Resolver Interface Provides Six Channels

The 7I49, a daughtercard for the company’s Anything I/O series of FPGA-based interface cards, is a six-channel resolver interface with six additional ±10V analog outputs. The card is useable with 1:1 and 1:2 transformation ratio resolvers and delivers approximately 14 bits of resolution and 12 bits of absolute accuracy. The FPGA interface module allows velocity and absolute position readout by the host. Other features include selectable excitation frequencies from 2.5 kHz up to 10 kHz. Price for the 7I49 is $123 each/100. MESA ELECTRONICS, Richmond, CA. (510) 223-9272.
