Product Applications
Features:
- 4 MB user memory and 0.98 MB I/O memory
- Scalable I/O capacity
- Capacitor-based energy storage modules
- Low backplane power consumption
- Wide environmental tolerance
The controller provides 4 MB of user memory for data and logic, along with 0.98 MB of pre-allocated I/O memory. Nonvolatile memory is handled via a Secure Digital card; the unit ships with a 1 GB 1784-SD1 card, with an upgrade path to 2 GB via the 1784-SD2. The SD card stores diagnostic data written automatically during faults.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Backplane Power Balancing: Ensure the sum current draw of all modules across the 1.2V, 5.1V, and 24V backplane rails does not exceed the continuous current limits of the selected power supply (e.g., 1756-PA72 or 1756-PB75).
Inductive Suppression: Never connect field device wiring directly to backplane terminal connections without physical line filtering or external isolation. Use external suppression blocks (diodes for DC circuits, MOV/RC snubbers for AC circuits) on all interposing relays and solenoid coils to block destructive electrical noise.
