Product Description

The readings of the 40B 48 millivolt input digital indicator are settable via the IP 65 face panel controls to adjust the relay trip points, decimal place, display update rate, resolution, engineering units and input linearisation.  Two buttons on the face panel can be configured for a choice of zero null, display hold, peak/valley storage and memory reset.

The 40B-48 millivolt input readout fits a 48mm x 48mm (1/16 DIN) panel cut-out and is supplied with an instrument mounting bracket.  Either a 100 to 240 Volts ac/dc or 11-27 Volts ac/dc input supply can be specified for powering the display.  There is also the option for specifying the sensor power supply for different types of sensor.
