Description
The Schneider Electric TSXDEY16A2 is a 16-channel discrete input module designed for integration within the Modicon Premium automation system. This module is specifically engineered to interface with 24 V AC field devices, including limit switches, auxiliary contacts, and safety interlocks. By utilizing integrated filtering and optical isolation, the TSXDEY16A2 ensures robust signal integrity, effectively mitigating the effects of contact bounce and electrical noise commonly encountered in heavy industrial environments such as power generation and chemical processing.
Features
- 16 independent input channels configured in a single isolated group.
- Designed for 24 V AC nominal input voltage applications.
- Integrated hardware filtering to suppress high-frequency noise and transients.
- 1500 V AC dielectric isolation barrier between field inputs and the internal backplane.
- Compact module design utilizing a standard HE10 connector interface.
- High noise immunity for reliable state monitoring in demanding electrical environments.
Applications
This module is suitable for use in various industrial automation sectors where AC status sensing is required. Typical applications include monitoring field-mounted switches in mining crushers, utility process control, and large-scale manufacturing equipment where AC signaling is the standard for field device communication.

Installation Guidelines
- Ensure the rack power is disconnected before installing or removing the module to prevent damage to the backplane connectors.
- Verify that the field wiring is correctly routed away from high-voltage power cables to minimize electromagnetic interference.
- Ensure the module is fully seated in the rack slot and secured using the integrated locking mechanism.
- Use shielded cables for field inputs where long cable runs are required to maintain signal integrity.
- Observe proper environmental conditions, ensuring the cabinet is well-ventilated to maintain ambient temperatures within the 0 to 60 deg C range.
FAQ
What type of field devices can be connected to the TSXDEY16A2?
This module is designed for 24 V AC devices such as mechanical switches, pushbuttons, and auxiliary contacts of contactors or relays.
Does this module require external power for the inputs?
The inputs are powered by the 24 V AC field supply. The module itself draws its internal logic power (50 mA) from the Modicon Premium rack backplane.
What is the purpose of the 15 ms filtering delay?
The 15 ms delay is a hardware-based debounce feature that prevents the module from registering false signals caused by mechanical contact bounce or brief electrical transients.
