Siemens 505-6108A 505-6208 Analog Input Module

Products Description

 

The Siemens 505-6108A 505-6208 Analog Input Module (also referenced as PPX:505-6108A) is a high-quality analog I/O module from the legacy SIMATIC TI505 PLC family. The 505-6108A 505-6208 provides 8 independent analog input channels capable of measuring voltage and current signals from industrial sensors and transducers. This module translates field analog signals (such as ±5 V, ±10 V, or 0–20 mA) into digital data that the PLC controller can process for monitoring, control, and automation tasks. The input module translates an analog input signal from a monitoring device into an equivalent digital word and transmits that data to the controller for processing.Designed for rugged industrial use and seamless rack integration, the 505-6108A 505-6208 is ideal for process control, machine monitoring, and other applications requiring accurate multi-channel analog measurement.
