Siemens 6ES5460-7LA11 Analog Input Module

The 6ES5460-7LA11 converts analog field signals into digital values for SIMATIC S5 systems. This module accepts voltage or current inputs from sensors and transmitters. Its rectangular frame measures 232 millimeters in width. The module height reaches 210 millimeters exactly. Depth stays at 155 millimeters. You will find this unit weighs approximately 0.86 kilograms. Therefore, installation requires sliding the module into a standard S5 rack slot. One 20-pin front connector handles all field wiring connections.

Physical Layout and Connectors

The front connector accepts wires up to 16 AWG gauge. Each channel uses two terminals for signal and return paths. A green LED indicates power present on the module. Two guide rails secure the module firmly in the rack. You can remove the front connector without disconnecting the module from the backplane.

Internal Design and Energy Storage

The 6ES5460-7LA11 contains exactly 312 discrete components onboard. A 680 microfarad capacitor bank filters noise from the internal power supply. Eight independent signal conditioning circuits handle each input channel. Each circuit includes programmable gain amplifiers for range selection. A 12-bit analog-to-digital converter samples channels sequentially. The module also provides overvoltage protection on every input pin.

Operational Performance

This analog input module accepts voltage signals from 0 to 10 volts. It also reads current signals from 4 to 20 milliamperes. Moreover, the unit performs automatic range detection for each channel. You can configure each channel independently using PLC software. The module filters 50 Hz and 60 Hz noise with digital filtering. Eight green LEDs indicate active channels during normal operation. Consequently, you achieve accurate analog measurement for process control. Siemens designed this module for SIMATIC S5 automation platforms. Its shielded design rejects electromagnetic interference effectively.

In summary, the 6ES5460-7LA11 delivers precise analog input conversion. Use this module for temperature, pressure, or flow monitoring. It provides 12-bit resolution for reliable measurements. Order this analog input module for your Siemens S5 system.
