Microprocessor based indicator in both 48x48 (1/16 DIN) and 96x48 (1/8 DIN) formats manifactured with SMT. The instruments have a lexan membrane faceplate (guaranteed to IP65) which has 3 keys, a 3 digit display for the 48x48 format and a 3 / 4 digit display for the 96x48 format, and 3 indicating LED's for the output statuses. The input signal section provides for the visualisation of the sinusoidal effective value corresponding to following signals: AC voltage: 0 to 2, 0 to 20, 0 to 200 and 0 to 500Vac AC current: 0 to 20, 0 to 50, 0 to 200mAac 0 to 1, 0 to 5Aac The selection is made using the faceplate keys and correct input terminals. No external shunt or adapter is required. A digital input (24Vdc/4mA) is available for resetting, hold, flash, peak handling or releasing latch. The instruments have a maximum of 3 outputs that can be mechanical relays (5A/250V) or logic outputs (0 to 11Vdc). One output of 4 to 20mA (max. 150W) is available for retransmitting the measured input signal. The retransmission output, the digital input and the third output are alternatives in the 48x48 format, all these options are available contemporaneously in the 96x48 format. Finally, a triac can be fitted (as an alternative to the other two relay outputs) to drive resistive loads up to a maximum of 2,5A at 220V. The programming of the instrument is made easy by grouping the parameters in function blocks (CFG for the alarm hysteresis, Inp for the inputs, Out for the outputs...) and by a simplified data entry menu. The configuration can be simplified even further using the PC programming kit made up of a connection cable and a menu guide program that runs under Windows (see data sheet cod. 80021). A configurable personal software protection code (password protection) can be used to restrict the levels of editing and displaying the configuration parameters.
