MicroLink-HM HART Protocol Modem

Microflex, 101-0035, MicroLink-HM HART Protocol Modem + Modbus Accumulator, RS-485 InterfaceThis is the RS-485 MicroLink-HM, a managed HART interface that can be used as a primary or secondary HART master - 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. See 101-0029 for the MicroLink-HM with RS-232 interface.FeaturesCan be used as a standard HART protocol modem or HART to modbus accumulatorRS-485 port allows multiple modems on the same networkDIN Rail Mounted (35mm)Wide 5 to 30 Vdc supply rangeLED provides HART communications statusCompatible with USB to RS-485 serial converter cablesRS-485 port can be set to standard baud rates from 1200 to 57600 O, E, N parityComplies with HART physical layerTransformer isolation simplifies loop connections and eliminates grounding effectsUse standard modbus commands to read HART device variable dataIncludes HM Configuration app and HART device addressing appIncludes PACTware and Microflex Generic HART DTM-6 on a CD.
