Introduction

The BC9191 is a room controller in a compact design with decentralized intelligence.
The integrated digital and analog connections already cover the typical standard functionalities of room temperature control.
The K-bus interface enables extensions from the entire signal spectrum of the Beckhoff Bus Terminal system.
Two Ethernet interfaces are available for communication with a higher-level master computer or other BC9191s.
Furthermore, an additional sub-bus is available with both variants of the BC9191:
Variants of the BC9191
The BC9191 is available in two variants. These differ by the sub-bus, the memory extension and the cycle time.
- The variant BC9191 provides a CAN bus for connecting the KL6583 EnOcean transceiver.
- The variant BC9191-0100 provides an RS485 interface for the efficient connection of room control units.
