2.1 Hardware Units

Warning
The TAC Xenta 400 I/O modules and the other products of the TAC Xenta family must not be used for any other purpose than those for which they were designed.
Installation, connection and repair may only be performed by autho­rized personnel.
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-us e operator panel, with a dis- play . The values are presented in plain language in a menu system. The OP can be connected to any controller in the network.

2 I/O Modules in the TAC Xenta 400 series TAC Xenta, TAC Xenta® 400 I/O Modules
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.
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 Vi Central System.

3.6 TAC Xenta 451A/452A Universal Input and Analog Output module

The modules have eight universal inputs and two analog outputs. The universal inputs can be used as analog inputs, digital inputs or pulse counters.
The TAC Xenta 452A is also equipped with LED status indicators for each universal input (when used as a digital input) and manual override controls for the analog output values. The LED input status colors, red or green, and the polarity (lit when contact is open or closed) can be selected individually by altering the parameter settings in TAC Menta.

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.

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.

Power and Communication
G and G0 (Power supply):
G, min. cross-sectional area ...........................0.75 mm² (19 AWG)
G0 to TAC Xenta, min. cross-sectional area....1.5 mm² (16 AWG)
C1 and C2 (Network):
The TP/FT-10 system allows the user to wire the control devices with virtually no topology restrictions.
Min. cross-sectional area................................0.65 mm² (22 AWG)
The max. wire length in one segment depends on the type of wire and the topology, see the table below.
The wires are not polarity sensitive, but must be a twisted-pair. For more details, please refer to the ”TAC Xenta Network guide”.
One of the following cable types must be used:

Belden 85102, single twisted pair
Belden 8471, single twisted pair

If a shielded communication cable is us ed, the shield must be grounded at one point only.
Redundant wires (second pair of Siemens J-Y(st)Y) are cut at the end of the shield.

4.3 Commissioning

Commissioning of the I/O modules is normally carried out together with the TAC Xenta controller units that they belong to.
The procedure is therefore described in the TAC Xenta 280 - 300 - 401 manual.
However, TAC Xenta 421A/422A and 451A/452A can also be used as certified L tocol is used, some additional configuration is required. This is explained in the Configuration instructions
• 0FL-4181 for TAC Xenta 421A/422A and
• 0FL-4182 for TAC Xenta 451A/452A.
