Multi-Variable Analog Interface
for Smart Transmitters


The MVA, Multi-Variable Analog interface for smart transmitters converts a single transmitter's digital PV or SV signals into four (4) 1-5 volt analog signals. Each module's output is factory characterized to an accuracy of 0.045%. In addition to analog outputs, a "smart status" relay output is provided that is derived directly from the transmitter's digital status.

The MVA provides a cost effective way to interface into analog instrumentation while utilizing all the advantages of Honeywell's DE digital communications.

The MVA is fully compatible with all single and multi-variable DE transmitters. It can be used in conjunction with any of the DE control system interfaces. In addition, handheld communicators may be used with NO disturbances to the analog outputs or status.

The MVA 's compact module design is suitable for DIN rail mounting and can be conveniently mounted in close proximity to the analog instrumentation. The MVA operates from a single +24VDC source and is internally short-circuit protected. All connectors are screw compression type and removable.


bullet Allows mixing of digital and analog instrumentation.
bullet Expands functionality while maintaining full digital integration.
bullet Access to all variables .
bullet Wiring savings associated with multivariable transmitters.
bullet Increase overall analog accuracy 80%.
