ELECTRICAL SPECIFICATIONS

*** This specification linearly derates to 30mA @ 50°C.

SAFETY

To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pins must not exceed

60Vdc. The user must ensure that the incorporation of the panel meter into the user’s equipment conforms to the

relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for Measuring, Control and

Laboratory Use).
