CAUTION
Determine maximum power supply voltage after
determining maximum allowable voltage of all
electronic devices in the system.

COIL_B /.
COIL_A
Any magnetic (variable-reluctance) pickup coil can
drive this input. Minimum signal amplitude is 10 mV
P-P. Maximum recommended signal amplitude is
1V P-P. Shielded cable may be used to increase
distance.
HI-F_IN.
Either open-collector or active-drive signals are
accepted. If active-drive, signals of 5V to 12V P-P
amplitude are acceptable. Maximum frequency is
approximately 1000 Hz. Note: Optional to route a
reed-switch signal directly to this input.
LO-F_IN.
A reed switch may be connected directly between
this terminal and any
frequency is approximately 150 Hz.
OC_OUT.
• This is an open-collector or current-sinking out-
put when NO JUMPER is attached at OUTPUT
P.U.R. location. It can sustain closed-circuit
current of up to 200 mA and open-circuit voltage
of up to 60V.
• This is an active-drive output when the JUMPER
(supplied) is attached at location OUTPUT P.U.R.
The JUMPER applies an internal 10K Ohm resis-
tor as a "pull-up" to the regulated power supply
of 5.5V.
• The output ground circuit may be connected to any
COM
terminal.
• Do not use JUMPER if operating from a battery;
it will cause significantly increased system
current consumption.
• CAUTION: Only use JUMPER when the receiving
equipment has a active-drive input with 5V or less.
COM.
All COM terminals are internally connected and may
be used either as NEGATIVE power supply termi-
nals or return terminals for any inputs or outputs.
