H-series

The H-series PLCs are a family of small, low cost, pure relay-ladder logic (i.e. not complemented with BASIC programming) based PLCs that are available since 1993. This PLC family is known for it's proven track record and ranges from the T22H with 12 inputs, 10 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.

 

As of 1/1/2012, the H-series PLCs effectively includes only the T28H-Relay and T40H-Relay models. Per the status below, the T22H-npn, T44H-pnp, T44H-npn and the T64H-Relay have been reclassified as Legacy Products and are available only to past customers under special circumstances. The following table summarizes the number of I/Os, timers, counters and internal relays for each existing model :

"Your PLC I purchased for our prototype system did exactly as you said. The instructions were clear and your on line help was very good. I will continue trading with you in the future. We have no plans to look for alternative PLCs other than your products". -  Click here to read what other users say about our PLC products and services
