4-20 mA Output
The 4-20 mA output is a two wire circuit; it requires an external loop
supply of 12 to 30V DC to generate the isolated supply voltages needed.
The Tritex circuit requires 8V to operate; therefore the max impedance
the output can drive is dependent on the loop supply voltage. If the drive
is powered down, the output goes to an off-scale low output
approximately 2mA.
