FUNCTIONAL SPECIFICATIONS
Output “◊” For 4 to 20 mA HART / BRAIN (Output signal code D and J) Two wire 4 to 20 mA DC output with digital communications. BRAIN or HART FSK protocol are superimposed on the 4 to 20 mA signal. Output range: 3.6 mA to 21.6 mA Output limits conform to NAMUR NE43 can be preset by option code C2 or C3. For 1 to 5 V HART (Output signal code Q) Three or four wire low power 1 to 5 V DC output with HART, linear or square root programmable. HART protocol are superimposed on the 1 to 5 V DC signal. Output range: 0.9 V to 5.4 V DC Failure Alarm For 4 to 20 mA HART / BRAIN (Output signal code D and J) Output status at CPU failure and hardware error; Up-scale: 110%, 21.6 mA DC or more (standard) Down-scale: −5%, 3.2 mA DC or less For 1 to 5 V HART (Output signal code Q) Analog output status at CPU failure and hardware error; Up-scale: 110%, 5.4 V DC or more (standard) Down-scale: −5%, 0.8 V DC or less-
Damping Time Constant (1st order) Amplifier damping time constant is adjustable from 0.00 to 100.00 s by software and added to response time. Note: For BRAIN protocol type, when amplifier software damping is set to less than 0.5 s, communication may occasionally be unavailble during the operation, especially while output changes dynamically. The default setting of damping ensures stable communication. Update Period “◊” Pressure: 45 ms Zero Adjustment Limits Zero can be fully elevated or suppressed, within the lower and upper range limits of the capsule. External Zero Adjustment External zero is continuously adjustable with 0.01% incremental resolution of span. Re-range can be done locally using the digital indicator with rangesetting switch. Integral Indicator (LCD display, optional) “◊” 5-digit numerical display, 6-digit unit display and bar graph. The indicator is configurable to display one or up to three of the following variables periodically.; Pressure in %, scaled pressure, measured pressure. See also “Factory Setting.” Local Parameter Setting (Output signal code D, J and Q) Parameter configuration by the external zero adjustment screw and push button (Integral indicator code E) offers easy and quick setup for parameters of Loop test, Tag number, Unit, LRV, URV, Damping, Output mode (linear/square root), Display out 1, and Re-range by applying actual pressure (LRV/URV) and Device Informat 002
