Allow Building management systems and other ModBus Master devices to communicate to any HTP gas fired appliance using the ModBus protocol. Send system commands and collect data from up to various multiple devices on the bus using one RS-485 port on the Building Management System. With the HTP ModBus adapter you will save time by monitoring many appliance parameters including temperatures, status, and fault conditions from one simple connection to the appliance.

Features

• System cost savings - collect sensor, status, and fault data and control the appliance directly using one connection. Eliminates having to use expensive external sensors and I/O hardware to measure the same parameters externally.
• Easy to set up - Use the display already located on the appliance to set all Modbus communication parameters. Termination resistors are included in each unit and are enabled by default. Simply remove a jumper to disable the resistor.
• Easy Interface - developed for easy interface to BMS or Industrial control systems. Commonly used discrete registers are available singly and also grouped into word registers for easy programming. Complete register list and programming examples included with each unit.
• Easy troubleshooting - by using built in LED’s to monitor communication both on the Modbus as well as to/from the appliance.
