This low cost, compact indicator is ideally suited for low or high volume applications. SP 5-1200-BL is an easy to
mount LCD digital panel meter. The module features a 4 to 25V measurement range with 100mV resolution and
is powered from the signal it is measuring. Only valid readings are displayed; the module indicates "LO" at
voltages below 4V and "HI" at voltages above 25V. Screw terminals allow for quick and easy connection. The
module is panel mounted using the metal clip provided and a rubber seal is included, providing splashproof
protection for the unit when fitted to the meter during installation.

2-Wire Signal-Powered Meter
* At voltages below 4.0V d.c., the LCD will display and will ultimately go blank.
At Voltages in excess of 25.0V d.c., the LCD will display .
Do NOT exceed 50V d.c., as this may damage the meter.
The module includes reverse polarity protection up to 30V for up to 30 seconds.
Operation and accuracy at voltages above 25.0V or below 4.0V are not specified.

SAFETY
To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s connections must not
exceed 60Vd.c. The user must ensure that the incorporation of the 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).
