4 Electrical connection 25 2014-05-01
4 to 20 mA
V
4 to 20 mA 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 current signal due to the simplified external circuit.
