Product Description
The AAT141-S50 is a high-precision, 16-channel analog input module for Yokogawa CENTUM VP and ProSafe-RS systems. Designed for low-level signal acquisition, it supports Thermocouples (TC) and millivolt (mV) inputs, with full channel-to-channel isolation to prevent ground loops and common-mode interference.
Each channel is independently configurable, allowing flexible assignment of sensor type or input range. The module features burnout detection to alert the control system immediately in the event of an open-circuit sensor. Its robust isolation (1500 V AC) and high input resistance make it a reliable choice for long-term, high-fidelity temperature monitoring in demanding industrial applications.

Industrial Application
The AAT141-S50 is widely used in:
-
Power generation (furnace and boiler temperature monitoring)
-
Metal smelting
-
Glass manufacturing
-
Chemical reactors requiring isolated, high-density temperature monitoring
Its 16 isolated channels ensure that multiple thermocouple or millivolt sensors do not interfere with each other, maintaining signal integrity for critical process control.
Frequently Asked Questions
Can I mix different Thermocouple types on a single module?
-
Yes. Each channel can be individually configured via software for a different TC type or millivolt range, enabling flexible and diverse sensor arrays on one module.
What happens if a sensor wire breaks?
-
The module’s programmable burnout detection can be set to drive the signal Full Scale Up or Full Scale Down upon detecting an open circuit. This allows the system logic to immediately trigger alarms or initiate a safe shutdown.
