;b>PR Electronics 4222 Universal I/f Converter ;/b>. PR Electronics 4222 Universal I/f Converter for linearizing electronic temperature measurement with RTD or thermocouple sensors. Also for the conversion of linear resistance variation to a standard analog current/voltage signal, i.e. from solenoids and butterfly valves or linear movements with attached potentiometer. ;b>Funkciók és előnyök ;/b>. Input for RTD, TC, Ohm, potentiometer, mA and Voltage Frequency output NPN, PNP and TTL Generates frequencies from 0.001 to 25000 Hz 2-wire supply > 16 V Universally powered by 21.6 to 253 Vac / 19.2 to 300 Vdc 3-port 2.3 kVAC galvanic isolation DIN-sínre szerelhető. ;b>Programming ;/b>. The 4222 universal converters are programmable via the PR 4501 detachable display module ( ; 7966890 7966890 ). The 4501 module allows the programming of the vast array of input and output parameters easily and safely. Together with advanced functions including 2-point calibration, process simulation and diagnostics. With a simple menu and explanatory text, the 4501 is extremely straightforward to navigate. Functions are clearly depicted on the 4-line LCD display even in low light conditions. Line 1 shows the input signal, line 2 shows the units, and line 3 shows analogue output or tag number. Line 4 shows the communication and relay status. In addition, the 4501 features password protection. Programming access can be blocked by assigning a password which is conveniently saved in the 4222 converter. This ensures a high degree of protection is maintained and prevents any unauthorised modifications to the configuration.
