Built for large-format panel readout, this universal digital panel meter accepts thermocouple, RTD, thermistor, and analog current or voltage inputs. It shows values on a 4-digit 2.4" (60.96 mm) 7-segment LED display and runs on an AC supply. Best for wide-area readout where operators view the meter from a distance.

The Large Displays can handle a wide variety of signal inputs direct from transducer or process transmitters and offer multiple control output options and serial or Ethernet connectivity for logging the data.
The "Universal Temperature+Process Large Display" (iLD-UTP) is designed for Thermocouples, RTD's, and Process (DC) Voltage or Current. It handles TEN (10) thermocouple types: K, J, T, E, R, S, B, C, N, & J DIN.
It works with a wide selection of RTD's, both Pt. 0.00385 and 0.00392 curves for 100 Ohm, 500 Ohm, and 1000 Ohm and it measures with 2, 3, or 4 wire connections for the highest accuracy.
The Large Displays are easy to configure and scale to virtually any engineering units with the push buttons on the front panel, or with a personal computer using the free configuration software and the optional Ethernet connectivity or Serial Communications.
The Ethernet option allows the device to be connected on a standard Ethernet network and communicates using standard TCP/IP protocol. The Ethernet option (-C4EI) also includes RS485 (and RS422) Serial Communications.
The serial communications option (-C24) includes both RS232 and RS485 (and RS422) on one instrument. It communicates with a straightforward ASCII communications protocol, as well as MODBUS protocol.
The Universal Large Displays features a choice of two optional outputs: Form C SPDT (single pole double throw) mechanical relays (-3), Solid State Relays (-2), DC pulse (-4), and/or programmable analog output (-5) selectable as either a controlling function or as retransmission of the process value.
The Universal Large Displays can control simple manual operation to ON-OFF and full Autotune PID control. (Selectable preset tune, adaptive tune, PID, PI, PD control modes.) The dual control outputs can be configured for a variety of independent control and alarm applications.
The ramp-to-setpoint feature allows the user to define the rate of rise to setpoint, minimizing thermal shock to the load during start-up.
For applications that do not require PID control, Universal Large Displays controllers are available in a special model that offer simplified programming. The Universal Large Displays "Simplified Menu" model (specify -SM option) offers simplified programming. The menu flowchart is similar to programmable digital panel meters that are used for on/off control or alarms.
The Large Display can be programmed to change colors between RED, AMBER, and GREEN at any set point or alarm point. The Large Display has a wide range of signal inputs as well as control, alarm, and communication outputs including: RS232, RS485, MODBUS, and Ethernet.
The device with an embedded Web Server can connect directly to Ethernet/Internet. You can "see" your meter and control your process through a web browser over the Internet from halfway around the world. With the Large Display, you can also see your meter from a hundred feet.
The Large Display can be mounted flush in a panel or surface mounted with the included brackets. The entire Large Display enclosure provides NEMA 1 protection.
