DDC Field Controller
DLI-5.4.8.2
supports independent communication and can meet general and special applications. It comes with two open communication protocols: Bacnet MSTP and Modbus RTU. DLI-5.4.8.2 can control and manage remote controlled devices via field bus connections to satisfy general and special applications. It can be used either as a simple I/O monitoring module or as a field controller with specific functions.
- Multi-protocol DDC controller, supporting BACnet MS/TP and Modbus protocols via RS-485;
- Standard protocols, compatible with various configuration software;
- 8 input channels configurable for voltage input, current input, digital input, resistance measurement and NTC10K input measurement;
- 5 input channels for isolated digital input;
- 2 output channels configurable for voltage output, current output and digital output (for external relay control);
- 4 output channels with relay output;
- 8 input channels adopt high-speed 12-bit A/D sampling for analog input signals;
- 2 output channels adopt high-speed 16-bit D/A conversion to generate analog output signals;
- Modular programming, WYSIWYG;
- Built-in multiple commonly used application algorithms
