Modular bus coupling unit and flush-mounting actuator
A key feature of the GAMMA instabus is its uniform bus coupling unit. The bus transceiver module (BTM) can be used as a stand-alone unit, as
well as a combined version in various devices of the flush-mounting actuator range.
Implementation of the BTI interface (Bus Transceiver Interface) with the bus transceiver module (BTM) ensures maximum flexibility and an
impressive range of functions. Bus coupling units (BTM) and flush-mounting actuators with integrated bus transceiver modules (BTM) enable the
use of GAMMA display/operator interfaces, such as pushbuttons, room temperature controllers and operation units in a wide range of designs.
Thus, all GAMMA instabus operator interfaces with BTI interface in the design lines i-system and DELTA style can be combined with either a bus
transceiver module (BTM) or a flush-mounting actuator with bus transceiver module (BTM).
This reduces planning work and facilitates installation and commissioning. The application programs of the flush-mounting actuators are identical
to those of the functionally equivalent devices from the modular room control range. This means that all devices have the same standard applica-
tion program – regardless of mounting type – whether flush-mounting, with or without mounting frame – or whether designed for installation in
the room control box and automation module box.
