Between analog input terminal to FP0 internal circuit:
photocoupler insulation (non-insulated between analog inputs)
Between analog input terminal to analog I/O unit external power supply:
insulation-type DC/DC converter
Between analog input terminal to analog output terminal: insulation-type
DC/DC converter
Number of input contact points
ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ
32 input contact points:
16 points for 1st half: analog input CH0 data (WX2) (see note 6)
16 points for last half: analog input CH1 data (WX3) (see note 6)
Notes
1) A temperature lower than the terminal temperature of the
analog I/O unit cannot be measured.
2) A temperature higher than the terminal temperature of the
analog I/O unit cannot be measured.
3) The time noted below is required before the analog data is
reflected in the control unit input.
