MeloAuto-Trusted PLC & DCS Parts Supplier
The Schneider 140AIO33000C Analog Output Module provides four high-precision output channels for Quantum systems. This module converts digital values into 4-20 mA or 0-10 VDC signals. You will find it in process control applications requiring flexible signal ranges. It delivers 16-bit resolution for exceptional analog output precision. Therefore, this unit suits demanding industrial automation tasks.
The Schneider 140AIO33000C Analog Output Module measures 140 mm in height and 40 mm in width. Its depth reaches 120 mm for standard Quantum rack mounting. The unit weighs approximately 0.45 kilograms. It contains one 16-bit DAC with four sample-hold circuits. Four isolation barriers separate field circuits from the backplane. Additionally, you get four status LEDs for channel monitoring.

Internal Architecture and Energy Storage
The Schneider 140AIO33000C Analog Output Module stores minimal energy in its output filters. Small electrolytic capacitors hold approximately 220 microfarads total capacitance. A single 16-bit DAC generates analog values sequentially for all four channels. Four sample-hold circuits store each channel’s voltage or current simultaneously. Four optical isolators protect the backplane from field wiring noise. The module includes a precision voltage reference at 5.000 VDC. Each output can drive voltage loads down to 2 k ohms minimum. A yellow LED lights up when the module receives valid data from the CPU.
Connection Interfaces and Wiring Details
You will find a 20-pin removable connector on the bottom face. This block accepts four output pairs plus shield connections. Connect the positive output wire to the channel + terminal. Connect the negative wire to the adjacent – terminal. The Schneider 140AIO33000C Analog Output Module requires an external 24 VDC loop supply for 4-20 mA mode. For voltage mode, no external supply is necessary. Use shielded twisted-pair cable for runs longer than 10 meters. Connect the shield drain wire to the ground terminal only. Four yellow LEDs light up when their respective channel receives a non-zero value. A green PWR LED indicates proper backplane power.
Configuration and Installation Steps
You slide this module into any I/O slot of the Quantum rack. First, align the module with the upper and lower card guides. Then, push it firmly until the backplane connector seats completely. Secure the front panel with the two retaining screws. Connect all field wiring before applying power to the system. The Schneider 140AIO33000C Analog Output Module requires software configuration for output range. Use the Concept or Unity Pro software to select 4-20 mA or 0-10 V per channel. Map each analog channel to a specific %QW memory address. The module automatically scales digital values to the selected output range. Test each output with a multimeter or loop calibrator before connecting field actuators.
