Introduction
The Schneider Electric 140DAO84220 is a high-density AC discrete output module. It belongs to the Modicon Quantum automation platform. This module controls AC loads directly from the PLC backplane. Accordingly, the 140DAO84220 delivers reliable switching for industrial valves, contactors, and indicators.
Technical Specifications
Output Characteristics
This discrete output module provides 16 individual AC outputs. These outputs are arranged in 4 groups of 4 channels each. Specifically, the discrete output voltage range is 20…56 V AC . The supply frequency operates from 47 to 63 Hz . Maximum voltage drop across each output is only 1.5 V . Furthermore, the 140DAO84220 requires just 1 output word for addressing.
Load Current Ratings
Maximum load current reaches 16 A rms per module . Each group handles 4 A rms continuously. Consequently, each output channel handles 4 A rms at 20-56V AC. Surge current withstands 45 A for 1 cycle per group . It also withstands 25 A for 2 cycles per group . Another rating shows 30 A for 3 cycles per group .
Absolute Maximum Outputs
The 140DAO84220 handles 100 Vrms for 1 cycle AC . It also handles 63 Vrms for 10 seconds AC . A third rating shows 111 Vrms for 1.3 seconds AC . However, these are fault conditions only, not normal operation.
Response Time and Protection
Response time from state 0 to state 1 is <= 0.5 ms . Similarly, response time from state 1 to state 0 is also <= 0.5 ms . Moreover, the module has a DV/dt rating of 400 V/ms . Protection includes an internal RC filter for noise suppression. In addition, internal output protection uses a 5 A fuse per channel.
Diagnostics and Local Signaling
Fault indication includes blown fuse detection. It also includes loss of field power monitoring. Local signaling provides clear status at a glance. For example, one green LED shows bus communication is present (Active). One red LED indicates an external fault detected (F). Sixteen green LEDs show the status of each input channel.
Electrical and Environmental Data
Bus current requirement for the 140DAO84220 is 350 mA . Module format is standard for the Quantum rack. Power dissipation equals 1.85 + (1.1 V x total module load current) . As a result, net weight is only 0.45 kg (0.99 lb) .
Temperature and Humidity
Ambient air temperature for operation is 32…140 °F (0…60 °C) . Storage temperature ranges from -40…185 °F (-40…85 °C) . Relative humidity reaches 95 % without condensation. Therefore, operating altitude goes up to 5000 m (16404 ft) .
Certifications and Standards
The 140DAO84220 complies with UL 508 and CSA C22.2 No 142 standards. Product certifications include FM Class 1 Division 2 and cUL . The module features CE marking for European markets.
Electromagnetic Compatibility
Electrostatic discharge immunity reaches 4 kV contact discharge per IEC 801-2. Air discharge immunity reaches 8 kV per IEC 801-2. Finally, susceptibility to electromagnetic fields reaches 10 V/m from 80 to 1000 MHz per IEC 801-3.
Installation Guidelines
Install the 140DAO84220 in any standard Quantum I/O slot. Always power down the rack before inserting or removing the module. Connect field power to each group of four outputs. Use proper fusing on each output for external protection. After power-up, verify the Active LED is green. Similarly, monitor the red F LED for field power or fuse faults.

Frequently Asked Questions (FAQ)
1. What voltage range does the 140DAO84220 support?
This module supports AC voltages from 20V to 56V AC at 47-63 Hz. Therefore, do not apply DC voltage to these outputs.
2. How many outputs does the 140DAO84220 provide?
The module provides 16 discrete AC outputs arranged in four groups. Specifically, each group contains four isolated channels.
3. What is the response time of the 140DAO84220 ?
Response time is 0.5 milliseconds for both turning on and turning off. Consequently, this ensures fast control of connected loads.
4. How do I know if an output fuse has blown?
The red F LED will light up when a fuse fails. Additionally, the module detects loss of field power through the same indicator.
5. Can the 140DAO84220 handle surge currents from inductive loads?
Yes, each group handles 45A for one cycle and 25A for two cycles. As a result, this accommodates typical inrush currents from contactors and solenoids.
