P30O Pulse Flow Transmitter- Frequency Counter Transducer - DIN Rail Digital Indicator - Data Logger

The P30O universal rail mounting digital process indicator measures input pulses and displays the measured pulses on a 2 line backlit display. The measured data can also be data logged, recorded to SD external memory or internal storage. When operating as a flow transmitter the P30O converts input pulses to a rate of flow digital indication and retransmits a corresponding 4...20A or 0...10V output proportional to flow rate. The P30O can also operate as a counter or an up down counter. The P30O universal transmitter offers NO relay alarm contacts, auxiliary sensor power supply. Modbus and Ethernet communication options ensure easy integration and connectivity to supervisory or control systems.

P12O - Modbus RS-485 Programmable transducer for number of pulses, working hours, frequency, analog and relays output

P12O Programmable measuring transducer is designed to convert of number of pulses, number of working hours, frequency, period and rotational speed into a digital or standard current or voltage signal. The output is galvanically isolated from the input and supply. The insulation exists also between the current and voltage input. The P12O type transducer has programmable measuring and auxiliary functions. The parameter modification is possible through the PD14 type programmer, the RS-485 interface or from the keyboard. The transducer is commonly use in computer systems, e.g. with LUMEL-ENERGY program. 

Next to programmable measuring function P12O type transducer has programmable auxiliary function:
conversion of measuring value into an output signal on the base of the individual linear characteristic,recalculation on the input quantity into any indication on the base of the individual linear characteristic,programming of alarm outputs,signalling of the measuring range exceeding, recording of any input signal in programmed segments of time or event recording, programming of the indication resolution, preview of all measuring values and set parameter values, rescaling of the input signal: multiplication and division by the constant counting of pulses, up and down automatic zeroing of counters at the required value, possibility of external zeroing, stoppage and start of counters, storage of all counter states in case in case of a decay of the supply voltage, automatic setting of the decimal point, programming digital filter of the input signal (for eliminating the contact vibrations storage of maximal and minimal values of all input quantities, programming of the time and kind of measurement averaging: arithmetic mean, walking window, display of the unit,service of the RS-485 interface in the MODBUS protocol, both in ASCII either in RTU mode, data protection by means of a password.
Input: programmable number of impulses, number of turns, worktime counter, frequency, rotational speed, period

Output: programmable - digital RS-485 MODBUS protocol, analog, 2 relays,
Display: LCD 2 x 8 signs,
Supply 253 V a.c./d.c. or 20...50 V a.c./d.c., available execution: with display and without display.

External dimensions: 45 x 120 x 100mm
