5.2.6 PCD3.A400, 8 digital outputs for 0.5 A each
Application
Low cost output module with 8 transistor outputs 5...500 mA, without short-circuit
protection. For non-isolated current circuits in the voltage range 5...32 VDC.
Technical data
Number of outputs:
8, electrically connected
Output current:
5...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.
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...25 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
