The ABB AE/S 4.1.1.3 Analogue Input (order code AE/S4.1.1.3) detects and processes four independent analogue signals on an MDRC rail. Typical inputs include 0…1/5/10 V, 0/4…20 mA, 0…1000 Ω, PT100/PT1000, and floating contacts.

An integrated 24 V DC sensor supply (up to 300 mA) powers active transmitters. Mains auxiliary covers the common 115…230 V AC range (wider AC range per technical data).

Key Features

• 4 independent inputs: Voltage, current, resistance, PT100/PT1000 (2- and 3-wire), contacts.
• Integrated 24 V DC supply: Up to 300 mA for external sensors across the voltage range.
• Mains auxiliary: 115…230 V AC, 50/60 Hz (see technical data for full range).
• MDRC 4 MW: Compact DIN-rail mount for distribution boards.
• ETS + i-bus Tool: Parameterization and advanced diagnosis.
• Surface-mount sister: Two channels, bus-powered IP54 — AE/A2.1.

Applications

• HVAC sensor hubs: Collect multiple 0–10 V / 4–20 mA transmitters in one MDRC.
• Temperature arrays: PT100/PT1000 with 2- or 3-wire wiring in plant rooms.
• Active sensors: Use the integrated 24 V DC supply instead of a separate PSU.
• Field / IP54: Prefer AE/A2.1 near the sensor; drive actuators with AA/S4.1.2.

Installation Notes

Mount on a 35 mm DIN rail (4 MW). Connect KNX, mains auxiliary, sensor supply outputs, and analogue inputs per the connection diagram. Import the official .knxprod from Downloads; use ABB i-bus® Tool for diagnostics where required.
