Material no. R900021004 Differential input (input 2) 28(ac) 30(ac) u (i) u 0 … +10 V / 4 … 20 mA 0 … 20 mA 0 V reference potential The amendment of the connection designations in brackets only applies to type VT-VSPA1-1. The command value input 2 is a differential input [1] (0 to +10 V). By means of DIL switches 2), it can be configured as current input (+4 to +20 mA or 0 to +20 mA). If the command value is specified by external electronics with a different reference potential (e.g. by a PLC), this input has to be used. When disconnecting or connecting the command value voltage, it has to be ensured that both signal lines are in each case separated from or connected with the input. Before they are forwarded, both command values are summed up [2] and then reach a potentiometer [3] accessible at the front plate of the card which acts as attenuator and thus limits the maximum command value.
