PR Electronics 5223 Series Programmable Signal Conditioner, Relay Output, 21.6 V ac, 253 V ac, 19.2V dc, 300 V dc Supply

5223A is a programmable f/I - ff converter. The f/I function performs frequency to current and voltage conversion, the f/f function can be used for pulse division or multiplication and as a buffer collecting fast pulse trains.
The 5223A transmitter can be configured with a standard PC and the Loop Link communications unit, or delivered fully configured.

The 9203B universal transmitters are programmable via the PR 4501 detachable display module (238-0641). 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 9203B transmitter. This ensures a high degree of protection is maintained and prevents any unauthorised modifications to the configuration.
