<strong>Control</strong> elements<br />
• Analogue terminal<br />
Sensors, actuators and control elements are connected to the<br />
industrial controller used via the analogue terminal.<br />
− Inputs<br />
Pt 100<br />
Level (0 ... 20 mA)<br />
Flow (0 ... 1 kHz)<br />
S. Funct. (0 ... 1 kHz)<br />
ext. Sp. (0 ... 10 V)<br />
In Bin (0 / 24 V)<br />
<strong>Control</strong>ler input 1 'Actual value'<br />
The changeover:<br />
• Pt 100,<br />
• Level and<br />
• Flow<br />
is effected on the controller in the corresponding<br />
configuration menus or with the visualisation<br />
software<br />
<strong>Control</strong>ler input 2<br />
Configurable on the controller for:<br />
• Feedforward control<br />
• Cascade control<br />
• Sequence control<br />
• Ratio control or<br />
• External setpoint value<br />
Binary input<br />
Configurable on the controller for:<br />
• Triggering of alarm<br />
• Changeover Manual / Automatic<br />
• Changeover external / internal setpoint<br />
− Outputs<br />
<strong>Control</strong>ler output 'correcting variable'<br />
Out V (0 ... 10 V)<br />
Configurable on the controller as:<br />
Out I (0 ... 20 mA)<br />
• Steady-state output (0 ... 10 V, 0 ... 20 mA)<br />
Out B1 (0 / 24 V)<br />
• 2-Point pulse-width modulated output (B1)<br />
Out B2 (0 / 24 V) • 3-Point pulse-width modulated output (B1, B2)<br />
Out B3 (0 / 24 V)<br />
Out Alarm (0 / 24 V; 24 / 0 V)<br />
Binary output<br />
Configurable on the controller for:<br />
• Alarm signal<br />
• Error signal<br />
• Manual signal<br />
Output for alarm signal<br />
(inverted or non-inverted)<br />
