PR Electronics 4222 Universal I/f Converter

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.

Features and Benefits

• 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 Rail mounting

Programming

The 4222 universal converters are programmable via the PR 4501 detachable display module (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.
