EN6000B9 Alarming Ancilliary Module

    An EN6000B9 module can receive the control alarm state from communication systems to retransmit communication and the remote transmission alarm functions, and coordinate across different communication speeds. The different communication addresses can be set so as to carry out multi-module extensions. Its circuit is simple and reliable. It can be used to extend the alarm function of an industrial control computer or a DCS system, and to connect with an EN6000B6/B6C series instrument (unified alarm type only).

Wiring


Function Characteristics

The whole isolation method (power supply isolation, the isolation between the front end input and the back end output) is used to ensure the anti-interference ability of the signal from the external communication. Any direct electric connection is avoided to stabilise the anti-interference capability.

A voltage or contact switch input mode has been replaced by a communication alarm mode. The circuit of a module is simple and reliable and the module parallel additions can be implemented.
