The BIG 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 BIG 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 Ω, 500 Ω, and 1000 Ω and it measures with 2, 3, or 4 wire connections for the highest accuracy. This model also measures process voltage: 0 to 100 mV, 0 to 1V, 0 to 10V ranges and process current, 0 to 20 mA (4 to 20 mA) with built-in excitation of 24 Vdc standard.
The “Universal Strain+Process BIG Display” (iLD-SP) handles a wide variety of DC voltage and current outputs from all common load cells, pressure transducers, and most any strain gage type of transducer. The meter measures input ranges of 0 to 100 mV, -100 mV to 1V, 0 to 10V, 0 to 20 mA (4 to 20 mA) with built-in excitation of 5 Vdc and 10 Vdc standard. This model also features 10 point linearization enabling accurate measurements from a wide assortment of unique and nonlinear transducers.

The BIG 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.
Control Functions
The Universal BIG 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 BIG 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. Maximum ramp time: 99.59 (HH.MM), Soak: 00.00 to 99.59 (HH.MM), Damping: 1 to 8 in unit steps. Input types: 0 to 20 mA, 0 to 100 mV, 0 to 1 V and 0 to 10 Vdc.
For applications that do not require PID control, Universal BIG Displays controllers are available in a special model that offer simplified programming. The Universal BIG 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. (Please see the Universal BIG Displays operator’s manuals for programming details.)

Programmable Color Display
The BIG Display can be programmed to change colors between RED,
AMBER, and GREEN at any set point
or alarm point. The BIG 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 BIG Display, you can also see your meter from a hundred feet.
The BIG Display can be mounted flush in a panel or surface mounted with the included brackets. The entire BIG Display enclosure provides NEMA 4 (IP65) protection. Whether panel-mounted or surface-mounted, the BIG Display does not need to go inside a bulky and expensive NEMA enclosure.
Configuration of the iLD-UTP or iLD-SP can be performed by using either -C24 or -C4EI options and the configuration software that is available on our website.
