Siemens 505-6108B Channel Analog Input Module

Siemens 505-6108B Channel Analog Input Module   

Product Details Introduction

Siemens 505-6108B 8-channel analog input module

Belonging to Siemens SIMATIC 505 series PLC, 8-channel single ended analog input module, model 505-6108B.

Support signals: ± 5V (default), ± 10V (jumper setting), 0-20mA current, compatible with all channels.

The resolution is 13 bits+sign bit, with a resolution of 0.625mV at ± 5V and a resolution of 2.5 μ A from 0-20mA.

Adopting successive approximation SAR conversion, the full channel conversion speed is fast, with a maximum of 25ms, and the acquisition is stable and efficient.

The current input has a built-in 250 Ω high-precision resistor, which can be directly connected to a 0-20mA transmitter without the need for an external resistor.

Equipped with overvoltage, overcurrent, and internal clamp protection, powered by the backplane, no additional external power supply is required.

Each channel occupies 1 word address, and 8 channels occupy a total of 8 WX word addresses, making programming simple and intuitive.

Compared to 505-6108A, version B has higher accuracy, faster speed, and overall improved performance.

It is recommended to use shielded twisted pair cables for wiring, separating analog and power lines to reduce interference and improve accuracy.

Widely used in industrial analog signal acquisition scenarios such as pressure, flow rate, liquid level, temperature, displacement, etc.

In summary, Siemens 505-6108B is an 8-channel analog input module with high precision, speed, and reliability, which is particularly suitable for the maintenance, renovation, and replacement of old SIMATIC 505 control systems. It is a stable and reliable analog acquisition solution for industrial sites.
