THE INTERBUS NETWORK RESOLVER

The InterBus Network Resolver is a resolver-based encoder, in which the analog signal produced by a brushless resolver is transformed to a digital format by a built-in ratiometric tracking converter. This new concept and the advanced technology of the InterBus Network Resolver, with electronic circuitry provides higher accuracy, increased reliability, higher operating speeds, more flexible counts per turn, and a smaller size than optical encoders.

No Optics, MIL-Grade Resolver
There is no optically encoded disc or similar component used in the InterBus Network Resolver. A miniature MIL-Grade resolver produces an analog position signal and high-grade electronics molded in epoxy transforms this signal to digital format. The resolver is a passive transducer, well known for its ruggedness and performance in hostile industrial environments. The Network Resolver combines the ruggedness of a resolver with the reliability of solid-state electronics and is designed to operate reliably under severe environmental conditions, such as: mechanical shock, vibration, temperature and humidity changes, oil mist, coolants, and solvents. No broken discs! No disc misalignments! No LED aging!

High Resolution in a Small, Compact Housing
The single-turn InterBus Network Resolver provides up to 12-bit Binary, Gray Code, or BCD in either a size 25--2.5" (63.5 mm) or a size 40--4.0" (101.6 mm) diameter housing.

Single-Turn Operation
The InterBus Network Resolver is an absolute encoder. That is, it keeps track of the exact shaft position even during a power outage or switching off the machine. At power-up, the Network Resolver will pick up the exact shaft position even if the machine moved during the power outage. In a single-turn operation, the machine cycle is completed during one complete revolution of the transducer shaft.

Field-Selectable CW or CCW Operation
The InterBus Network Resolver is factory-wired for ascending counts with CCW shaft rotation. However, the direction of operation can be easily selected in the field by opening up the case and simply reversing the resolver-input plug. No wires need to be unsoldered or soldered.

Ratiometric Resolver-to-Digital Converter
The AVG Automation ratiometric-converter is practically immune to electrical noise, voltage, frequency and temperature variations, and can track speeds up to 5000 RPM.

INTERBUS CONNECTION 

The InterBus Network Resolver model is enclosed in a size 25--2.5" (63.5 mm) or size 40--4.0" (101.6 mm) diameter, NEMA 13 housing and designed for medium-duty (size 25) or heavy-duty (size 40) applications. It is available as a flange mount (size 25), a servo mount model (size 25), or face mount (size 40) with an InterBus connector at the end.
