Backplane Bus Communication Velocity & I/O Density Scaling
The IC693ALG222 updates digitized 12-bit voltage representations directly to the CPU logic memory table via the backplane bus. Designed to optimize backplane bus communication velocity and I/O density scaling, it converts unipolar (0 to 10 VDC) or bipolar (-10 to +10 VDC) analog inputs across up to 16 channels in a single rack slot. Firmware flash compatibility supports automated rack scanning with channel update times down to 3 ms in differential mode and 6 ms in single-ended mode. The field-to-logic interface maintains 1500 V RMS isolation to prevent noise propagation across the backplane.
Frequently Asked Questions
Q: What are the backplane current draw requirements for the IC693ALG222?
A: The module draws 112 mA from the +5 VDC backplane bus for internal logic and 41 mA from the isolated +24 VDC backplane supply to power onboard field-side converters.
Q: What system CPU limits exist for installing multiple IC693ALG222 modules?
A: A maximum of 4 modules can be installed with CPUs 311, 313, or 323; 8 modules with CPU331 or CPU351; 12 modules with CPUs 340/341; and up to 51 modules with CPUs 350 through 364.
Q: How do update rates and filter frequencies differ between wiring configurations?
A: Single-ended mode provides an update rate of 6 ms per channel with a 41 Hz filter response, whereas differential mode yields a 3 ms per channel update rate with an 82 Hz filter response.
Field Installation Guidelines
- Remove primary system power from the Series 90-30 baseplate before inserting or removing the module.
- Align the module chassis with any open I/O slot in a 5-slot or 10-slot baseplate and push until the rear edge connector firmly seats into the backplane bus.
- Tighten the top panel retention screw to secure frame grounding and mechanically lock the module in place.
- Wire field input sources to the removable terminal block according to either the 16-channel single-ended or 8-channel differential wiring diagrams.
- Route low-voltage analog signal cables in grounded metal conduits separate from AC power circuits, connecting overall cable shields at a single chassis ground point.
