5.13.1 PCD2.W525 Combined analogue input/output modules with galvanic
isolation
General Information
PCD2.W525 is an analogue multipurpose module with four inputs and two outputs.
Each input and each output can be individually congured as one of the standard in-
dustrial interface type like 0 … 10 V, 0 … 20 mA and 4 … 20 mA. In addition, the inputs
can be congured to support Pt/Ni1000 or Pt500 temperature sensors. Furthermore,
the module offers high exibility in selecting lter types and scaling ranges.
Inputs-14 Bit
● 4 Inputs. Every channel has four modes of operation (congurable by DIP-
Switches):
○ Differential Voltage Inputs
0 … 10 V, resolution: 0.61 mV per LSB (14 Bit)
○ Differential Current Inputs-measured in differential mode
0 … 20 mA, resolution: 1.2 μA per LSB (14 Bit)
4 … 20 mA, resolution: 1.2 μA per LSB (13.7 Bit)
○ Temperature
Pt1000, -50 … 400 °C, resolution: 0.1 °C
Pt500, -50 … 400 °C, resolution: 0.2 °C
Ni1000, -60 … 200 °C, resolution 0.1 °C
○ Resistance
0 … 2500 Ω, resolution 0.2 Ω
● Each channel can be congured to have a software based 50 Hz / 60 Hz lter
Outputs-12 Bit
● 2 Outputs. Every channel has three modes of operation (congurable by soft-
ware):
○ Voltage
0 … 10 V, resolution: 2.44 mV per LSB (12 Bit)
○ Current
0 … 20 mA, resolution: 4.88 μA per LSB (12 Bit)
4 … 20 mA, resolution 4.88 μA per LSB (11.7 Bit)
○ High impedance
Miscellaneous
● All I/O-Channels are galvanically isolated to the Saia PCD
®
and external power
sup- ply. (But all channels are galvanically connected to each other.)
● Every channel has two connection terminals.
