same as that of the M-7080(D), except that The M-7080B(D) provides a virtual battery backup function in counter mode.
