3AM374.6 Product Description

The B&R 3AM374.6 is a versatile analog mixed module designed to cater to a broad range of industrial automation needs. This module is an integral component of the B&R SYSTEM 2005 and is engineered to provide precise analog signal processing capabilities. It features four inputs that can be configured to accept either voltage signals from 0 to 10 V or current signals from 0 to 20 mA, offering flexibility for various sensor types and signal ranges.

Additionally, the 3AM374.6 module boasts four outputs that are capable of delivering either ±10 V or 0 to 20 mA signals, making it suitable for controlling actuators or interfacing with other control systems. The outputs can be adjusted in pairs, allowing for customised configurations based on specific application requirements.

The module's technical specifications include a 12-bit digital converter resolution, ensuring high precision and accuracy in signal conversion. It also features electrical isolation between channels and the PLC, enhancing system reliability and reducing the risk of electrical interference.

For ease of monitoring and diagnostics, the 3AM374.6 is equipped with status LEDs that provide visual feedback on the module's operation, including power, configuration, and signal status. The module's compact design is compatible with the B&R 2005 main and expansion racks, ensuring seamless integration into existing systems.

With its robust construction and reliable performance, the B&R 3AM374.6 analog mixed module is an excellent choice for industrial applications that require accurate and reliable analog signal processing.

Frequently Asked Questions

What type of module is this?

This is an analogue mixed module designed for handling both input and output functions in industrial automation systems.

Can the input and output signals be configured?

Yes, the module allows for the configuration of input and output signals. Each group of two channels can be configured for either voltage or current signals.

What are the input and output signal ranges for this module?

The input signal range can be set to 0 - 10 V or 0 - 20 mA, while the output signal range can be configured for ±10 V or 0 - 20 mA.

Is there any isolation between channels on this module?

There is electrical isolation between the channels and the PLC, but there is no channel-to-channel isolation.

What operating modes are available for this module?

The module features several operating modes including normal operation, special operating mode 1 with direct software timing, and special operating mode 2 with software timing using a predefined time.

How does the module indicate its status?

The module has status LEDs that provide visual indications of its operational status, including whether it has been configured and the type of signals configured for each channel.

What should be considered when wiring the module?

It is recommended to use shielded cabling for the analog input and output signal cables, and to ensure proper grounding of the shields to avoid electromagnetic interference.

How is the module mounted?

The module is designed to fit into a B&R 2005 single-width mounting rack, which is a standard size for B&R automation systems.

Can the module's configuration be changed during operation?

No, the configuration of the module is retained across operating modes and cannot be changed during operation. It should ideally be configured during the initialisation phase of the system.

What is the conversion time for the module's channels?

The conversion time for all channels in normal operation is less than 1 ms, and less than 1.5 ms if averaging is active.
