Ovation™ HART 8-Channel Analog Output Module
Features
• Eight multiplexed analog output channels, 4
20mA generated by the HART Analog Output
module
• Channels are not isolated from one another and
share a common external +24 VDC auxiliary
power supply and ground
• 16 MHz micro-controller for A/D and D/A
conversion and HART interface control
• 14-bit A/D converter shared amongst 8 output
channels
• Array of switches superimpose transmitted
signals upon each 4 - 20 mA analog outputs to
the output device
• Interfaces through a low-level frequency, shift
keyed sine wave signal that is superimposed on
the 4-20mA signal
• Directly links the Ovation control system to
intelligent field devices
• Uses the AMS Suite, Device Manager for
information collection and maintenance
• Software configurable I/O bus communication
time-out period
• 1000 VDC/RMS electrical isolation between field
and logic circuitry
• Electronic ID information stored on logic board
EEPROM (Electrically Erasable Programmable
Read-Only Memory)
