AutomationDirect DPM2 User Manual
Digital Panel Meters - DPM2
Series 1/8 DIN
The ProSense DPM2 series offers a simple,
low cost digital display of analog process
signals, temperature in either Fahrenheit
or Celsius from RTD or thermocouple
temperature sensors, or potentiometer

Features:
• 96 x 48mm 1/8 DIN
• Simple menu driven pushbutton configuration
• 14mm 4-digit (-9999 to 9999) or 20mm (-1999 to 9999)
red LED display
• Selectable decimal point
• Process input (±10V, ±200V and ±20mA)
• Temperature input (RTD: Pt100, Pt1000, TC: J, K, T, N,
Resolution: 1°F, 0.1°F, 1°C, 0.1°C)
• Potentiometer input (100Ω to 100kΩ)
• Resistance input (999.9Ω, 9999Ω and 50kΩ)
inputs. The 4-digit 14mm character height
red LED display is easily scaled into any
engineering units from -9999 to 9999
with a selectable decimal point location.
The DPM2L offers a larger 20mm character height scaled from -1999 to 9999.
Two point direct or reverse acting linear
scaling values can be entered manually
or by introducing actual sensed process
values in Teach mode. Temperature inputs
are pre-configured for fixed temperature
ranges based on the type of temperature
sensor and can be displayed with 1 or 0.1
degree of resolution. One model includes

two SPDT relay outputs that can be set to
activate on an increasing or decreasing
input signal with hysteresis or time delay
operation. The meter is powered from
an external wide range AC or DC power
supply and provides 24VDC for external
sensor excitation. The 1/8 DIN housing
is easy to install in a panel and the meter
face has an IP65 rating. Configuration
parameters can be totally or selectively
locked out to prevent unauthorized or
accidental changes to the meter’s operation. Additionally, the DPM2 meters
include memory and reset of minimum
and maximum display values. ProSense
digital panel meters are backed by a 3
year warranty.
