Application and Installation

The Siemens 6ES5460-4UA11 analog input module slots into any S5 rack alongside the CPU. It requires an external 24 V DC supply for field loop power. This module accepts signals from pressure, temperature, flow, and level transmitters. Consequently, you can monitor eight process variables with one module.

Signal Integrity and Reliability

This module filters electrical noise from every analog input channel. Its four-layer PCB design minimizes crosstalk between adjacent signals. The Siemens 6ES5460-4UA11 includes self-calibration for each input channel. Therefore, you maintain measurement accuracy without manual adjustments.

Always power down the rack before inserting or removing this module. Wire the field devices using shielded twisted-pair cables. The module features a green LED for backplane power status. Furthermore, its conformal coating protects against dust and light moisture.
