Technical Specifications Order Number: 1SAP250300R0001 Operating Supply Voltage: 24 VDC ±10% Number of Input Channels: 16 configurable analog input channels Supported Signal Types: 0‑20 mA, 4‑20 mA, ‑10‑+10 V, 0‑10 V, Pt100, Pt1000, Ni1000 A/D Resolution: 12‑bit including sign Isolation: Module‑wide galvanic isolation Operating Temperature: ‑20 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mounting Form: Standard 35 mm DIN‑rail mounting Protection Class: IP20 Certifications: CE, DNV, CSA
Functional Features 16 multi‑purpose channels support current, voltage and multiple RTD temperature sensors. Module‑wide galvanic isolation eliminates ground‑loop interference between field side and PLC system. Built‑in sensor loop open‑circuit and short‑circuit fault diagnosis function. LED indicators for channel signal status, power supply status and module fault alarm. Supports software‑driven channel parameter configuration, no hardware jumper adjustment required. Compact DIN‑rail installation structure saves cabinet internal space. Detachable terminal blocks simplify field wiring and module replacement operation. Perfect compatibility with AC500 series PLC and S500 bus coupler units.
Application Scenarios AC500 PLC automation project multi‑point analog signal acquisition. Factory production machinery process parameter monitoring cabinet. Water‑treatment, building automation analog measurement and control system. S500 distributed remote I/O station signal collection application.
Installation Requirements Mount AI523 module onto standard 35 mm DIN‑rail inside control cabinet. Connect module back‑side I/O bus connector to matched S500 bus coupler. Complete cabinet protective earth connection according to system grounding specification. Field sensor wiring adopts shielded twisted‑pair cables. Separate power‑cable and signal‑cable routing. Confirm channel signal type matches software configuration parameter before power‑on. Ambient operating environment stays within defined temperature and humidity range without condensed moisture. Tighten spring‑cage terminal blocks according to wiring specification to avoid poor contact.
