Schneider Electric TSXAEY800 Modicon Premium Analog Input Module

The Schneider Electric TSXAEY800 is an 8-channel high-level analog input module designed for the Modicon Premium automation platform. It processes standard industrial voltage and current signals with a 12-bit analog-to-digital conversion resolution. Featuring a fast scanning capability and a single 25-pin SUB-D interface, the TSXAEY800 provides efficient signal acquisition for centralized monitoring and control applications.

Signal Processing and Multirange Capability

The module supports eight high-level analog input channels with a shared common point. It accepts standard voltage signals (±10 V, 0–10 V, 0–5 V, and 1–5 V) as well as standard current signals (0–20 mA and 4–20 mA). Under normal operating conditions, the module achieves a nominal read cycle time of 27 ms, with an accelerated scan mode capable of 3 ms plus an additional 3 ms per configured channel.

System Architecture and Bus Connection

Designed for standard Modicon Premium rack slots, the module draws 270 mA from the internal 5 VDC backplane supply. The front faceplate incorporates a 25-pin SUB-D connector for direct field signal termination. Galvanic isolation of 1000 Vrms is maintained between the input channels and the backplane bus, as well as between the input channels and system ground, preserving backplane integrity during field disturbances.

Input Protection and Environmental Ratings

Integrated protection circuitry protects the analog inputs against overvoltage conditions up to ±15 V in passive state and ±30 V across a 250 Ohm load in active state. The module complies with IEC 1131 standards and holds major marine and industrial certifications, operating reliably within ambient temperatures ranging from 0 to 60 deg C (32 to 140 deg F) in IP20 enclosures.

Frequently Asked Questions

Q: How are field wiring connections made on the TSXAEY800 module? A: Field signals connect to the module through a single 25-pin SUB-D connector located on the front panel.

Q: Is channel-to-channel isolation supported on this module? A: No, the 8 channels share a common point and do not feature channel-to-channel isolation, though 1000 Vrms isolation is provided between the channels and the backplane bus or ground.
