AI-519 is an AI artificial intelligence industrial controller developed by Delta, which has various functions and can be used for accurate control of temperature, pressure, flow, level, humidity, etc.
This manual describes the features and operation of the Al‑519 artificial‑intelligence industrial controller. It covers the selectable input types (thermocouples, RTDs, linear voltage/current), the modular hardware design with up to five slots, and the various output options such as relay, TRIAC, SSR and thyristor modules.
Detailed sections include technical specifications, ordering code definitions, rear terminal layout and wiring diagrams, front‑panel operation, parameter settings, module installation and replacement procedures, and warranty information. The document also explains advanced functions like auto‑tuning, soft‑start, and communication settings.

The controller accepts thermocouples (K, S, R, E, J, N), RTDs (Cu50, Pt100), linear voltage signals (0‑5 V, 1‑5 V, 0‑1 V, 0‑100 mV, 0‑20 mV) and linear current signals (0‑10 mA, 0‑20 mA, 4‑20 mA).
The instrument provides a measurement accuracy of 0.3 %FS plus 0.1 °C.
The controller consumes less than 6 W of power.
Available outputs include a relay (NO+NC) rated 250 VAC/2 A or 30 VDC/1 A, a TRIAC no‑contact output 100‑240 VAC/0.2 A, an SSR voltage output 12 VDC/30 mA, and a thyristor zero‑crossing trigger for 5‑500 A loads.
