The Analog Output module has four output channels that may be either 4-20 ma or 1-5 Vdc. The digital-to-analog converter on the module supports 12 bit data; this provides 1600 steps in the active output range with an accuracy of ±0.1%. The output current loop requires connection to an external voltage source. When the internal MOSCAD power supply/battery is utilized, the module will drive a load of up to 250 ohms but when an external 24Vdc power source is provided, the module will drive a load up to 750 ohms. The current drain on this power source will continue during ac mains failure unless handled specifically by the application; the backup battery life will be shortened if it is used as the loop power source. All wire connections to the module are via plug-in screw terminals. Availability: Usually ships in 6-8 weeks.
