Data Acquisition


  • Source-type Digital Output with Overload Protection
  • Configurable Power-on Value and Safe Value Settings
  • Short Circuit Protection
  • Overload and Overvoltage Protection
  • Built-in Dual Watchdog


The M-7045 series offers 16 digital output channels, each of which features photocoupler isolation. The M-7045 supports source-type output, while The M-7045-NPN supports sink-type output, and both are equipped with short circuit protection. The M-7045D/M-7045D-NPN provides 16 LED indicators for channel status monitoring.

The M-7045(D)/M-7045(D)-NPN supports Modbus RTU and DCON protocols, which can be configured via software. There are also options for configuring power-on and safe values. 4 kV ESD protection, 4 kV EFT protection, 3 kV surge protection for power input, and 3750 VDC Intra-module isolation are standard, and all hardware specifications are the same as the I-7045(D)/I-7045(D)-NPN.
