EXPANSIONS

Tpa expansions, connected to the fieldbus coupler through an efficient synchronous serial protocol, allow configuring the fieldbus node according to the local connection needs of sensors and actuators. The actuable expansions may include digital I/Os (equipped with led indicators and short-circuit safety system), analog I/Os, counters, and so forth.

The expansion modules are all identical despite the different types of communication; the protocol features of the various fieldbuses are in the couplers.

TRS-IO-E

code TRS1.0.01

TRS-IO-E is an expansion unit belonging to the TRS series, designed to be mounted on DIN rails.

Its interface towards the coupler consists of a TRS bus; this means that, for it to function, the module needs to be connected through that bus to a TRS coupler. Each module is equipped with 16 bidirectional digital I/O lines. Each line is configurable either as input or as output.

TRS-IO-E is in compliance with the EMC directive 2004/108/EC.

INPUT FUNCTIONS

  • Synchronous input sampling with constant delay;

  • False up to 10 Vdc, True starting from 18 Vdc;

  • voltage absorbed by each input: 3 mA.

OUTPUT FUNCTIONS

  • 0.5 A highest voltage per output;

  • output overload and overvoltage safety (36 V);

  • real-time output re-reading (software diagnostics);

  • output activation synchronous with communication on TRS bus.

TRS-AN-E

code TRS1.0.02

TRS-AN-E is an expansion unit belonging to the TRS series, designed to be mounted on DIN rails.

The interface towards the coupler consists of a TRS bus, that means that, for it to function, the module needs to be connected through that bus to a TRS coupler. TRS-AN-E manages one analog input (16 bits), one analog output (16 bits), and it dialogues with a coupler and other expansion units connected to the same TRS bus. TRS-AN-E includes a programmable precision gain amplifier, useful to implement the different types of measuring tools.

TRS-AN-E also includes a precise voltage reference. TRS-AN-E is in compliance with the EMC directive 2004/108/EC.

ANALOG OUTPUT

  • One +/-10 V differential analog output line, 16-bit resolution and 15 mA maximum voltage.

ANALOG INPUT

  • One +/-10 V  differential analog input line, 16-bit resolution;

  • low-pass filter at 7 kHz.

I/O PORT FUNCTIONS

  • Synchronous input sampling with constant delay;

  • False until 10 Vdc, True starting from 18 Vdc;

  • voltage absorbed by each input: 3 mA.

TRS-24-E

code TRS1.0.90

TRS-24-E is an expansion unit belonging to the TRS series, designed to be mounted on DIN rails.

The interface towards the coupler consists of the TRS bus; that means that, for it to function, the module needs to be connected through that bus to a TRS coupler.

Each module can support 8 field supply points (+24 V) and 8 points of the associated grounds, making the wiring of I/O indicators of the next TRS-IO-E expansion easier.

TRS-AC-E

code TRS1.0.03

TRS-AC-E is an expansion unit belonging to the TRS series, designed to be mounted on DIN rails.

The interface towards the coupler consists of the TRS bus; that means that, for it to function, the module needs to be connected through that bus to a TRS coupler.

TRS-AC-E interfaces a differential encoder, providing a 16-bit counting, in addition to functions like fast input, fast output, and zero-notch.

ENCODER FUNCTIONS

  • 5 V differential encoder interface, 16-bit counting and the possibility to interface with 12-V and 24-V drives, differential or not;

  • zero-notch, fast input, and fast output functions (0-24 V);

  • encoder sampling synchronized with the TRS bus, and constant delay;

  • return interface of the encoder input signals in a RS-422/TTL format, zero-notch, fast input, and fast output.

TERMINAL BLOCK IP67

CODE TRS2.0.01

The new terminal block, fully equipped with eight M8 three-pin connectors and led indicators, is now part of Tpa products, granting a good use flexibility and high standard of safety from water and dust.

It works as an extension cord for TRS modules, allowing a wiring in the machine at an IP67 safety level. Its M8 three-pin connectors let it be connected indifferently to sensors or actuators.

The IP67 safety is guaranteed both on the device and on its associated cable.
