Product Description:

The M.1017.3138 is an analog interface card manufactured by Danaher for the Block IO Analog Modules series. It serves as the field-side component that excites a resolver, interprets its sine-cosine signals, and forwards the resulting position values to upstream control hardware. By housing excitation drivers, signal-conditioning circuits, and termination blocks on one compact board, the device reduces panel wiring and supports coordinated axis operation in automated test stands, conveyors, and multi-station assembly systems.

The module is powered from a control rail of 24 VDC and draws approximately 200 mA during steady operation. At power-up, it momentarily requires 2.5 A for 250 µs, so this inrush should be considered when sizing supply fuses and bulk capacitors. Once energized, its internal amplifier can deliver up to 100 mA of excitation current while maintaining a fixed carrier frequency of 4 kHz, providing consistent resolver magnetization across the supported speed range. The board supports six resolver channels, and each input may be located as far as 100 ft from the module when the cable follows the appropriate shielding and wire-gauge requirements.

The signal amplitude at the excitation terminals is maintained at 15 V peak-to-peak, providing sufficient margin for expected line losses and supporting reliable decoding at rotor speeds up to 15,000 electrical rpm. The conversion engine resolves each electrical revolution into 4,000 feedback units per electrical revolution, while the built-in potentiometer path provides 1,000 counts for coarse angle monitoring. Static accuracy remains within ±12 arcminutes at a constant temperature. The drift coefficient is ±5.4 arcminutes per 10 °F, allowing system error to be assessed as plant temperatures change. Cable length between the module and its removable terminal block is limited to 6 ft, providing convenient maintenance access without degrading signal integrity.
