Schneider Electric 140ACO02000 Programmable Logic Controller Module

Schneider Electric 140ACO02000 is a four‑channel analog output module for the Modicon Quantum PLC platform, delivering 4–20 mA control signals with 12‑bit bipolar resolution across four isolated outputs. The module operates with a loop supply of 12–30 V DC and requires a bus current of 480 mA, with external power also in the 12–30 V range and a maximum power dissipation of 5.3 W. Each channel provides 4–20 mA output into a range represented as 0–4096 counts (12‑bit bipolar), with isolation between channels rated at 500 V AC (47–63 Hz) or 750 V DC. Update time is 3 ms and setting time is 900 μs to within ±0.1% of the final value, while absolute accuracy is ±0.20% of full scale at 25°C and linearity within ±1 LSB; the module uses four output words addressing. Local signaling includes one green LED for bus communication, one red LED for external fault, and four green LEDs plus four red LEDs indicating channel status. Physical dimensions are 50 mm high by 250 mm long by 100 mm wide, with a net weight around 0.3 kg. Note: Schneider Electric classifies this model as discontinued as of January 9, 2023, with end‑of‑service on December 31, 2030, and a recommended replacement is BMXAMO0410.
