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 configured as one of the stand
-
ard industrial interface type like 0 … 10 V, 0 … 20 mA and 4 … 20 mA. In addition,
the inputs can be configured to support Pt/Ni1000 or Pt500 temperature sensors.
Furthermore, the module offers high flexibility in selecting filter types and scaling
ranges.
Inputs-14 Bit
● 4 Inputs. Every channel has four modes of operation (configurable 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 configured to have a software based 50 Hz / 60 Hz filter
Outputs-12 Bit
● 2 Outputs. Every channel has three modes of operation (configurable 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
supply. (But all channels are galvanically connected to each other.)
●
Every channel has two connection terminals.
