Comment
Two sensors This setting is provided for dual probes or for two different probes.
Each of the two analog inputs is monitored separately for a probe break or
probe short-circuit.
Single Pt100 in 2-wire circuit V Caution:
When only one probe (SIL2) is connected, the temperature limiter device is
reduced from
SIL3 to SIL2.
However, the internal 2-channel structure (1oo2D) in the device still remains.
Both channels measure the same sensor due to the simplified external wiring.
Single 4 to 20 mA V Caution:
When only one probe (SIL2) is connected, the temperature limiter device is
reduced from
SIL3 to SIL2.
However, the internal 2-channel structure (1oo2D) in the device still remains.
Both channels measure the same current signal due to the simplified external
wiring.
