The Helmholz GmbH Analog-input-module for the modular fieldbus IO system TB20 and the module has 2 to 4 analog inputs for RTD resistance measurements, depending on whether the wiring is 2 or 3 or 4 wire also has 2/4 inputs for measuring resistance, electrically isolated from the backplane bus. Diagnostic messagesWire break detectionA bi-color LED indicates the module operating status and any malfunctions

The Helmholz GmbH bus coupler is designed to connect a PROFIBUS bus to TB20 peripheral modules and it supports the DP-V0 and DP-V1 protocols also it will recognize all connected peripheral modules and assign each module the corresponding inputs/outputs from the process image table. A functioning TB20 configuration will always require a bus coupler and at least one peripheral module, but can accommodate up to 64 modules of any kind connected in series with the bus coupler. Supports all PROFIBUS baud ratesDP-V0 and DP-V1 supportUp to 64 peripheral modules

The Helmholz GmbH power and isolation module serves as a power supply module for the power bus 24 V DC, GND and AUX to the right, while segmenting the power bus on the left and this module can be used to subdivide a power bus into individual segments. Segments the power bus to the leftA green LED indicates the 24 V DC statusA blue LED indicates the module's operating status

The Helmholz GmbH Digital-output-module for the modular fieldbus IO system TB20 includes the appropriate front connector for the cabling and a base module and the module has 16 digital outputs. A blue LED indicates the module's operating statusGreen LEDs indicate the inputs’ statesElectrically isolated from the backplane bus

The Helmholz GmbH potential distributors simplify the wiring work and expand the connection options and the 4x DC 24 V + 4x GND potential distributor makes the 24 V DC supply and the GND connection from the power bus available on the front connector. Maximum 8 A supply loadPowers outputs using the power busA blue LED indicates the module's operating status

The Helmholz GmbH active drop cable PROFIBUS is used for easy connection of a PG to an existing PROFIBUS network and due to the integrated electronics, it is not a stub. Cable length 3 m

The Helmholz GmbH potential distributors simplify the wiring work and expand the connection options and the 9x free potential distributor makes 9 contacts that are connected to each other available on the front connector with the potential distributed through these contacts can be freely chosen.
