Siemens 505-6108A Analog Current Module

Siemens PPX:505-6108A is an 8-channel analog input module for the TI505 family that accepts voltage or current signals from field sensors, enabling the TI505 controller to monitor processes such as pressure, temperature, flow, and position. The A revision provides 12-bit resolution across its eight channels, with input options including current (4-20 mA) and voltage signals in ranges such as 0-5 V or ±5 V, depending on configuration. Compatible with TI505 hardware, this module serves as the bridge between sensors and the controller, allowing direct conversion of analog signals to digital values for PLC programs. The 505-6108A is paired with its sibling 505-6108B variant, the latter offering 13-bit resolution and related features; both belong to Siemens' 505 Analog I/O Module family and share common wiring and mounting practices for single-wide TI505 backplanes.
