Schneider 140DAO84000C Discrete Output Module for Modicon Quantum

The Schneider 140DAO84000C drives AC actuators directly from Modicon Quantum PLCs. You can install this module into any standard Quantum rack slot. It provides eight triac output channels for 115 V AC or 230 V AC loads. This unit suits solenoid valves, motor starters, and heating elements.

Technical Specifications and Hardware Layout

The Schneider 140DAO84000C measures 138 mm in height. Its width reaches 54 mm, and the depth equals 145 mm. The Schneider 140DAO84000C weighs approximately 0.38 kilograms. A single internal PCB holds all output switching and isolation circuits. The module provides eight triac outputs for AC loads. It stores no energy in capacitors or internal batteries. One 48-pin front connector handles all field wiring connections. Eight red LEDs display the real-time status of each channel.

Output Specifications and Electrical Ratings

The Schneider 140DAO84000C switches loads at 115 V AC or 230 V AC nominal. Each channel handles a continuous current of 2 A maximum. The total current per module reaches 8 A. Each output includes an internal snubber circuit for inductive loads. Consequently, this module reduces contact wear on external relays and contactors. The triac outputs switch at frequencies up to 15 Hz for cycling applications. Optical isolation separates the field side from the backplane logic. The module requires no external fuses for short-circuit protection.

Installation and Practical Application Tips

You must insert the Schneider 140DAO84000C firmly into a standard Quantum rack slot. Transitioning to wiring, use 0.5 mm² to 1.5 mm² stranded copper wire. The screw-type terminals require a 3 mm flathead screwdriver for tightening. For highly inductive AC loads, add external RC snubbers for extra protection. The operating temperature range extends from 0°C to 60°C reliably. This module consumes only 80 mA from the backplane bus.
