5X00062G01 Emerson Ovation Analog Output Module

Description

The Ovation™ HART 8-Channel Analog Output Module is engineered to interface with eight HART compliant output devices using a 4-20mA control loop signal. It allows for the exchange of digital information with the Ovation control system alongside the standard 4-20mA signal. This is achieved through a low-level frequency, shift-keyed sine wave signal superimposed on the 4-20mA signal, ensuring no interference with the control signal.

Features

• Eight Multiplexed Analog Output Channels: Each channel operates within a 4-20mA range generated by the HART Analog Output module.
• Shared Power Supply: Channels share a common external +24 VDC auxiliary power supply and ground.
• High-Speed Microcontroller: Equipped with a 16 MHz micro-controller for A/D and D/A conversion and HART interface control.
• High-Resolution A/D Conversion: Features a 14-bit A/D converter shared among the eight output channels.
• Signal Superposition: An array of switches superimpose transmitted signals upon each 4-20 mA analog output to the output device.
• Direct Control System Integration: Links the Ovation control system directly to intelligent field devices.
• AMS Suite Compatibility: Uses the AMS Suite, Device Manager for information collection and maintenance.
• Configurable Communication Timeout: Software configurable I/O bus communication time-out period.
• Electrical Isolation: 1000 VDC/RMS electrical isolation between field and logic circuitry.
• EEPROM Storage: Electronic ID information stored on logic board EEPROM.
