This manual provides installation, wiring, configuration, and operation instructions for the Eaton NRX Series PROFIBUS DP Communication Adapter Module (PCAM).
The Eaton NRX Series PROFIBUS DP Communication Adapter Module (PCAM) is a communication accessory designed for use with NRX Series trip units/circuit breakers. It operates as a slave device on a PROFIBUS DP master station network using the PROFIBUS-DP-V0 protocol. The module enables control commands for tripping, closing, and resetting the circuit breaker, as well as monitoring power and residual current status. It requires a 24V DC power supply and is designed for DIN rail installation. This manual is written in Chinese.
