Features
Smart Power
This signal conditioner uses Smart Power to control its output supply. Smart Power automatically adjusts the voltage to drive the output loop to the required current. A low impedance current loop will subsequently require less voltage than a loop with higher impedance. Previous designs provided only a single supply at the highest voltage required to drive the highest impedance load. Using Smart Power results in power savings and reduces the operating temperature of the signal conditioner.
Enhanced LED diagnostics
Other than when executing the pushbutton calibration routine, the LEDs blink under the following conditions:
An Under Range condition exists when the signal is lower than the operational low value minus 6.25% of the operational span. An Over Range condition exists when the signal is higher than the operational high value plus 6.25% of the operational span. A voltage output short circuit may cause an under range condition (RED blinking at 2 Hz rate). A current output open circuit may cause an over range condition (RED blinking at an 8 Hz rate). There could be two or more LEDs blinking at the same time, which means the module has more than one error condition. Only when all error conditions have been removed, will the LEDs be back to normal (Green ON, Red and Yellow Off).
