BA567E-SS Rugged one input counter General purpose Proximity detector, magnetic pick-off, voltage pulse, switch contact or open collector sensor u 05 x 60mm rugged 1 316 stainless steel enclosure with IP66 front protection. Shown with optional backlight The BA567E-SS is a one input general purpose counter housed in a 316 stainless steel enclosure with a 10mm thick toughened glass window. The instrument has IP66 front of panel protection and is suitable for use in hostile and marine environments, or where the front of the instrument is likely to be impacted. The counter is easy to use and can be configured on-site to operate with a magnetic pick-off, switch contact, proximity detector, open collector or a voltage pulse sensor. A slide-in scale card shows the units of measurement. Main application of the BA567E-SS is to count the number of pulses received from a process area sensor such as a 2-wire proximity detector and simultaneously display the rate and total number in engineering units within the process area. The display has high contrast and a wide viewing angle enabling the counter to be read in most lighting conditions over a wide temperature range. The total number of pulses may be scaled and displayed in almost any units to represent the engineering variable being counted. The total display may be reset using the front panel push buttons or an external contact closure. The pulse rate may be shown in the same or different units per second, minute or hour. Display backlighting which is internally powered from the counter is available as a factory fitted option. It provides green background illumination enhancing daylight viewing and allowing the display to be easily read at night or when installed in a poorly illuminated area. One of the following three isolated outputs may be fitted to a BA567E-SS counter. All are factory fitted options. Optional open collector pulse output will synchronously retransmit the counter input pulse, or a pulse when the least significant digit of the total display is incremented. magnetic pick-off, switch contact, proximity detector, open collector or voltage pulse. u Separate rate and total displays. Optional 4/20mA current sink output may be configured to produce an analogue output proportional to any part of the total or rate display, Optional dual alarms can switch loads such as a sounder or solenoid valve. The two galvanically isolated, solid state, voltage free outputs may be independently conditioned as rate or total alarms with normally open or closed outputs. Annunciators on the BA567E-SS display show the status of both alarm outputs. Backlight dual alarms or 4/20mA output or pulse output For less hostile environments the BA567E is identical to the BA567E-SS except that it is housed in a Noryl enclosure also providing IP66 front of panel protection. Simple on-site scale card installation. The BA568E is a two input counter with a larger display in a 144 x 72mm DIN enclosure. Both inputs can be displayed separately and, depending upon the configuration, their sum or difference can also be shown. For applications in flammable atmospheres the BA367E-SS, which is identical to the BA567E-SS, has international intrinsic safety certification. The BA367NE has Ex nA and Ex tc approval allowing use in Zone 2 or 22 without Zener barriers or galvanic isolators. BEKA associates Ltd. Old Charlton Rd. Hitchin, Hertfordshire, SG5 2DA, U.K. Tel.
