The EHV series is available in a range of sizes and up to 66 modules can be built up into a bespoke controller for any given application.
Hitachi has refined data processing speeds with the launch of its new EHV series programmable logic controller (PLC).
The CPUs at the heart of the controller scan at 20 nanoseconds per instruction, 80% faster than the current fastest units and many many times faster than PLCs just a few years old.
The EHV series is available in a range of sizes and up to 66 modules can be built up into a bespoke controller for any given application.
The program memory capacity ranges from 96 to 768Kbyte.
The EHV, available in the UK through Silverteam , was developed in response to demand for smaller, faster systems that are easy to develop and install.
The backbone of the concept is four fully compatible CPUs, which are all identical except the memory capacity (96, 192, 384 and 768Kbyte).
These can be configured onto a standard backplane in any arrangement and used alongside the many specialist modules used to give each system its own capabilities.
A full set of communications interfaces is provide as standard.
