DESIGO building automation system

DESIGO TX-I/O module
DESIGO TX-I/O modules, which provide the interface to the devices at the field
level, the sensors and actuators. They communicate with connected DESIGO PX
modular automation stations and can be interconnected in application-specific
configurations.
A space-saving, flexible product range of compact TX-I/O modules is available for
signalling, measuring, metering, switching and positioning. The I/O module system is
DIN compliant in design and optimized for panel mounting and supports
decentralized, remote module installations.
The TX-I/O modules have LEDs or optional LCD displays with signal and warning
display programs to indicate the state of the plant and can be manually or
emergency operated depending on the module type.
The integrated isolating-terminals facilitate the hardware test carried out during
commissioning.
The combination of DESIGO TX-I/O modules with proven PTM modules within a
plant is also possible without a problem.
For the user, the advantages of the DESIGO TX-I/O modules are as follows:
• Integrated isolating-terminal feature.
• Integrated manual controls (optional).
• Integrated diagnostics functions with LED and
optional LCD display.
• Optimized for HVAC actuators and sensors.
• DIN compliant construction optimized for panel
mounting.
• Self-connecting bus connection for the easiest
possible assembly.
• Lean, flexible product range for
optimized logistics.
• Clear text module labeling.
• Tool support for configuration,
diagnostics and function test.
• Third-party integration with DESIGO TX
OPEN modules for Modbus, M-bus
meters and variable speed drives
(Siemens SED2).
DESIGO TX-I/O modules with integrated isolating terminals and optional manual operation
You can integrate third-party integration, for example, pumps (GRUNDFOS, WILO),
compact air conditioning units (MENERGA), M-bus meters, and variable speed
drives in a decentralized and economic manner. Access to the following information
is available, for example, when pumps are connected:
• Control operating mode
• Setpoint adjustment
• Fault and status codes
• Delivery head
• Power
• Speed
You can also use the DESIGO PTM module together with the series PXC…-U
modular automation station.
