Product Description
The numerical transmission and control signals of industrial automation instruments are being upgraded
from traditional 4-20mA analog signal to industrial fieldbus with digital communication functions. HART fieldbus
has the function of digital communication and it is compatible with 4~20mA analog signal, which is widely used
now.
Microcyber HART Modem provides two kinds of PC interface. HM105-RS232 is a converter between HART
bus signal and RS-232 serial signal.HM105-USB is a converter between HART bus signal and USB virtual serial
signal.
Voltage-mode modem signal
Compliance with HART (FSK) Physical Layer Specification
Transformer isolation to avoid grounding effect
Low power design without external power supply
Two Choices with USB Port and Serial Port
USB HART signal modem can supply external power
The output amplitude of RS232A HART signal modem is adjustable
