5.3. functions
The following control tasks can be executed with the process con-
troller Type 8611 eCONTROL.
• Fixed command control (single-loop control circuit)
• Sequential control (external set-point value)
• Ratio control
• Cascade control
Standard signals (current / voltage) and frequency-analog signals
can optionally be applied or resistance thermometers (Pt 100) can be
connected to the scalable controller inputs.
Outputs for continuous standard signals (current / voltage) or tran-
sistor outputs can be used as controller outputs. Valves or other
switching actuators can be operated via the transistor outputs. One
binary output and up to 2 binary outputs for auxiliary functions are
additionally provided.
5.4. The various mounting and
installation models
The process controller Type 8611 is available in the following
models (see also chapter “7.1. Assembly models”):
• For installation in a pipeline system
• For attachment to a proportional valve
• For wall assembly or for assembly on a rail
• For installation in a control cabinet
