Product Description

The 140DAI55300 is a 16-channel discrete AC input module designed for the Schneider Electric Modicon Quantum PLC platform. It is engineered to monitor 115 VAC field signals from devices such as limit switches, pushbuttons, motor starters, and relay contacts.

This module converts high-voltage AC input signals into logic-level data for processing by the Quantum CPU, enabling reliable real-time monitoring of machine and process states. Designed for harsh industrial environments, the 140DAI55300 incorporates robust optical isolation to protect the PLC backplane from electrical noise, voltage surges, and transient disturbances.

Its 16 inputs are grouped into a single common configuration, making it suitable for motor control centers (MCCs), alarm systems, and plant-wide discrete monitoring applications where 115 VAC is the standard control voltage.

Technical FAQ

Does the 140DAI55300 require a specific terminal block?
Yes. It is typically used with a compatible Quantum terminal block such as the 140XTS00200 for secure field wiring connections.

What is the input response time?
The module includes built-in hardware filtering (typically 25–30 ms) to prevent false triggering caused by contact bounce or electrical noise.
