ABB Freelance 2000 Instructions for Contrans I

which greatly improves the accuracy and stability of signal processing and ensures stable system operation. 

When dealing with complex industrial signals, it can optimise the processing of different types and strengths 

of signals to reduce signal interference and distortion.

Hardware design features

Separate design: Adopting the innovative design of separating the electronic function module from the junction box. 

In the installation process, the standard junction box is fixed on the DIN mounting rail to complete the wiring before inserting the function module,

 which greatly reduces the difficulty and probability of error and improves the installation efficiency.

Multiple Backplane Types: V17111-321, -322, -351 and V17111-320 backplanes are available. 

Each of these backplanes has its own characteristics in terms of signal processing capability, power supply mode, interface type, etc.

For example, some of the backplanes support redundant power supply, which can meet the diversified needs in different industrial scenarios.

Electrical isolation and safety features: excellent electrical isolation performance, in line with relevant safety standards.

 There are high isolation voltages between the system connection and the field connection, as well as between the module slots, effectively preventing electrical interference and guaranteeing system operation safety. Polarity protection and fuse monitoring are also provided to enhance the stability and reliability of the system.

Functional diversity

Abundant input and output modules: There are a variety of digital and analogue input and output modules,

 covering different channel numbers and functional characteristics. 

The digital input modules are available in 16-channel32-channel and other specifications, and some of them are equipped with fault signal monitoring and redundancy functions;

the analogue input modules support a variety of signal types, 

and the analogue output modules are equipped with short-circuit protection for outputs, which can satisfy the needs of various industrial control scenarios.

Supports HART and FSK buses: Compatible with HART and FSK buses, 

efficient communication is achieved through a pluggable FSK bus amplifier. 

Up to 100 16-channel or 50 32-channel backplanes can be connected,

 which facilitates data interaction with smart transmitters and other devices and enhances the intelligence of the system.

Convenience and cost-effectiveness

Easy to install: The unique plug-and-play design makes installation and maintenance extremely easy.

 When installing, there is no need for complicated wiring operations, just follow the process;

 when maintaining, directly replace the functional modules without rewiring, reducing maintenance time and costs.

Reduced system complexity: When used with Freelance 2000, the number of I/O boards can be reduced, simplifying the system architecture.

 It can be used as a cross-wiring/field terminal, reducing the complexity of system design and implementation, 

and improving overall system reliability and maintainability.
