Product Description:
The 502-03548-00R3 is a discrete input module produced by Kollmorgen for the PIC900 Drives series. It accepts field signals and transfers their state to the PIC900 controller backplane, allowing the drive system to monitor machine sensors such as limit switches or proximity detectors. By isolating and conditioning incoming 24 VDC control lines, the board helps protect the drive electronics and maintain reliable logic processing in industrial automation cells. Because the inputs are delivered to the controller as conditioned logic states, the system can respond to interlocks, presence sensors, and other binary devices without exposing low-voltage logic circuits directly to field wiring.
The module dissipates at most 3.6 W as heat during normal operation, which is useful when enclosure airflow is limited. It offers 16 opto-isolated input channels, so one board can monitor multiple field devices at the same time. A galvanic barrier rated at 4000 V peak helps shield the logic plane from high common-mode transients. Each channel tolerates up to 7.5 mA at 30 VDC and can withstand continuous exposure to 30 VDC without damage. This channel count can reduce the number of separate input boards required in a compact rack. State changes propagate quickly, off-state leakage is limited to 0.75 mA, and input polarity is independent so sourcing or sinking sensors can be connected without rewiring.
The module reaches its active state at the system's 24 VDC nominal input level, and signal recognition occurs within the 1 ms on-delay limit. Deactivation follows when input voltage falls below the 5 V turn-off threshold, and the circuitry switches reliably once current rises above the 2.8 mA minimum at 14 VDC. The short response timing is useful where the drive must react quickly to limit or status changes from external devices. Continuous service is permitted from 7 to 55 °C, which supports installation near other control hardware inside industrial cabinets. Storage or transit can occur from -40 to 85 °C without performance loss.
