Physical Construction and Component Layout

This TSXAEG4111 analog input module measures 4.3 inches in height. Its width reaches 3.1 inches with a depth of 2.7 inches. The total weight comes to approximately 0.52 pounds. Manufacturers placed 112 discrete components on this compact PCB. These components include amplifiers, multiplexers, an ADC, and precision resistors. The board uses a four-layer design for noise reduction.

Input Configurations and Signal Ranges

TSXAEG4111 provides four differential analog input channels for field devices. Each channel handles voltage signals of 0-10V or ±10V. Alternatively, each channel accepts current signals of 4-20 mA or 0-20 mA. Software configuration selects the appropriate range per channel. Voltage mode offers 1 MΩ input impedance for minimal loading. Current mode uses 250Ω impedance for standard loop compatibility. Consequently, this module connects to most sensors and transmitters directly.

Resolution and Conversion Performance

The analog input module delivers 12-bit resolution plus a sign bit. This gives you 13 effective bits of measurement precision. Resolution reaches 2.44 mV for the 0-10V voltage range. For current signals, resolution reaches 4.88 µA per step. Conversion time measures 5 milliseconds per channel. Total scan time for all four channels reaches 20 milliseconds. Accuracy stays within ±0.3% of the full scale range. Therefore, the TSXAEG4111 provides reliable data for monitoring applications.

Energy Storage and Application Use

TSXAEG4111 integrates four 100µF capacitors on the input power rail. Two additional 47µF capacitors filter noise near the ADC circuit. The module draws only 95 milliamps from the 24V DC backplane. Optical isolation separates each input channel from the internal bus. This isolation withstands 500V AC for safe field wiring. You will find this module in Modicon TSX Premium PLC racks. For example, it monitors temperature, pressure, or flow signals. The unit operates reliably from 0°C to 55°C ambient. Therefore, this input module delivers accurate analog acquisition for process control.
