Backplane Bus Interfacing and Deterministic Networks

The IC693PTM101 processes raw transformer waveforms through a 14-bit analog stage and transmits RMS calculated values over the backplane bus. Utilizing high backplane bus communication velocity, the processing module updates CPU register memory (%I, %Q, %AI, and %AQ) every 16.67 ms (at 60 Hz) or 20 ms (at 50 Hz). Galvanic isolation of 1500 VAC between field transformer connections and the 5 VDC backplane bus maintains signal integrity and preserves firmware flash compatibility across local, expansion, and remote baseplate configurations.

Frequently Asked Questions

Q: What memory mapping registers are allocated in the Series 90-30 CPU for the IC693PTM101?

A: The module reserves 16 discrete input bits (%I), 16 discrete output bits (%Q), 25 analog input words (%AI), and 2 analog output words (%AQ) in the controller memory map.

Q: What operating modes can be configured on the IC693PTM101?

A: The module can be programmed via software to run in Single mode, 3-Phase mode (Wye or Delta configurations), or Synchro Monitor mode for generator-to-grid synchronization monitoring.

Q: What backplane power current draw does the processing module require?

A: The IC693PTM101 draws a maximum of 400 mA at 5 VDC directly from the Series 90-30 backplane power supply, with total power dissipation capped at 4 W.

Field Installation Guidelines

  1. Isolate primary rack power and disconnect external CT/PT secondary circuits prior to mounting or servicing the hardware.
  2. Wear an ESD grounding wrist strap clamped to an unpainted enclosure chassis frame to prevent static discharge to the processing card.
  3. Install the processing module into any available Series 90-30 baseplate slot and seat the interface board near the transformer terminal block.
  4. Interconnect the processing module and interface board using the provided IC693CBL340 cable, tightening retaining screws at both ports.
  5. Connect input signals within 10 to 120 VAC and 0 to 7.5 A limits, ensuring transformer shields and enclosure metalwork are firmly earth-grounded.
