ET2010/- Features www.oxleygroup.com Electronic Elapsed Time Indicator and Event Counter ET2010/This chapter contains product information for the Electronic Elapsed Time Indicator and Event Counter ET2010/-. Features • Total electronic circuitry. • Hours and/or events in a single package. • EEPROM non-volatile memory. • 10 years data retention. • Printed circuit board mounting. • Remote interrogation with hand-held reader. • Nuclear survivability. For ordering information see page 16. Description The Oxley Electronic Elapsed Time Indicator Type ET2010 is a PCB mounting device designed to record both elapsed time and events. It is encapsulated in a low profile, board mounting package and ideal for incorporation into equipment where individual Printed Circuit Board monitoring is required. The small package size is highly suitable for systems where space is at a premium. The ET2010 is available in 8 different versions, offering varying combinations of resolution and capacity. It is equipped with a synchronous output data signal which may be simply interfaced to an LCD display; alternatively the Oxley ET/HHR/3A hand-held reader may be used. For details of LCD driver circuitry, please contact the Technical Sales Department. 4.57 1.5 7.62 mm 6 mm Ø1 2.54 2.54 27.4 mm Ø 0.7 13.4 mm 22.86 mm (0.9") Pin 1 Oxley UK, Email [email protected] Tel: +44 (0) 1229 582621 Fax: +44 (0) 1229 585090 13 Oxley Inc.

This pin is compatible with supplies as defined by DEF STAN 61-5 Part 6 (Pin 1). CLK Asynchronous clock pin for use with LCD display driver or Oxley ET/HHR/3A hand-held reader (Pin 2). EVEN TTL compatible input for use when TTL event counting EETI’s are used. This pin is internally pulled T down to 0 V using a 100 KΩ resistor and may be left unconnected when not required (Pin 8). LCD Asynchronous data pin for use with LCD display driver or Oxley ET/HHR/3A hand-held reader (Pin 9). 0V Power supply common. Used in conjunction with either +28 V or Vcc (+5 V) (Pin 10). Vcc Positive supply (4.5 V d.c. to 10 V d.c.). Supplies exceeding this limit may be connected by inserting a (+5 V) series resistor (Pin 11). LOAD Asynchronous data load pin for connection to LCD display driver or Oxley ET/ HHR/3A (Pin 12). N.C No connection (Pin 19). Vaux Positive supply connection for cold reads. Providing no supply is present at either +28 V or Vcc (+5 V) powering the device by this pin will inhibit all counting or timing functions. The voltage at this pin must be within the range 4.8 V d.c. to 6 V d.c. (Pin 20).

The reader is battery powered, capable of interrogating the device without incrementing the data stored within, and has no requirement for the host equipment to be energised. When active, the reader automatically recognises the type of EETI connected and correctly formats the information.
