The pCO can be connected to 2-wire PT1000 sensors for all high temperature applications; the operating range is: -100 to 200 °C.
The inputs must be configured for PT1000 signals by the application program resident in flash memory.
The connection diagram is shown below:
input: 24 V / ; 50 to 60 Hz
max. p ower:40 VA/15W

Warnings: Warnings:
•
to ensure a correct measurement by the PT1000 sensor, each sensor wire must be connected to a separate terminal, as shown in Figure 4.c;
•
the two PT1000 probe wires are equivalent, as there is no polarity, therefore no special order needs to be followed when connecting to the terminal block.

The pCO can be connected to all CAREL SPK* series active pressure probes or any pressure sensor available on the market with a 0 to 20 mA or 4 to 20 mA signal.
The inputs must be configured for 0 to 20 mA or 4 to 20 mA signals by the application program resident in flash memory.
