4 Product overview and description
4.1 Technical features
The system features of the DAC-4x(A) are the following:
• One differential command input (set point). Range of 0 ± 10 respectively 0 or
4 ... 20 mA, resolution 16-bit.
• Two single ended command point inputs. Range of 0 ± 10 respectively 0 or
4 ... 20 mA, resolution 16-bit.
• Two single ended feedback inputs. For current and voltage. Wide range of adjustability, resolution 16-bit.
• Two optional inputs for LVDT signals. 1 or 2 inputs with optional extension board; information on request.
• Integrated reference voltage supply of ± 10 V (10 mA max.), to supply set point potentiometer or actual value
transducer.
• 4 (optional 5) recallable digital adjustable set points.
• Direction externally set through “+“ and “-“ inputs.
• Enable signal for output stages.
• Reset-Ramp for fast ramp function zeroing.
• Status outputs "error“ and "comparator“.
• All digital inputs and outputs are optically isolated for functional security.
• Display with four 7-segment indications and six keys for easy handling and operation.
• Function indication through front panel by LEDs.
• Additional switching output (24 V, max 1A) to directly disable safety valves.
• Analog outputs to perform controller functions and / or enable subsequent electronic devices and monitoring
(± 10 V, 12-bit resolution). One is also selectable as current output 4 ...20 mA.
• Additional front panel test jacks (2 mm) for easy commissioning. Test jacks for set point (SET)*1, for feedback 1
(FB1), for solenoid currents (A) and (B) and monitor input (MON) display for analog display of all parameters
(± 10 V, 12-bit resolution).
• USB interface with USB-C connector
• Serial interface RS232 (instead of USB_C interface; optional on request)
• Optional available: PROFIBUS, PROFINET, ETHERNET/IP and CANopen interfaces available.
