Schneider Electric TSXAEY1600 Modicon Premium Analog Input Module

The Schneider Electric TSXAEY1600 is a 16-channel high-level analog input module engineered for the Modicon Premium Automation platform. Designed to process continuous industrial process variables, this module acquisition unit converts standard voltage and current signals into digital values with 12-bit resolution. It interfaces directly with field sensors such as pressure transmitters, flowmeters, and temperature signal conditioners across automated manufacturing and process monitoring installations.

Signal Configuration and High-Density Connectivity

The module provides 16 analog input channels sharing a single common point, accommodating flexible field instrument configurations. Channel input ranges can be configured for standard voltage spans (±10 V, 0...10 V, 0...5 V, 1...5 V) and current loops (0...20 mA, 4...20 mA). Field connections are routed through two front-mounted SUB-D 25 connectors, allowing high-density wiring and quick disconnect during system servicing.

Built-in protection circuitry safeguards inputs against sustained overvoltage up to ±30 V and overcurrent up to ±30 mA in state 1. Internal galvanic isolation provides 1000 Vrms dielectric withstand between the field channels and the Premium backplane bus, as well as between field wiring and chassis ground.

Sampling Performance and Environmental Design

The TSXAEY1600 supports dual conversion execution modes to match system dynamics. Under standard scan operation, the nominal read cycle time is 51 ms for all channels. For time-critical process loops, a fast read cycle mode reduces execution time to 3 ms plus 3 ms per active channel. Measuring accuracy is maintained within 0.1% of full scale for voltage ranges and 0.16% for current inputs at 25 °C.

Housed in a standard Premium module form factor with an IP20 rating, the module operates under ambient panel temperatures ranging from 0 to 60 °C and relative humidity up to 95% non-condensing.

Frequently Asked Questions

Q: How are field instruments wired to the TSXAEY1600 module?

A: Field instrument signals connect through two 25-pin SUB-D connectors on the module front panel. All 16 high-level channels share a common point reference without channel-to-channel isolation.

Q: How does the fast read cycle mode affect input update speeds on the TSXAEY1600?

A: While the default nominal update scan takes 51 ms for the full module, fast read mode calculates total sampling time based on active channels using the formula: 3 ms + (3 ms x number of channels used).
