Analogue output modules with electrically isolation
5.11.1 PCD2.W6x5, analogue outputs, 6 (4) channels, 10 bit resolution, el. isol.
Application
High-speed output module with galvanic separation of outputs to Saia PCD
®
bus,
for general use with 6 (4) channels, each with 10 bit resolution. Different variants for
voltage 0 … 10 V, -10 V … +10 V and current 0 … 20 mA are available.

PCD2.W605: Voltage 0 … 10 V 6 (A0 … A5) 10 mV
PCD2.W615: Current 0 … 20 mA 4 (A0 … A3) 20 μA
PCD2.W625: Voltage -10 … +10 V 6 (A0 … A5) 20 mV
Technical data
Output ranges: see module overview
Galvanic separation: 500 V, galvanic separation of outputs to Saia PCD
®
,
channels themselves not separated
Resolution (digital representation): 10 bits (0 … 1023)
Loadresistance: W605: >3 kΩ

Accuracy at 25 °C W605: ± 0.4 %
W615: ± 0.7 %
W625: ± 0.4 %
Temperature error (0 … +55 °C) ± 0.25 %, 100 ppm/K or 0.01 %/K
Short circuitprotection: yes (permanent)
EMC protection: acc. to standards ENV 50141, EN 55022,
EN 61 000-4-2, EN 61 000-4-4, EN 61 000-4-5
Time constant of output lter: W605: typically 1 ms
W615: typically 0.3 ms
W625: typically 1 ms
Internal current consumption:
(from +5 V bus)
W605: 110 mA (typ. 80 mA)
W615: 55 mA (typically 45 mA)
W625: 110 mA (typically 80 mA)
Internal current consumption:
(from V+ bus)
W605/W625: 0 mA
W615: 90 mA

Voltage range: RL•20 mA + 10 … 20 V
*E.g. RL=500 Ω → Ue = 20 … 30 V
RL=0 Ω → Ue=10 … 20 V
Terminals: Pluggable 14-pole spring terminal block
(4 405 4998 0), for wires up to 1.5 mm²
