Schneider 140DAO84210C Discrete Output Module

The 140DAO84210C provides 16 discrete output channels for Schneider Quantum PLC systems. This module switches DC loads directly from your control logic. Its rectangular frame measures 166 millimeters in width. The module height reaches 140 millimeters exactly. Depth stays at 115 millimeters. You will find this unit weighs approximately 0.58 kilograms. Therefore, installation requires sliding the unit into a standard Quantum rack slot. One 20-pin removable terminal block handles all field wiring connections.

Physical Layout and Connectors

The 20-pin terminal block accepts wires up to 14 AWG gauge. Each channel uses one pin for the output and a common return. A green LED illuminates when the corresponding output activates. Four mounting screws secure the module firmly in the rack. You can remove the terminal block without disconnecting field wires.

Internal Design and Energy Storage

The 140DAO84210C contains exactly 198 discrete components onboard. A 560 microfarad capacitor bank filters the internal logic supply voltage. Sixteen power MOSFETs perform the actual output switching duties. Each MOSFET includes built-in overcurrent shutoff protection. Individual optocouplers isolate the logic side from field power. The module also includes LED drivers for the 16 status indicators.

Operational Performance

This discrete output module sources 24V DC to field devices like relays. It handles up to 0.5 amperes per channel continuously. Moreover, the module provides short circuit protection on every output. You can connect incandescent lamps, solenoids, or indicator LEDs directly. The unit reports overload faults back to the PLC processor. Sixteen status LEDs show real-time output states at a glance. Consequently, you achieve reliable control of factory floor equipment. Schneider designed this module for Quantum automation platforms. Its conformal coating resists humidity and light contamination.

In summary, the 140DAO84210C delivers robust discrete output control. Use this module for machine automation or conveyor systems. It ensures dependable switching across all 16 channels. Order this output module for your Schneider Quantum PLC rack.
