Product Overview
The Schneider TSXAEY1600 is a 16-channel high-level analog input module for the Modicon Premium automation platform. It is a multirange input module supporting both current and voltage signals, making it suitable for process instrumentation, transmitters, monitoring systems, and other industrial measurement applications. Each channel can accept 0-20 mA, 4-20 mA, ±10 V, 0-10 V, 0-5 V, or 1-5 V signals, with 12-bit analog-to-digital conversion. The module provides channel-to-bus and channel-to-ground isolation rated at 1000 Vrms. Schneider Electric lists a nominal read cycle of 51 ms and a faster cycle of 3 ms plus 3 ms per channel used. The product has reached end-of-commercialization status, with Schneider currently identifying BMXAMI0810 as a recommended replacement.

Schneider TSXAEY1600
Key Features and Benefits
- 16 analog measurement channels in a standard Premium-format module.
- Supports both current and voltage signals without requiring separate input modules.
- 12-bit conversion provides suitable resolution for general industrial process measurement.
- High isolation helps protect the control architecture from field-side electrical differences.
- Dual SUB-D connectors provide the module’s field-wiring interface.
- Suitable for transmitters, sensors, process measurement loops, and machine instrumentation.
- Useful for maintaining existing Modicon Premium installations where legacy hardware remains in service.
Personally, I would keep this model as a controlled legacy spare rather than replacing it based only on channel count. Signal range, isolation, connector wiring, and Premium-rack compatibility all need to match the existing installation.

Installation and Maintenance
Before replacement, verify the Premium rack configuration, module position, wiring arrangement, input ranges, and channel assignments. Pay particular attention to the two 25-pin SUB-D connections because incorrect field wiring can affect multiple channels.
During maintenance, inspect connectors, terminal interfaces, shielding, grounding, and sensor-loop wiring. Check for abnormal input values caused by transmitter faults, broken loops, or incorrect scaling before assuming the module itself has failed. Follow the site’s approved PLC isolation and change-control procedures before removal.
Schneider Electric has discontinued commercial sales of this reference in several markets and currently lists 31 December 2026 as the end-of-service date. The recommended replacement is BMXAMI0810, but migration should be engineering-checked because it provides eight rather than 16 inputs.
Product Warranty
Warranty coverage depends on supplier, stock condition, and purchase agreement. For discontinued Premium hardware, confirm whether the unit is new old stock, refurbished, tested used, or surplus, and request test results and warranty terms before procurement.
The Schneider TSXAEY1600 remains a practical spare for installed Modicon Premium systems where preserving the original 16-channel architecture is more important than immediate platform modernization.
