The WAGO 750-472 is a 2-channel analog input module designed for the WAGO-I/O-SYSTEM 750. It is used to capture current signals from field devices, convert them into digital values, and transmit them to a controller. The module supports current signals from 0 to 20 mA and provides single-ended inputs

The WAGO 750-555 is a 4-channel analog output module for the WAGO-I/O-SYSTEM, which is a modular, fieldbus-independent system for industrial automation. It generates standard 4–20 mA signals with a resolution of 12 bits. Key specificationsAccording to the WAGO and RS India websites, the WAGO 750-555 features the following specifications: 

• Module type: 4-channel analog output module
• Analog outputs: 4 channels, 4–20 mA
• Resolution: 12 bits
• Connectivity: 2-wire actuator connection via CAGE CLAMP® terminals
• Mounting: DIN rail (35 mm)
• Dimensions (W x H x D): 12 x 100 x 69.8 mm
• Operating temperature: 0 °C to +55 °C
• Conversion time (typical): 10 ms
• Isolation: 500 V system/field
• Power supply: Derived from the field side

This fieldbus coupler connects the WAGO I/O System as a slave to the PROFIBUS fieldbus.

The fieldbus coupler detects all connected I/O modules and creates a local process image. This process image may include a mixed arrangement of analog (word-by-word data transfer) and digital (bit-by-bit data transfer) modules.

The process image can be transferred via the PROFIBUS fieldbus to the memory of the control system.

The local process image is divided into two data zones containing the data received and the data to be sent. The process data can be sent via PROFIBUS to a control system for further processing. The process output data is sent via PROFIBUS.

The data of the analog modules is stored in the process image that is created automatically according to the order in which the modules are connected to the coupler. The bits of the digital modules are sent byte by byte and added to the analog data. If the amount of digital I/O information exceeds eight bits, the coupler automatically starts with a new byte.

The WAGO 750-430 is an 8-channel digital input module designed for receiving control signals from digital field devices like sensors and proximity switches. It is part of the WAGO 750 Series I/O System, and its narrow, 12 mm width allows for a high channel density. Product features
