5.2.7 PCD3.A410, 8 digital outputs for 0.5 A each, galvanically isolated
Application
Output
module, galvanically isolated from the CPU, with 8 MOSFET transistors
outputs 1...500 mA, without short-circuit protection.
Technical data
Number of outputs:
8,
galvanically
isolated
Output current:
1...500 mA (leakage current max. 0,1 mA)
Within the voltage range 5... 24 VDC the load resistance
should be at least 48Ω.
Total current per module:
4 A on 100% duty cycle
Operating mode:
Source operation (positive switching)
Voltage range:
5...32 VDC, smoothed
10...25 VDC, pulsed
Voltage drop:
≤ 0,4V at 0,5 A
Typical output delay:
10 μs switch on delay
50 μs switch off delay
(ohmic load 5...500 mA),
longer with inductive load, due to the protective diode.
Electrical isolation voltage
1000 VAC, 1 min. (All terminal connections against CPU
part)
Resistance to interference:
according to IEC 801-4
4 kV under direct coupling
2 kV under capacitive coupling (whole trunk group)
Internal current consumption:
(from +5 V bus)
1...24 mA
typ. 15 mA
Internal current consumption:
(from V+ bus)
0 mA
External current consumption: load current
Terminal:
Pluggable 10-pole cage clamp terminal (4 405 4957 0) or
pluggable 10-pole screw terminal (4 405 4959 0), both for
wires up to 2.5 mm²
