5 V supply for 5 V encoder modules PCD2.H325 and PCD2.H327
Short circuit protection Yes
Electrical isolation No
Output voltage 5 V
Max. load current 300 mA
Short circuit current 400 mA
Overvoltage protection TVS diode 39 V +/- 10 %
Reverse voltage protection No
Power supply to all modules
Internal current consumption:
from +5 V bus (without en-
coder)
typically 210 mA, max. 230 mA
(250 mA in SSI operation)
Internal current consumption:
from V+ bus (without encoder)
15 … 20 mA
External current consumption: 0 … 2 mA (without load current)
1 A for outputs
Total current consumption for all I/O modules including encoders must not exceed 1.6 A.
PCD2.H32x modules should be plugged onto the base unit wherever possible (not the ex-
pansion housing).
Operational conditions
Ambient temperature operation: 0 … +55 °C without forced ventilation,
storage: -20 … +85 °C
Noise immunity: EC mark according to EN 61 000-6-3 and EN 61 000-6-2
Programming: Based on Saia PCD
®
user program and pre-programmed
function blocks (FB).
Terminals: Pluggable 10-pole spring terminal block
(4 405 4847 0), for wires up to 1.5 mm²
