PCD2.H32x

Input/output (I/O) modules

5

Digital inputs for all PCD2.H32x modules per axis

Number of inputs 1 reference input “REF” 1)

2 limit switch inputs “LS1 / LS2” 1)

1 synchronization input “SI” 2)

Input voltage 24 VDC (6 to 32 VDC) smoothed,

max. residual ripple 10 %

“Low” range -30 ... +5 V

“High” range +15 ... +32 V

Input current at 24 VDC 7 mA (typically)

Circuit type electrically connected

Reaction time 300 μs

1) For safety reasons, normally-closed (NC) or PNP sensors should be used for the

reference and limit switches. For this reason, these inputs work in sink mode

(negative logic, i.e. LED = on when 0 V at input).

2) The synchronization input works in source mode (positive logic)
