What are Electrical Interface Modules?
Electrical interface modules are devices used to connect input/output (I/O) signals from field devices to control systems like PLCs (Programmable Logic Controllers) and DCS (Distributed Control Systems). They help convert, isolate, or condition signals to ensure reliable and safe data transmission.
Key functions include:
- Signal conversion and isolation
- Surge and overload protection
- Simplified wiring for complex systems
- Improved efficiency in troubleshooting and maintenance
They are widely used in automation, energy, transportation, and building management systems.
