The simulator is essential and indispensablefor operation and understanding of the analogue modules of the PLC. The boardincludes 2+2 inputs, at 4-20 mA and 0-10 V respectively, and 4 outputs at 4-20mA/0/1-5 V, smoothly variable through potentiometer; the current/ voltagedisplay is of digital type; the input indication is of bar type, through metersthat can be switched. Moreover, 4 outputs at 24 Vdc/1 A are available,internally powered. The connection to the PLC can be carried out throughterminals or connector. Power supply: single-phase from mains.
