Digital Panel Meters > 4 or 4 1/2 Digits

Otek Digital Panel Meters are available with LED or LCD displays. The displays come in a variety of formats including 3-3.5, 4-4.5, or 5-8 digits. Digital Panel Meters are available in plastic or metal housing and can be built to meet your most stringent environmental conditions or MIL-SPECs.  Multiple signal input as well as power input options provide a solution for virtually any application.

OTEK's Model  APM  is a four (4) digit green , red or blue LED indicator that accepts standard avionics power of 5-32VDC (Green, Red or Blue digits) and intensity control voltage of 1.5 - 5V 50-440Hz (or DC/Resistance). OTEK's exclusive powerless technique allows the APM to be loop powered causing a maximum of 5VDC burden to the loop.  The APM only requires 2 wires to operate.
 
The heart of the APM is an ASIC that accepts VDC or mADC and can be scaled (internally) to any value. The unit mounts in a standard avionics 1" diameter hole with four (4) mounting screws and connects to Power and signal via a "Twist Lock" circular connector (DBC53H-10-6P, Mating Cable End: MS347640 (L or M) -6S).
 
The APM is fully sealed and it is not affected by differential pressure, liquid spray (NEMA4X) or humidity (See Specs.).
 
APPLICABLE MIL-SPECS:
MIL-STD-461D, 462D, 704E, 130K, 810F, 889B2 & 1472F; MIL-HDBK-217F & 454A, RTCA-160F.

OTEK's SPM (3.78"W x 1.90"H x 2.70"D) is a signal or externally powered meter with an LED display.
 
With over 30 years in the Digital Panel Meter field, we had to bring you the best that technology would allow. The SPM is a combination of that expertise and newest technology in an industry's standard 1/8 DIN package. We started with a universal display (4 1/2 digit LED display) and embedded Sigma-Delta A/D. We added (Option 2) 3 1/2 LED .8" IF YOU DON’TSEE IT,ASK FOR IT!(Option 4) 4 LED .8" a "Bussed" mother board that we can add any of hundreds of designs from our 30+ years library to deliver the industry's only "Lifetime Warranted" Digital Panel Meter. Whether for Systems or just to monitor, control and/or communicate via Serial I/O. The modular construction of the SPM allows OTEK to customize to your needs without expensive N.R.E., set-ups or minimum orders.
 
Controller: When you order Serial I/O. (Digit 4 Options 1-3), you can order analog out (Digit 6) and/or relays (Digit 7) and we include math functions, X-Y tables & polynomials with it!
 
Displays: You can order the large 0.8" 3 1/2 or 4 digit LED or the 0.6" 4 1/2 LED. NEW white LED displays are now available!  Standard filter is red. For other colors use Option 9 on 8th digit and specify color (depending on availability).

The SRD (Serial Remote Display) brings information from a central computer network or SCADA system to a remote location with easy-to-read LCD or LED digits. In addition to being a remote digital indicator or slave display, the SRD can function as a programmable process controller, with both manual and reading-based operation. It is designed to work with any RS-232, RS-485, or USB network through an intuitive command set to display a message and control its relay and DAC outputs accordingly. In 1/8 DIN packaging, the SRD is easy to install and provides a simple solution to your industrial remote networking needs.
