Data Acquisition


  • 4 Form A and 4 Form C Signal Relay Outputs
  • Configurable Power-on Value and Safe Value Settings
  • Built-in Dual Watchdog


The M-7068/M-7068D provides 4 Form A signal relay output channels and 4 Form C signal relay output channels, while The M-7069/M-7069D provides 4 Form A power relay output channels and 4 Form C power relay output channels. The M-7068D/M-7069D includes 8 LED indicators for channel status monitoring.

The M-7068(D)/M-7069(D) 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, 4 kV EFT and 3 kV surge protection are also provided to enhance noise protection capabilities in industrial environments. The M-7068(D) is the ideal solution for small signal-switching applications, while The M-7069(D) is the perfect solution for high-power applications.
