The Model 267 and 267MR is a two-wire loop-powered 4 to 20mA current output unit (see Diagram
5). The current flows into +EXC. terminal and returns back to the power supply through the -EXC.
Terminal (see Diagram 6). The power supply must be a DC voltage source with a voltage range
between 9 and 30 measured between teEXC. and -EXC. The unit is calibrated with a 24 VDC
loop supply voltage and a 250 ohm load.
