The other Specifications
• PID Function
• User program storage
User program is stored into FLASH memory automatically. During storing user program into FLASH memory OK LED blinks.
• RUN/STOP switch
There is a RUNSTOP switch to change the status RUN or STOP.
• Serial Communication
One RJ45 connector is available as RS-232C port. The other serial port will be available by using dedicated option board.
• On-line change
On-line change is available. Certain halt time appear if the on-line change is done by programming tool.
• RTC function
RTC function is available. If the battery is mounted, the data of RTC will be kept.
• Expansion unit
There is a connector to connect MICRO-EH series expansion unit. Four expansion units can be connected. This is the same
functionality of current MICRO-EH series.
• High speed counter
There are four channels of single phase counters or two channels of dual phase counters. These are selectable but don’t
operate at same.
• Pulse output
There are four channels of pulse outputs. It is possible to use as PWM pulse output.
• Option boards
There are three kinds of option boards. One is for RS-232C and 2ch analog inputs. One is for RS-485 and 2ch analog inputs.
One is just memory board. Memory board can be used RS-232C or RS-485 serial communication board together.
• Analog Input
There are two channels of Analog inputs on the option board of serial communication.
• Battery and Supper capacitor
It is possible to have battery to retain the data of data memory and RTC. There is one small supper capacitor on basic units.
