What is the maximum voltage per channel for the analog output module BMXAMO0802?

Issue: What is the maximum voltage per channel for the analog output module BMXAMO0802?

Product Line:  Modicon PAC / X80 / BMXAMO0802 / BMXAMO0802H

Resolution: Referring to the Modicon X80 Analog Input/Output Modules User Manual, the output current information is as follows:


From the above chart,  the nominal variation range of current and the load impedance of each output channel can be determined, therefore, with this information, the voltage can be calculated given the current and impedance on a DC current loop as shown below:

V=IR

V : DC Voltage in Volts V
I : DC Current in Amps A
R : Impedance in Ohms Ω

V=0.020 A ×350 Ω
V=7 V

In conclusion, the max voltage per output channel is 7 volts; consider that if the device exceeds 350 Ohms, the module may not work as intended.
