RTD temperature probe Pt100 in
two-wire circuit, individual probe for both analog
inputs
Caution:
When only one probe (SIL2) is connected, the temperature limitation device
is reduced from SIL3 to SIL2. However, the internal 2-channel structure (1oo2D) in the device is still retained.
Both channels measure the same probe due to the simplified external circuit.
