The gas control unit with Modbus® communication is a central unit for gas detection systems in residential and commercial buildings, such as apartment blocks. By communicating with concentrator modules (ACIM01), the MASTER control unit acquires the contact status of the output relays of residential gas detectors. It can manage up to 32 ACIM01 concentrator modules (SLAVE). Up to 4 zones can be combined, each connected to 4 to 8 concentrators.
The unit has 5 voltage-free changeover contacts (4 alarm relays + 1 auxiliary relay) and password-protected installer parameter management. It is suitable for 8-module DIN rail mounting.
