1771-WA

The 1771-WA field wiring arm, also commonly referred to as a wiring base or terminal block, is a hardware device used in industrial automation control systems to connect a PLC (programmable logic controller) to an external device or sensor. These devices play a vital role in the control system as they provide the electrical interface from the PLC to the actual physical device.
The field boom typically has multiple terminals that allow the user to connect a cable or wire to the input/output (I/O) module of the PLC. With the correct wiring, the PLC can read the signal from the sensor and control the operation of the actuator, motor and other equipment.
Field connection arms are often designed with ease of use, reliability, and safety in mind. They may have markers or indicators to help users connect wires correctly and may contain protective mechanisms such as short-circuit protection or overload protection to prevent potential electrical failures.
When using the field boom, the manufacturer’s installation guidelines and best practices need to be followed to ensure the accuracy of the connection and the stability of the system. Incorrect wiring can result in signal interference, system failure, or even equipment damage.
In general, the field wiring arm is an integral part of the industrial automation control system, they ensure the electrical connection between the PLC and the external equipment, thus achieving effective control of the entire system.
