TAC Xenta 411/412

Digital Input Module

TAC Xenta 411 and 412 are Digital Input modules in the TAC Xenta family. They are used as expansion modules for the TAC Xenta controllers, connected by the common network.

Both modules have ten digital inputs and these inputs can also be used as pulse counters.

In addition, TAC Xenta 412 is equipped with LED status indicators, one for each digital input. The LED colors, red or green, are individually selectable through switches under the front cover.

TAC Xenta 411/412 is associated with a specific controller with the assistance of the TAC Menta® graphical tool.

If there are several controllers and I/O modules in the same network, a special Device Configuration Tool PC program is used during the commissioning phase.

The digital input status can be checked from the TAC Xenta OP operator panel connected to any TAC Xenta controller in the same network. TAC Xenta OP has a display and a minimum number of push buttons for taking readings and altering settings.

Design

TAC Xenta 411/412 consists of a terminal and a circuit board mounted together (figure 1). All terminations of field wires are made to the terminal part only. Thus, the electronics part may be removed for service without affecting the terminal connections.

Digital Inputs

The ten Digital Inputs are used to sense alarm contacts, status indications, pulse counting, etc.

Each digital input can be used as a pulse counter (e.g. flow measurement).

Another application is alarm monitoring. Each time an alarm is tripped, the corresponding counter can be arranged to increment, providing data for operating statistics.

The Digital Input circuits are internally powered.

LED indicators

There are two general LED indicators on the front of the module. One is red and lights up if there is a hardware fault. The other is green and blinks to indicate that the application program is running.

TAC Xenta 412 is equipped with ten status indicators, one for each digital input. The corresponding LED lights up when the input status is ON.

The LED colors, red or green, are individually selectable through switches under the front cover.

Mounting

TAC Xenta 411/412 is cabinet mounted on a TS 35 mm norm rail EN 50022. The Digital Input module consists of two

parts; a terminal with the screw terminals, and an electronics with circuit boards. To simplify installation the terminal can be pre-mounted in the cabinet (see figure 1).

If the module is wall mounted, a range of standardized boxes are available.

Cables

G and G0:

Min. wire size of 0.75 mm2 (18 AWG).

C1 and C2:

The TP/FT 10 allows the user to wire the control devices with virtually no topology restrictions. The max. wire distance in one segment depends on the type of wire and the topology. For normal applications, using the Belden 85102 cable, the distance may be up to 500 m (1640 ft.). For other applications,­ please refer to the TAC Xenta Network guide.

The wires are polarity insensitive, but must be a twisted-pair.
