Hima
The HIMA PES
The HIMA PES mainly consists of the H41q and H51q system families. Both system families are based on the same
hardware and software, and they are the 3rd generation of the field-proven HIMA PES to control prefe-rably process
engineering plants. Additionally personal computers are used for configuration, logging, operation, and trend
recording.
Digital and analog inputs can be processed. Some input modules are designed for intrinsically safe circuits as well
as for electric position sensors (proximity switches) according to DIN 19234. Digital and analog outputs are also
available.
The HIMA PES are installed in subracks 19 inch 5 resp. 4 units high. The H41q system family is a compact system
consisting of a subrack holding all components such as central unit, power supplies, fusings, and power distribution,
as well as input/output modules.
The H51q system has a modular structure. A central rack 5 units high containing the central unit, interface port
extensions, monitoring, and power supplies may have up to 16 associated input/output subracks 4 units high.
The following diagram provides support in selecting the appropriate system for your PES task (see to the following
page):
Characteristic | H41q | H51q |
< 192 channels, single channel Note: 192 = 12 I/O modules x 16 channels/module. Max. number of I/O channels is reduced with modules having less than 16 channels (refer to the data sheets of the usable modules)
