Low Cost, Ultra Compact
H-series Relay-Ladder Programmable Controllers
I. Introduction
The H-series is a family of small, low cost,
single-board Programmable Controllers. Presently, the series
spans 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 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 following
table summarizes the number of I/Os, timers, counters and internal relays for
each existing model:

Please note that For T22H, T28H, T40Hand T44H, an
enhanced CPU option is available which provides 256 internal relays, 40
timers, 40 counters and 800 steps. These PLCs are given respective model names
such as T20Hplus-npn, T28Hplus-Relay, T40Hplus-Relay, T44Hplus-pnp and
T44Hplus-npn.
