easy for the user to change control configurations through
the RS232 interface which has 1500VAC isolation from
the electronic circuitry virtually eliminating interference

the computer may be disconnected and the controller becomes
a stand alone unit or the computer can remain connected

delivers a load current of .1 to 25 Amps.
