® EL-1-12BIT WINDOWS Compatible Data Logger EL-1-12BIT is an easy to use display module capable of measuring, recording, displaying and controlling temperature (Pt 100), voltage and current. With 12 bit A/D resolution, a memory for 8000 readings and a battery life of up to 3 years, EL-1-12BIT can operate as a 'stand alone' logger or be permanently connected to a system. The EL-1-12BIT serial link is addressable and up to 8 loggers can be connected to one serial port. The PC software operates under Windows and does not require specialist skill to operate. Data output is in text format and can be easily integrated into most popular spreadsheets. Graphical output is possible under EL-WIN. Consult the EasyLog software manual for further details. Battery Powered Multi-function °C Non-volatile Data Storage Panel Mounting Easy to Use High Resolution Read-out CONTROL SOFTWARE Stock Number - EL-WIN Easy to install and use, the control software will run under Windows 95 or 3.1 and enable the user to control one or more EasyLogs, operating them as a complete system. Supplied on a 3½" disk with a manual and serial link. Stock Number Data Logger Specification Range Temperature - Low Range * Stock Number - EasyLink Extension cable to 'daisy chain' more than one EasyLog. One extension will be needed for each extra EL-1-12BIT module that is attached to the chain. SENSOR SOURCING GUIDE Temperature - High Range * Current - D.C.

Input and output connections for Infra-Red communications, e.g.: connect to a PANEL-IR module. Switch input, normally pulled high. Connect momentarily to V- to take a reading in One-Shot Rear Pin Header mode or to start logging when configured for Push-to-Start in EL-WIN. Test pin. Do Not Use. External power supply connections. Read Important Note below prior to use. RxD TxD External supply voltage range 3 to 3.6Vdc. External power supply must be floating with AV+ SW respect to the signal to be measured. V+ VNormally at V-, these pins go high when their respective alarm levels have been reached LA HA or exceeded. VIN+ VINMeasurement Inputs, extension of screw terminal block connections. Iout RS Iin Current Loop connection, extension of screw terminal block connections. AV+: V-, V+: HA, LA VIN-, VIN+: Iin, Iout: IMPORTANT NOTE- Always remove the Lithium battery from the module BEFORE connecting an external power supply to the module. Failure to do so may cause the battery to explode. BATTERY REPLACEMENT Only use ½AA 3.6V lithium. The list below is not exhaustive. Check with supplier that the battery you are ordering is 'press fit' and is not fitted with solder tags. Take care to connect correctly. DO NOT PRESS ON LCD WHEN INSERTING BATTERY.

Dispose of in accordance with local regulations. APPLICATIONS NOTE -It is possible to measure parameters other than those outlined below. Use an appropriate sensor and conditioning circuit to convert the parameter to be measured into a linear voltage or current and apply this signal to a suitably scaled EL-1-12BIT module. Measurement signals must always be isolated from the communications signals.
