Product Description:

The 502-04153-00 is a power and communication module produced by Kollmorgen for the PIC900 Drives series. Within a PIC900 motion system, the unit distributes low-voltage logic power and maintains serial links that let the drive exchange status and commands with host controllers. By combining regulated DC outputs, real-time clock support, and dual RS232 ports, the module supplies the support functions needed to keep the axis controller active during machine cycles and standby periods. Its role is centered on stable housekeeping power and dependable data exchange rather than direct motor power conversion.

The module delivers a total of 40 W of DC power that is divided among three regulated rails. The logic plane uses a +5 V output rated at 5.0 A, while analog circuitry is served by a +15 V output of 2.0 A and a complementary -15 V output of 0.5 A. A maintenance-free clock is powered by an internal lithium cell with a nominal 1.2 Ah battery capacity, which helps preserve timekeeping during extended power-off periods. The cell operates at 3 V, and the on-board oscillator maintains daily accuracy suitable for time-sensitive control records and scheduled machine events. This arrangement supports logic, analog, and clock functions from one module without requiring separate auxiliary boards.

The control logic communicates through two independent RS232 links. The PicPro service port reaches a maximum rate of 57,600 baud, while the user port supports 19.2 Kbaud and uses RTS/CTS handshaking for flow control. Both ports follow EIA-232 voltage levels, allowing direct connection to compatible PLCs or PCs without external converters. Cabinet layout is simplified by a slim enclosure that is 2.4 in wide, 8.4 in deep, and 12 in high. That narrow format helps the module fit standard drive racks while leaving room for adjacent components and normal airflow paths inside the enclosure.
