Accurate and stable, this DC-powered DC voltage/current input isolating signal conditioner is a high-accuracy signal conditioner with an isolated DC voltage or current output. In addition, this conditioner features removable terminals for easy service.
Caractéristiques
Smart power
This signal conditioner uses Smart Power to control its output supply. Smart Power automatically adjusts the 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.
Approved for use in Class I Div 2 Group A, B, C, D areas
Users can now enjoy significant labor savings over traditional protection methods since there is no need for explosion proof enclosures and conduits. A Class I hazardous location is one in which flammable gases or vapors may be present in the air to be ignitable or explosive (typical applications include petroleum refineries, spray finishing areas, utility gas plants and fuel servicing areas). A Division 2 area is one in which the flammable gases or vapors are normally not present in an explosive concentration, but could accidentally exist. Group A is acetylene; Group B includes hydrogen; Group C includes ether; and Group D includes hydrocarbons, fuels and solvents.
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 2Hz 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).
