Supported Applications
The DP25B-E and DP25B-S are 1/8 DIN panel meters from the DP25B platform, built for process and strain measurement and display. A large 4-digit, 9-segment display with patented programmable color lets the readout switch between red, amber and green at setpoints or alarm points, so operators can read status across a room at a glance.
The process (DP25B-E) build accepts DC voltage and current signals, while the strain (DP25B-S) build reads strain-gage bridges, with built-in bridge excitation. Optional relay outputs with adjustable deadband and isolated or non-isolated analog outputs let the meter both indicate and control, and the wider DP25B platform also supports thermocouple and 100 Ω Pt RTD inputs.
A NEMA 4 front bezel suits the meter to wash-down and dusty panel locations, and it carries CE, UKCA and UL US marks. Note: for inductive loads, a proper TVS protection diode should be fitted externally across the relay contacts to stay within the relay specifications.
Operating Conditions & Performance
The process and strain inputs cover a broad set of DC ranges - 0 to 100 mV, ±50 mV, 0 to 10 V, ±5 V, 0 to 20 mA and 4 to 20 mA - with an accuracy of 0.02% Rdg. The meter has a 15-bit resolution, a response time of 2 seconds, and programmable hysteresis from 0 to 9999.
For strain-gage bridges, firmware-selectable excitation is available at 24V @ 25 mA or 12V @ 50 mA, and at 10V @ 120 mA or 5V @ 60 mA, so the meter can drive a range of bridge configurations. Where the platform is used for temperature, thermocouple accuracy is ±0.5°C (0.9°F) and RTD (100 Ω Pt) covers -200 to 850°C (-328 to 1562°F).
The meter operates from 0 to 50°C (32 to 122°F) at up to 90% @ 40°C (104°F) non-condensing humidity and stores at -40 to 85°C (-40 to 185°F). Standard power is 115 Vac or 230 Vac ±10%, with low-voltage options of 10 to 32 Vdc and 26 to 56 Vdc. Outputs include 0 to 10 Vdc, 0 to 20 mA or 4 to 20 mA analog and dual 5 A SPDT (Form C) relays.
Configuration Options
The model number is assembled as DP25B - <Input Type> - <Power Option> - <Output Option>, so each meter's input, supply and output hardware are set at ordering. Within this series the input is fixed as process or strain, and capability differs by the power and output suffixes chosen.
Power options are:
- -230 - 230 Vac.
- -DC10/32 - 10 to 32 Vdc.
- -DC26/56 - 26 to 56 Vdc.
Output options are:
- -A - analog output.
- -AI-R - isolated analog output (the -R option is required with -AI).
- -R - dual 5 A relays.
- -AR - combined analog and relay options.
Key Product Differences
The two base input builds in this series are:
- DP25B-E - process meter for DC voltage and current.
- DP25B-S - strain-gage input meter.
Each is combined with a power suffix (standard 115 Vac, or the -230, -DC10/32 or -DC26/56 options) and an output suffix (-A, -R, -AR or -AI-R), which is how the 30 orderable configurations are built - for example a base DP25B-E, a mains DP25B-E-230-AR with analog and relays, or a low-voltage DP25B-E-DC10/32-R. The related DP25B-TC and DP25B-RTD models extend the same panel meter to thermocouple and RTD inputs.
The meter measures 48 H x 96 W x 152 mm D (1.89 x 3.78 x 6.0") and weighs 36 g (1.27 lb). The DPP-5 1/8 DIN panel punch is available as an accessory to prepare the mounting cutout.
