DRF series ModBus control voltage regulating controller
DRF series multi-channel voltage regulating controller adopts RS485 Mod-Bus control and Modbus RTU communication protocol. This controller can be used with the random-on type solid state relay to realize the function of voltage regulation and control 12 channels of SSR independently. The address can be set from 1-8. The address can be set from 1-8, supporting multiple baud rate and checking bit setting. The default baud rate is 9600 with no check and 2 stop bits.

NOTES
1.Default baud rate 9600, 8 data bits, no check, 2 stop bits. It can be modified by ModBus.
2.DRF communication protocol adopts standard Modbus RTU.
3.In order to reduce the external interference, it is recommended to use twisted pair or shielded wire as the control wire of RS485.
4.Please use random-on solid state relay to ensure the system stability.
5.Whether the load is lamp or fan, please consult with the sales people to get the support of selecting the SSR and heat dissipation solution.
