TAC Xenta 400 I/O modules Foreword

Foreword

This handbook describes the I/O modules of the TAC Xenta 400 family.

The descriptions of these were previously included in the manual “TAC Xenta 400 Handbook”, but as the handbooks for the TAC Xenta 300 and 401 were merged, the sections describing the I/O modules were assembled in a separate manual. The purpose of this is to simplify adding new modules to the new manual.

In edition -1, the units TAC Xenta 471 Analogue input module and TAC Xenta 491/492 Analogue output modules were added.

In edition -2, technical data (ambient temperature) and part numbers for the units TAC Xenta 421XT and 422XT were added.

2.1 Hardware units

The TAC Xenta freely-programmable controllers consist of the following units.

• The TAC Xenta 301/302/401 controller. The controller is the brain of the system. It contains the database of the inputs and outputs of the plant. It also contains the system and application software for all the functions that are to be performed by the controller and connected peripheral units.

• I/O expansion modules, which provide the inputs and outputs of the TAC Xenta controller.

• The TAC Xenta OP is an easy-to-use operator panel, with a display. The values are presented in plain language in a menu system. The OP can be connected to any controller in the network.

A number of controllers and I/O modules can form a local network and exchange data.

The TAC Xenta OP operator panel is used to give the user access to certain parameters and make it possible to present alarms without communicating with a central system. The most important functions of the operator panel are status monitoring, adjustment of setpoints and time channels and the display of alarms.

A maximum of two OPs may be connected to each controller.

TAC Xenta 400 I/O modules 2 I/O modules in the TAC Xenta 400 series

The I/O modules are used as expansion modules for the TAC Xenta controllers, connected to these via the common TP/FT-10 network.

The modules have different I/O configurations to suit different applications. Some models have indicators for the digital input status and a manual override for the digital or analog outputs. An overview of the available models is shown below.

2.2 Configurations

The I/O modules of the TAC Xenta 400 series can be used in different configurations, for example:

• Together with a stand-alone controller.

• With controllers and OPs in a network.

• Controllers, OPs, I/O modules and other equipment in a full network with suitable adapters, possibly connected to a TAC Vista Central System.

For further information, please consult the “TAC Xenta Network guide”.

Restore to default values

If you press the Service Pin for seven seconds during the first minute following a restart, the parameters of the module will be restored to the factory default values. A restart occurs following power on.

The green LED on the front will light continuously during activation (about 7 seconds) and when the restore has finished, it will flash rapidly (off-line indication).

The parameters of the I/O module will now be restored:

• Domain table index 0: ID len = 1, ID = 11

4 Installation

4.1 Mounting

The TAC Xenta controllers and I/O modules are designed for mounting on a DIN rail inside a cabinet. They can also be mounted directly on a wall. In such cases, a wide range of standard enclosures are available which meet DIN 43 880, with different enclosure ratings.

The enclosure mainly consists of a terminal part containing screw terminals, as well as an electronics part, where the printed circuit boards are situated. The enclosure is designed so that electrical installation can be carried out using the screw terminals of the terminal part, when mounted on a DIN rail or wall.

4.2 Electrical installation

4.2.1 General considerations

Installation is normally treated as category CAT III (IEC 664), which in principle means permanent connection to a 230 V AC mains supply. For the Xenta 400, this is only applicable to the relay outputs of the I/ O modules.

All equipment connected to the TAC Xenta units must comply with the following standards:

- EN 60 742 (or other relevant safety standard; for example ETL listing UL 3111-1, first version and CAN/CSA C22.2 No. 1010.1-92) for the device(s) that provide an ELV-type power supply (normally 24 V AC) to the controller and other connected equipment.

- EN 61 010 or IEC 950 (or other relevant safety standard) for computers, modems and other equipment powered by a 230 V mains supply.

If equipment using a 230 V mains supply is connected to a relay output terminal of the I/O modules, low-voltage equipment connected to the other relay terminals of the controller must provide at least basic insulation to all touchable parts.

We strongly recommend that switches are installed to make it possible to separate external equipment when the relay output terminals control equipment using a 230 V mains supply.

4.2.2 Terminals and units

• Mount the terminal part on a DIN rail.

• Connect the cables to the correct terminals, see the figure below.

• Put the electronics part of the module on the terminal part.

Connections

When cabinet mounting is used, jumpers may be used between M (measurement neutral) terminal pairs, as shown in the figure below and on the next page. All G0 points must be connected to protective ground.

TAC Xenta 400 I/O modules 4 Installation

When connecting G0 to ground, each TAC Xenta unit must have its own connection to the ground rail, i.e. jumpers cannot be used for the G0 terminals. Please refer to the figure on the next page.

Several units may share the same ground rail, but every unit with measuring inputs and/or analog outputs must have all its ground connections with the same ground rail.

In other words, a discontinuation in the ground rail must not split a controller or separate it from the connected units.

4.3 Commissioning

Commissioning of the I/O modules is always carried out together with the base units (TAC Xenta controllers) that they belong to.

The procedure is therefore described in the TAC Xenta 300 and 401 manuals.
