Product Description:
The 502-03782-02R3 module is produced by Kollmorgen as part of the PIC900 Drives series. It is an I/O expansion card that adds high-speed counting and encoder feedback to a PIC900 motion system, allowing controllers in automated assembly, packaging, or material-handling lines to capture rapid edge transitions and maintain accurate position data. By combining differential inputs with on-board counters, the card transfers electrical signals from encoders or contact switches to the digital domain of the drive and supports deterministic motion sequences.
The module occupies a compact slot footprint measuring 305 mm in height, 41 mm in width, and 213 mm in depth. Its front termination block accepts up to 4 encoder channels that are decoded by an internal 24-bit up/down counter, giving the controller enough range for long travel axes without rollover events. Each fast input presents a 2.7 kΩ impedance to limit loading on source devices while respecting a maximum input voltage of 7 V DC. Reliable logic recognition starts at a guaranteed-on level of 2.5 V DC at 2.5 mA, and the circuitry draws no more than 22 mA per point at that limit. For installations that interface to industrial sensors, the terminals can tolerate surge levels up to 30 V DC.
Dynamic performance is governed by a nominal field supply of 24 V DC, enabling fast inputs to toggle within a maximum on/off interval of 50 µs. Under these conditions the module reliably counts pulse streams up to 500 kHz in single-ended mode or 250 kHz when quadrature decoding is selected, provided each edge maintains a minimum 0.6 µs width. Internal logic and LED drivers dissipate only 7.4 W, allowing the card to stay within temperature limits even when all channels operate near the ceiling frequency, which helps the drive execute tight velocity loops and position latching without missing transitions on fine-pitch encoders.
