Reliance Automax. In stock ships today. Resolver input module. 57C411. 57C-411. 57C411-2E. I/O. The Resolver Input module is used to input the angular position of a resolver rotor to the DCS 5000 system. The module provides 12-bit resolution or one revolution and a 2-bit revolution counter. The resolver position may be sampled from 500 microseconds to 32.767 seconds. An external strobe input is provided to permit synchronization of the DCS 5000 system to an external event. The module can be programmed to interrupt on every sample. Typically, this module is used to input rotary shaft position for the purpose of determining shaft position or velocity. Printed circuit board assembly. Plugs into the backplane of the DCS system. 12-bit digital number. Resolver-to-digital converter. The module produces a 26 volt rms 2381 Hertz sine wave reference output signal which is capable of driving a 400 ohm load. Transformer isolated. The module also receives 11.8 volt rms sine and cosine signals from the resolver, as well as the 26 volt rms reference. 5 LEDs on the faceplate. I/O Monitor Funtion. External Strobe Input.
