The BLPM4NS is a 4 digits 9.5mm LED indicator designed for compactness providing an optimal ratio of digit size and front dimensions 48x24mm. The total depth is only 48mm which allows this indicator to be mounted into J-boxes or other small enclosures. The LED indicator is powered by the 4-20mA signal and provides adequate brightness in factory and control room locations but is not suitable for use in sunlight. The case is fully enclosed and has screw terminals suitable for fork connectors up to 7mm across. The indicator can be scaled on site using a pen to press the recessed buttons. The scaling buttons can be locked.
