Microflex 101-0035 MicroLink-HM HART Protocol Modem + Modbus Accumulator, RS-485 Interface

The MicroLink-HM RS-485 is a managed HART modem that can be used as a primary or secondary HART host interface - eliminating the need for external carrier detect (CD) monitoring and request-to-send (RTS) control. It can also be configured to continuously poll up to 16 HART devices, filling internal Modbus registers with variable values. The variable values can then be read as 16-bit signed integer or single precision floating point using Modbus-RTU commands. Configuration is saved in Modbus registers allowing Modbus commands to be used for configuration - or use the free included HM Configuration app.
