Triangle Research International (TRi) specializes in manufacturing programmable logic controllers (PLCs) that are designed for embedding into OEM applications. Our family of no frills, PCB style Ethernet-equipped Super PLCs provide a complete array of high-value solutions for any OEM manufacturer's needs.

More importantly, our highly acclaimed i-TRiLOGI^TM Ladder+BASIC software reduces programming of complex control tasks on these Super PLCs into a few simple keywords. i-TRiLOGI's ease of use, coupled with its built-in simulator makes it a software of choice for many educational institutes - To-date more than half a million copies of the educational version of this popular software have been downloaded by enthusiastic users!

The Traditional Ladder Logic, Embedded PLCs - Available since 1993

Digital I/Os only - No Analog
Pure Ladder Logic only (no TBASIC)
No LCD display. Does not work with Serial HMI
Does not support MODBUS protocols
Low cost. Extremely stable. Continued to be used by OEMs for simple applications.

E10+ Series

Tiny Ladder PLC

H-series

First PLC since 1993

With 4 DI, 4 DO and 2 AI, this tiny PLC combines absolutely unbelievable capability (Ethernet, stepper, high speed counters etc) and cool AJAX Internet technology. Users can easily create their own web page from which they can control their equipment without writing a single line of Internet program. MUST see to believe!

Fully support industry-standard MODBUS TCP/IP and MODBUS RTU protocols
Easily connect to any SCADA software host or LCD touch panel HMI
Readily integrate into any plant-wide automation or control network
Program using our highly acclaimed LADDER+BASIC programming language

a. close relationship with automation OEMs
b. optimum configurations to
- minimize unnecessary features (open-case design suitable for most OEM applications which have require system panel)
- minimize total user cost with features integrated into PLC
- minimize no.of models and therefore, cost of production
- minimize support cost with less models to focus on
c. deep-sourcing of reliable parts to meet stringent price targets
d.direct sales infrastructure means less middle tier cost-add to OEM customer
