1336ĆMODĆL3 115V AC

The 115V AC Logic Interface Board provides a means of interfacing

Logic Interface Board

various signals and commands to the 1336VT drive using 115V AC
signals. A 115V AC power source must be supplied by the user for the
board to operate. Plug in connectors on the 115V AC Interface Board allow
it to be plugged directly into connectors on the Main Control Board. Two
mounting thumb screws secure the board in place.

!

ATTENTION: If the 115V AC Interface Board is to replace either
the 1336-MOD-L1 or 1336-MOD-L2, external circuits must be
reconfigured to operate at the 115V AC logic potentials required by
the board. The application of either +5V DC or +24V AC to the
115V AC Interface Board will damage both the 115V AC Interface
Board and the Main Control Board

Operation

Each of the twelve terminals on the board are defined as being either a user
command input signal or interface common.

When a closed circuit is present between a terminal and interface common,
a 115V AC potential will exist. This represents the selected state or high =
True.

When an open circuit is present between a terminal and interface common,
the input will go lower to a False state.

Requirements

Circuits used with the 115V AC Logic Interface Board must meet the
following criteria:

Circuits must be capable of operating with high = True logic.

In the low state, circuits must generate a voltage of no more than 10.0V
AC. The leakage current must be less than 1mA into a 13k

load.

In the high state, circuits must generate a voltage of 115V AC

±

10% and

source a current of approximately 8.5mA for each input.
