OEM 1B Lascar

OEM 1B 3 Digit LCD Voltmeter Module PRODUCT DESCRIPTION The OEM 1B uses the latest miniaturisation techniques to produce a very compact 3 digit LCD voltmeter. It is designed to be a drop-in component in most medium and high volume applications, ranging from personal instrumentation and integral sensor indicators to measurement probes. The meter features 8mm digit height, 3 decimal points, auto-polarity, auto-zero, 200mV full scale reading and a very low current consumption. Connection to the module is via two dual in line rows of pins. FEATURES 8mm (0.31 ) Digit Height 200mV d.c. Full Scale Reading 150m A 7.5 to 14V Operation Auto-zero and Auto-polarity Selectable Decimal Points Very Compact Design TYPICAL APPLICATIONS ORDERING INFORMATION Personal Gas Monitoring Stock Number Medical Instruments Standard Meter OEM 1B Measurement Probes Hand held instruments ELECTRICAL SPECIFICATIONS Specification Min.

Supply current 150 m A Input leakage current (Vin = 0V) 1 10 pA * To ensure maximum accuracy, re-calibrate periodically. ** Operation of the meter beyond the maximum supply voltage rating may cause permanent damage to the meter. Unless otherwise noted, specifications apply at T =25C, V =5Vd.c. (f =48kHz) and are tested with the module configured for floating input A supply clock mode. SAFETY To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the modules pins must not exceed 60Vdc. The user must ensure that the incorporation of the panel meter into the users equipment conforms to the relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for Measuring, Control and Laboratory Use).
