DP41-E 1/8 DIN High Performance Temp, Process & Strain Meter

 Supported Applications

The DP41 Series is a 1/8 DIN high-performance digital panel meter and controller for industrial instrumentation, with a high-resolution 6-digit display. A single platform reads a remarkably wide set of inputs - DC voltage and current, thermocouples (9 types), 2-, 3- or 4-wire RTDs, strain gages, load cells and potentiometers - so one meter family can be standardized across temperature, process, force and weight applications.

A 14-segment LED display gives clear alphanumeric messaging, and built-in alarm and control capability lets the meter act on a measurement, not just display it. Isolated RS232/RS485 communications, analog retransmission, BCD output and relay outputs are available as plug-in boards for integration and control.

The front panel is rated NEMA 4 (IP65) for wash-down and dusty environments, and the meter carries CE, UKCA and cULus marks. A red LED display is standard, with a green LED available at no charge.

Operating Conditions & Performance

The meter offers a headline accuracy of ±0.005% rdg with a 15-bit resolution and dual-slope conversion. Step response is 1 s to 99.9%, the reading rate is 3 or 13 readings per second at 60 Hz (3 or 12 at 50 Hz), and rated accuracy is reached after a 50-minute warm-up. Thermocouple and RTD resolution is 0.01°.

Thermocouple input ranges and accuracies are:

• Type J: -210 to 760°C (-346 to 1400°F), to 0.2°C (0.3°F).
• Type K: -270 to 1372°C (-454 to 2500°F), to 0.2°C (0.3°F).
• Type T: -270 to 400°C (-454 to 752°F).
• Type E: -270 to 1000°C (-454 to 1832°F).
• Type R/S: -50 to 1768°C (-58 to 3214°F).
• Type B: 100 to 1820°C (212 to 3300°F).
• Type N: -270 to 1300°C (-454 to 2372°F).
• J DIN: -200 to 900°C (-328 to 1652°F), to 0.6°C (1.0°F).
• RTD: -200 to 850°C (-328 to 1562°F), to 0.2°C (0.3°F).

DC ranges cover 0 to 100 mV, ±500 mV, 0 to 5 V, 1 to 5 V, 0 to 10 V, 0 to 100 V, ±5 V, ±50 V, 0 to 20 mA and 4 to 20 mA, and bridge excitation is available at 10 V at 30 mA or 24 V at 25 mA.

The meter operates from 0 to 50°C (32 to 122°F) at 95% RH non-condensing and stores at -40 to 85°C (-40 to 185°F). Power is 115 or 230 Vac, 49 to 400 Hz, or 10 to 32 Vdc. Analog output spans 0 to 5 V, 0 to 10 V, 0 to 20 mA and 4 to 20 mA, with dual 7 A mechanical relays available as a board option.

Configuration Options

The model number is assembled as DP41 - <Input Type> - <Power> - <Communications> - <Output> - <Accessory>, so the meter is configured input-first and then built up with power, communication and output options. Power and display options include:

• -230 - 230 Vac power.
• -DC - 10 to 32 Vdc isolated power.
• -GN - green LED display.

Output and communication capability is added through plug-in boards, which map to the suffixes in the model number:

• DP40-A3 - analog output.
• DP40-S24 - isolated RS232/485 communications.
• DP40-B - isolated BCD output board.
• DP40-R - dual 7 A mechanical relays; DP40-R4 - dual 7 A and dual 1 A relays.

Because inputs, power, communications and outputs are ordered independently, a base DP41-TC becomes a fully featured DP41-TC-230-S2A with mains power, communications and analog output, or a low-voltage DP41-E-DC-AR4 with analog output and relays.

Key Product Differences

The platform is organized first by input type. The core To Order indicators are:

• DP41-E - process voltage/current indicator.
• DP41-TC - thermocouple indicator.
• DP41-RTD - RTD indicator.
• DP41-U - universal input indicator.
• DP41-S - strain gage indicator; DP41-W - NTEP weight strain indicator.

Each is also offered as a DP41Z split-display version (DP41Z-E, DP41Z-TC, DP41Z-RTD, DP41Z-U, DP41Z-S and DP41Z-W) with a remote display. Every input model then combines with power, communication and output suffixes to form the full lineup - for example DP41-U-230-S2, DP41-RTD-DC-S4 or DP41-E-S2AR4.

Accessories include the SPC4 and SPC18 NEMA 4 (IP65) splashproof lenses, 9- and 25-pin serial connectors (DP40-9SC2, DP40-9SC4, DP40-25SC2, DP40-25SC4), the DP41-TBS bench stand and the DPP-5 1/8 DIN panel punch. The meter measures 48 H x 96 W x 165 mm D (1.89 x 3.78 x 6.5") and weighs 574 g (1.27 lb).
