HM series IO module

HM series I/O module is used to expand the I/O points of Hailin HD and D series DDC controller. This series has multiple models, can be adapted to input and output points of different signal types according to the requirements of the project site, and can be economically combined into a complete and independent local control system. It has RS485 communication port, supports

ModBus RTU and BACnet MS/TP protocols, it is also a standard I/O module that can be connected the third party’s system.
