Shown with optional backlight - loop powered The BA524G is a general purpose, loop powered 4/20mA field mounting indicator, with a large five digit display and a bargraph housed in a robust IP66 GRP or stainless steel enclosure. Main application of the BA524G is to display a measured variable in engineering units within a process area. The zero and span of the display are independently adjustable allowing the indicator to be calibrated to display any linear variable represented by the 4/20mA signal. A root extractor and an adjustable sixteen segment lineariser also enable the indicator to display flow and variables such as tank level in linear engineering units. For weighing applications a tare function is included. The large 29mm high 5 digit display and 31 segment bargraph provide maximum contrast and have a very wide viewing angle, allowing the BA524G indicator to be easily read in most lighting conditions over a wide temperature range. Optional factory fitted backlighting is available for installations in poorly illuminated areas. The five digit display, with four decimal points and a negative sign, may be configured to display any variable between -99999 and 99999. IP66 and impact protection are provided by a robust GRP or 316 stainless steel enclosure. Both have a thick armoured glass window and silicone gaskets. Impact and ingress protection have been assessed by UKAS accredited bodies. The BA524G and BA524G-SS are surface mounting, but can be pipe or panel mounted using accessories. Display backlighting which may be loop or separately powered is available as a factory fitted option. t provides green background illumination enabling the display to be read at night or in poorly illuminated areas. When powered from the 4/20mA loop, no additional wiring is required but the indicator's voltage drop is increased. Powering from a separate supply produces a slightly brighter backlight but requires additional field wiring. Optional dual alarm outputs which can switch low power loads, such as sounders, beacons or solenoid valves, are available as a factory fitted option. The two galvanically isolated solid state outputs may be independently conditioned as high or low alarms with normally open or closed outputs. Annunciators on the display show the status of both alarms. Reliability is ensured by protection from incorrect connection and radio frequency interference. The indicator has been subjected to extensive vibration and thermal testing and is supported by a three year guarantee. Other field mounting models in this range include the BA504G which has a similar specification with an even larger 4 digit, 34mm high display. If flammable atmospheres are present either the BA324G or BA304G, should be used. Both have the same features as the BA524G, but are intrinsically safe and have international certification for use in hazardous gas and dust atmospheres.
