SPPM-35

The Series SPPM Smart Programmable Panel Meter is a configurable, full color

display that can be used in a variety of applications. Utilizing a USB connection,
the panel meter can be configured with downloadable software, using any
computer running Windows

®

based software. Available with a 2.4˝, 2.8˝ or 3.5˝
screen which features remarkable graphics that can easily be customized to read
and/or graph pressure, temperature, humidity, gas concentration, or many other
parameters. Up to two transmitters or transducers can feed the panel meter’s user
scalable inputs. The Series SPPM includes a gasket and mounting clip for quick
installation into a panel.

USB Connection

A USB cable is required for customization of the Series SPPM. When connected to a
PC’s USB port, the display is powered by the PC.

CAUTION

NOTICE

Pin Connection

The DIL IDC socket is an alternative to using the screw terminals. This connection can
also be utilized for data busses and alarm outputs. See Figure 3 for the pin layout.

For safety reasons, the meter should be isolated from both the
supply and signal voltages before connecting the USB.

Launch the software before plugging in the smart panel meter.
