voltageflowcurrent

• Ordering method and detailed technical information are in the catalogue card and manual, control, monitoring, and recording of temperature and other physical values (humidity, pressure, level, flow rate, speed, etc.) processed into a standard electric signal (0/4÷20 mA, 0÷10 V, 0÷60 mV, 0÷850 Ω), with the option of presenting 1 to 4 measurement channels, • 4 universal inputs (thermoresistance and analogue, no galvanic separation) with the option to create inter-channel mathematical formulas such as: difference, average, sum, larger, smaller from measured values; • 4 control/alarm outputs with independent control algorithms: ON-OFF with hysteresis, PID, PID autotuning, 12-step program adjustment • an optional module of 4 analogue outputs (0/4÷20 mA and 0/2V÷10V) and 5 functional binary inputs (BIN) to change the operating modes of the associated outputs (control start/stop, selection of the day/night set value, manual/automatic mode); the analogue outputs are logically connected to the two-state outputs (P/SSR) and are used for control or retransmission of measurements and set values; the inputs and the outputs have no galvanic separation (common ground); • selection of setpoints for outputs from: 2 defined for each output, the common value from the 1st output (without and with offset for 3-position control), from the selected program or any measurement input; • selection of independent PID sets (from the 8 available sets) for individual setpoints (gain scheduling); • advanced automatic PID parameter selection function with fuzzy logic elements for each of the outputs;
