Series 6495 TROVIS 6495-2 Industrial Controller

For panel mounting (front frame 96 x 96 mm/3.78 x 3.78 inch)

Application

Digital controller to automate industrial and process plants for general and more complex controltasks · Suitablefor control of continuous, on/off or pulsing final control elements (pneumatic actuators with i/p positioners, electric actuators, electric heat ing systems, refrigerating machines etc.)

The TROVIS 6495-2 Industrial Controller has two independent internal controllers with common input and output sections.

By setting theconfigurationitemsandparameters,thecontroller can be adapted to a control task quickly. Preset basicconfigura tions for each control type minimize setup work for standard ap plications. The controller can be set up directly at the controller or using the optional TROVIS-VIEW software.

The controllersettings are saved in a non-volatile memory, even when the power supply fails. The two internal controllers can be operated directly without switching over. The plain-text display (German, English, French) facilitates configuration and parameterization.

the case are used to initially select current or resistance in puts. The signal type is set depending on the configuration: 0 (4) to 20 mA, 0 (2) to 10 V, Pt 100, Pt 1000; input 2 addi tionally for potentiometer.

Four digital inputs (DI 1 to DI 4) · The digital inputs are con

trolled either by a 24 V DC voltage signal or by the transmit ter supply using a floating contact. The digital outputs can only becontrolledingroups, with DI 1 andDI 2 being the first group, and DI 3 and DI 4 being the second group. Example: internal supply for digital inputs DI 1 and DI 2, and external supply for digital inputs DI 3 and DI 4.

depending on the configuration: 0 (4) to 20 mA, 0 (2) to 10 V. Outputs AO1 and AO3 can optionally be used for other signals as well.

Seven digital outputs · Four relay and three transistor outputs

The relay outputscanbeused to implement on/off, three-step (SO1 and SO2) or limit outputs (DO 1 to DO 4). The transis tor outputs DO 5 and DO 6 can be used to issue status alarms; fault alarms can be issued at transistor output DO 7.

Supply voltage

The controller comes with two different power supply units. Specify the required version in your order:

85 to 264 V AC

Supply output (auxiliary voltage)

A maximumof four two-wire transmitters and four digital inputs can be supplied by this output (21 V DC, 90 mA).

Infrared interface (Fig. 2) Data are transmitted between the controller and the

Operation

Display and operating controls (Figs. 4)

The device has nine operator keys, of which three are assigned to each controller.Depending on the selected control mode, one or two controllers are activated. Controller [1] is displayed and operated on the left, Controller [2] on the right, or optionally vice versa. The row of keys in the middle is used for both controllers.

Operating level

After the supply voltage has been switched on, the controller is in the operating level.

The readings of the controlled variable, the reference variable and the manipulated variable for each controller as well as a bar graphfor error areindicated on the display(1). Depending on the configuration, status alarms of the digital inputs and out puts can be shown. The operating menu allows set points to be switched and control parameters to be changed.

The two rows at the bottom of the display can be assigned as de sired. The user can choose between various signals and inter mediate calculationsinside the controller. For example, the val ues or a bar graph of two outputs in split-range operation can be displayed.

Configuration and parameterization

In theconfiguration level, the controller is adapted to the control task to becompleted. The functions are arranged in hierarchical menus. All settings are displayed as plain text.
