Input/output (I/O) modules
5-128
Motion control modules for servo-motors
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)
