Product Profile

140DAO85300 is a high-density AC discrete output module from Schneider Electric's Modicon Quantum automation platform. It provides 32 independent output channels organized into 4 isolated groups of 8 channels, designed for controlling AC loads in demanding industrial environments.

The module operates with a versatile voltage range of 20 to 253 V AC at 47-63 Hz, making it suitable for global power systems. Each output channel supports up to 1 A RMS continuous current, with group-level protection via internal 4 A fuses and RC snubber filters.

The 140DAO85300 features a rapid response time of ≤ 0.5 ms for both on-to-off and off-to-on transitions, ensuring real-time control performance. It includes comprehensive LED status indicators for bus communication, fault detection, and per-channel output status.

System Role

The 140DAO85300 functions as the primary AC output interface between the Modicon Quantum PLC and field devices requiring AC control. It converts digital control signals from the Quantum CPU into high-voltage AC outputs for driving solenoid valves, motor starters, contactors, pilot lights, and other AC-powered actuators.

The module's 4 isolated groups of 8 channels provide electrical isolation between output banks, allowing different AC phases or voltages to be applied to each group while maintaining system safety. This group isolation is critical for applications where multiple control zones or voltages are required within the same I/O rack.

With a response time of ≤ 0.5 ms, the module supports high-speed control applications, making it suitable for processes requiring rapid output switching. The integrated RC snubber filter and varistor protection reduce electromagnetic interference when switching inductive loads.

Compatibility notes:
  • The field wiring terminal strip (140 XTS 002 00) is not included with the module and must be ordered separately.
  • Each group must be powered from a common single-phase AC power source to ensure proper operation.
  • For inductive loads, an external varistor (Harris V390ZA05 or equivalent) must be used in parallel with the external switch to protect the module outputs.
  • The module uses True High (source) logic, meaning outputs are energized when the corresponding bit is set to 1.
