Low Cost, Ultra Compact
H-series Relay Ladder Programmable Controllers

The Muscular Power Controller: T28H-Relay

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.
