T28H-Relay (End-Of-Life)
Description
Designed specifically for power control purposes, the T28H-Relay is the only programmable logic controller that offers 12 high current (10A @ 250V AC), individually isolated relay outputs. The 2500VA contact rating for every output makes T28H-Relay the only true power controller in the industry.

Each T28H-Relay controller comprises 16 inputs, 12 outputs, 128 internal relays, 20 timers, 20 counters and 8 sequencers. In addition to basic high-speed AND/OR/OUT instructions, T28H supports a number of useful special functions such as sequencers, reversible up/down counters, differentiated instructions and latch relays to handle the most demanding applications.

The H-series PLC is a family of small, low cost, single-board Programmable Logic Controllers (PLCs). Presently, the series spans from the T20H with 12 inputs, 8 outputs to the T64H with 40 inputs and 24 outputs. Members of the H-series controller family differ mainly in the number of I/Os (inputs/outputs), and the type of I/Os they carry (relay or transistor outputs, PNP or NPN types, opto-isolator inputs or high voltage inputs, etc). Since each different PLC model has different wiring requirements, please refer to their respective Installation Guide on the wiring methods and installation details. The number of I/Os, timers, counters, internal relays as well as the maximum allowable program steps are also stated in the Installation Guide.

The H-series controller is programmed using the software Win-TRiLOGI which runs on an Windows compatible PC. This is a full-screen ladder logic editor, compiler and simulator software. Win-TRiLOGI is a standalone software package which provides a powerful programming and debugging environment for ladder logic programming. Please refer to Win-TRiLOGI's product page for details.
