Connecting sensors to the IOC8T
CONFIGURATION OF AMC8 / IOC8T CARDS
10.2.4 Connecting other sensors (process values)
The AMC8 / IOC8T card pair can process signals coming from a variety of other devices such
as flow rate detectors, fluid level detectors and so on. The pair can process current-based
and voltage-based signals.
10.2.4.1 Current-based signal
Devices that output a current-based signal (4 to 20 mA) should be connected to the IOC8T
as shown in Figure 10-8.
