Migrating an auxiliary input wired to a
sourcing field device that relies on
series/parallel resistors
Matrox 4Sight EV6 supports interfacing with sourcing field devices without the
use of external resistors, assuming external resistors are not required for the proper
operation of the sourcing field device. In this case, you can simply remove the
external resistors and wire the sourcing field device directly to the
Matrox 4Sight EV6 input. Wiring a sourcing field device directly to a
Matrox 4Sight EV6 input will operate reliably as long as the sourcing field device
can supply 2.25 mA of current when it is in a closed state (that is, 11 V are detected
across the Matrox 4Sight EV6 and AUX_INn- pins).
