D61538 110v Input Isolator Board
D61539 24v Input Isolator Board
Revision 1

Instruction Manual
The D61538 / D61539 Input Signal Isolator Boards are for use with
Drivecon Crane Commander ES (CCES) and Commander ES (CES)
series of variable frequency drives. They are designed to accept
external 110vac or 24vac inputs from switch or relay contacts. The
D61538 will accept 110-120vac signals and the D61539 will accept
24vac input signals. The D61538 will not function with 24vac input
signals and the D61539 will be damaged if used with 110vac input
signals.
Either model of input isolator boards will provide direction [run
forward / run reverse] and up to 2 additional preset speeds. If the two
additional preset speeds are not required, then those inputs can each
be assigned a different function from a list of seven available
functions. Four red LED indicators are provided for the “Fwd”,
“Rev” and each of the two programmable inputs to show when the
input is activated. A programmable “dry” Form A relay contact is
available that can be programmed to one of four available functions. Terminals are provided to connect an
external speed reference potentiometer or an external analog speed reference signal. Also available are
terminal connections for an analog 0 - 10vdc output representing output frequency.
* For use with Commander ES only. Direction frequency should be set up from keypad by scrolling up or
down with arrow keys. The priority of reading frequency setting is: JOG, SP1, and keypad setting.
