Preferred current direction because of internal diode
Designed for the connection of externally-supplied
sensors with a 3/4-wire connection
Designed for the connection of self-supplied sensors
with a 2-wire connection
EL3692
Differential
EL3x1x: 0-20 mA, EL3x2x: 4-20 mA; KL exactly the
same
Preferred current direction because of internal diode
The terminal is a passive differential current
measuring device; passive means that the sensor is
