trodeks set the world standard for accuracy, performance and quality in digital panel meters. The all new DP41-B raises the bar even higher with accuracy of up to ±0.005% of reading, and up to 142 readings per second.
The versatile DP41-B handles a broad spectrum of dc voltage and current ranges, nine thermocouple types, multiple RTD's, and signals from strain gauge transducers such as load cells and pressure transducers, as well as potentiometric inputs. It also features ten point linearization of input signals, progammable by the user for custom applications.
Built-in excitation to power virtually any sensor or transmitter, and four isolated open collector outputs for control or alarms are standard. The big, bright, 6 digit patented LED display can be programmed to change color between Red, Amber, and Green at any set point. The digits are 58% bigger than the typical display. Output options include: Isolated programmable analog voltage or current and four relays.
With the Serial Communications option, the user can select from a push-button menu between RS232, RS485, and either a straightforward ASCII protocol or MODBUS. With trodeks’s award-winning Ethernet/Internet option, the new DP41-B connects directly to an Ethernet network and transmits data in standard TCP/IP protocol. It is possible to monitor and control a process through a web browser from anywhere on the Internet. | |
Embedded Internet and Serial Communications
Featuring optional "Embedded Internet" (specify EI option) the DP41-B connects directly to an Ethernet network and transmit data in standard TCP/IP packets, or even serve Web pages over a LAN or the Internet. The DP41-B is also available with serial communications. With the C24 option, the user can select from the push-button menu between RS232, RS422, and RS485, with straightforward ASCII commands or MODBUS.
Programmable Color Display
The DP41-B has totally programmable color displays. The display can be programmed to change color at any set point or alarm point.

 | | Change Color at any Setpoint
 | |
For example, the instrument can be programmed to display the process value in GREEN during warm-up, switching to AMBER to signal the normal operating range, and in RED to signal an alarm condition. The changes in color are quickly seen from a distance, and machine operators can intuitively react to changing conditions. The colors can be programmed to change back when the value drops back below the alarm point or to "latch" on until being reset by the operator.
The instrument can also be programmed to display only one unchanging color: GREEN, AMBER, or RED . This is a useful way to let an operator identify, at a glance, process values in three separate locations, or to display three different measurements such as Temperature, Pressure, and Flow. DP41-B LED displays are considerably bigger, brighter and therefore more visible than displays for conventional instruments with the same DIN size. | |
Quality and Technology
The innovative DP41-B meters feature an extended five (5) YEAR warranty at no extra charge. The DP41-B packs a wealth of power and features using COB (chip-on-board) and SMT (surface mount technology) assembly techniques and automation. Every DP41-B instrument is thoroughly calibrated and tested at several stages throughout production. The DP41-B offers the highest accuracy for industrial instrumentation at 0.005% of reading. The analog-to-digital conversion utilizes patented algorithms and smart filtering.

Universal Inputs
The innovative DP41-B offers the broadest selection of signal inputs available on one industrial instrument. The choices are easily selected from the menu with four front panel pushbuttons, or by serial or ethernet communications.
9 Thermocouple Types
The DP41-B handles NINE (9) thermocouple types: K, J, T, E, R, S, B, N, and J DIN. The patented thermocouple linearization algorithms employed in the DP41-B produce the highest standard of accuracy. | | | |
Most Accurate RTD Measurements
The DP41-B works with the widest selection of RTD's and produces the most accurate RTD measurements. Handles 100 ohm Pt both 0.00385 and 0.00392 curves. Any 6 to 6000 ohm NIST or DIN Pt and any linear RTD (10 ohm Cu, etc.). A choice of 2-, 3- and 4-wire RTD connections ensures the absolute highest degree of accuracy.
Process and Voltage Current
The trodeks® INF-B measures process voltage: 0-100 mV, 0-1 V, 0-10 V, 0-100 V (unipolar), ±50 mV, ±500 mV, ±5 V, ±50 V (bipolar) ranges, and process current: 0-20 mA or 4-20 mA.
Strain Gauge
The DP41-B measure inputs from Load Cells, Pressure Transducers, and most any strain gauge sensor. Input can be linearized over 10 pts on ranges. 0-100 mV, 0-1 V, 0-10 V, 0-100 V (unipolar), ±50 mV, ±500 mV, ±5 V, ±50 V (bipolar), in addition to 0-20mA. Excitation for transducers of 10 Volt and 24 Volt is standard. | |
Analog Output
The optional analog output can be programmed within a range of 0-10 Vdc or 0-20 mA. It is selectable as a calibrated retransmission of the process value.
Built-in Excitation Standard
The DP41-B comes standard with built-in excitation. You can capture and display both peak and valley levels of your input signals, an important feature for such applications as destructive and pressure testing. Five different kinds of excitation are available for sensors such as transmitters (24 Vdc @ 25 mA), strain gages (1.5 to 10 Vdc @ up to 60 mA max.), slide-wire potentiometers (1.25 Vdc @ 30 mA).

The DP41-B features plug/removable connectors and a sturdy panel mounting sleeve with adjustable thumb nuts for easy secure installation | |
The DP41-B displays feature unique 9-segment LED characters, which greatly improves alphanumeric representations. The 7-segment LED characters found on most instruments are adequate for presenting numbers, but not letters. Words are easier to read with the unique 9-segment LED characters on the DP41-B, which makes operating and programming simpler and easier.
