The Hitachi EH-150 PLC is the smallest yet for its capabilities. The new micro PLC offers the benefits of larger expandable rack units. At the heart of the system are two CPU options giving up to 8000 steps and 256 I/O. Despite its size, the EH-150 has high function ability with a modem port and an expansion unit allowing for 16 extra slots.

The EH-150 offers high-speed communication at 38,400bps, with a basic processing speed of 1microsecond or less and an application processing speed of several microseconds. Battery back up is available for the built-in RAM.

All components are CE approved to EMC and the Low Voltage Directive. Like all the other Hitachi PLCs from HID, the powerful MS Windows based Actwin software tools make programming simple.
