1.2 Contents of this document

The TX-I/O modules support most types of I/O signal from the UNIGYR, VISONIK and INTEGRAL legacy systems with exactly the same type of signal (functionality). Some rarer types of signal are not supported, or supported only partially.

This document describes some possible ways to proceed in such cases.

– Using other signal types, in order to use the TX-I/O modules and/or

– Using third-party equipment The solutions provide help for the following business case:

Existing field devices (periphery) shall remain in place. They are connected to TX-I/O modules which communicate with a DESIGO, UNIGYR or VISONIK automation station via P-Bus. The solutions can also serve as training documentation for engineers who are experienced with legacy systems and want to engineer a new plant with TX-I/O modules.

suitable for mounting relays on standard rails • In addition to the RT types, types RX1, RY2 and MSR are also suitable.

These are not available for all input voltages but they have a lower current consumption.

Relays from other manufacturers: The contacts must be suitable for extra-low voltage. Use interface relays, not installation relays. Only the former ensure safe isolation between core and contact in accordance with VDE0160/EN50178 for low voltage circuits (SELV or PELV) in relation to hazardous current circuits.

2.9 Overvoltage of DC 0...10 V signals

A fault message is sent if the process value is outside the range of -1.5...11.5 V. This may be the case of certain DC 0...10 V signal converters. This message cannot be suppressed. The fault message can be avoided by connecting a Zener diode. However, real faults can no longer be detected as well.

• The first UA9 (the master) is needed to convert DC 0…10V into a phase-cut DC 0…20 V signal.

• The other up to three modules (slaves) together supply a maximum of 120 VA. • As the "V " terminals of a universal or super universal module deliver only 4A,

a separate AC 24 V transformer is needed to feed four UA9 devices. It must NOT be earthed (earth loop).

• Use the connection diagram below – the diagram in the data sheet N5133 is incorrect!

3.6 NKDG, NKDW, transducer modules

The transducer modules transmit voltage signals 1:1 from input to output or from output to input without electrical separation. In addition, they have a field supply terminal for active sensors / transmitters / actors: • NKDW: AC 24 V • NKDG: DC 15 V • TX-I/O Universal or Super universal module;

Supply of the active sensors / transmitters / actors from terminal "V ". Configure U10 (input) or Y10S (output).

3.7 Special "safety interlock" option (This option is also known as "forced control")

The NK output modules are fitted with "safety interlock" terminals. • This enables the signal from the controller to be overridden via an external

contact. • If the "OFF" terminal is switched to SGND voltage via the external contact, the

signal output goes to OFF or 0%. • If the "ON" terminal is switched to SGND voltage via the external contact, the

signal output goes to ON or 100%. • For modules with a manual switch (NKOxH) the manual switches takes priority

over the safety interlock. For migration of the safety interlock function, the states of the ON/OFF contacts must be transferred via digital input data points. These must be linked to the appropriate output data point in the application.
