Dwyer Bulletin PC-SPPM Series Smart Programmable Panel Meters
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.

Wiring
Series SPPM features two voltage inputs that can be programmed independently.
With the downloadable software, the user can scale the two voltages to create
eight different voltage ranges. The software is programmed to use the smallest
range possible because the smallest voltage range offers the highest
resolution. The eight possible voltage ranges and their corresponding
resolutions can be found in the Table 1.
| Voltage Range (V) | Resolution (mV) |
|---|---|
| 0-1.25 | 0.3 |
| 0-2.5 | 0.6 |
| 0-4 | 1.0 |
| 0-5 | 1.2 |
| 0-8 | 2.0 |
| 0-10 | 2.4 |
| 0-20 | 4.9 |
| 0-40 | 9.8 |
- IN2 Analog voltage input 2 (maximum of 40 VDC)
- IN1 Analog voltage input 1 (maximum of 40 VDC)
- 0V 0 V power supply input
- V+ Positive power supply input (4-30 VDC)
Current Consumption
The current consumption of the panel meter is voltage dependent.
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
For safety reasons, the meter should be isolated from both the supply and
signal voltages before connecting the USB.
NOTICE
Launch the software before plugging in the smart panel meter.
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. 
for the pin layout.

MAINTENANCE
Upon final installation of Series SPPM, no routine maintenance is required. The display is not protected against moisture or dust and should only be cleaned with a dry, soft, and lint free cloth. Series SPPM is not field serviceable and should be returned if repair is needed (field repair should not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return goods authorization number before shipping.
