Schneider 140DAO85300C Discrete Output Module

Product Overview

The 140DAO85300C drives solenoids, relays, and indicator lamps in Quantum systems. You will find this module in material handling and packaging machinery. It provides 32 discrete output channels in a single rack slot. Moreover, this module includes built-in surge suppression on every channel. Therefore, it extends the life of connected inductive loads.

Mounting	Quantum rack slot

The 140DAO85300C stores no significant energy on its PCB. Therefore, you can handle this module immediately after power removal. Use the removable terminal blocks for all field device wiring. Meanwhile, each output bank requires a separate external 24V supply.

Installation and Compatibility

You can mount this module in any Quantum rack slot. Insert the 140DAO85300C into the chosen slot until the backplane locks. Then connect the field supply wires to each bank’s common terminal. Always install a fast-blow fuse on each output bank for safety.

This module works with all Quantum processors and remote I/O adapters. It also supports hot-swap replacement without system shutdown. The 140DAO85300C replaces older 140DAO85300 models with faster switching speed.

Environmental and Safety Data

The 140DAO85300C operates from 0°C to +60°C. It withstands 2g vibration per IEC 60068-2-6 testing. The circuit board has a full conformal coating. Consequently, you can use this module in humid or dusty environments. Do not exceed 0.5A per output channel under any condition.
