INTRODUCTION
The
SPSR-IM
Self Powered Sensor Interface Module
is a self-contained,
rechargeable battery powered device for developing a TTL compatible one
pulse per revolution output for triggering external equipment such as vibration
analyzers, spectrum analyzers, stroboscopes, data acquisition equipment,
tachometers, balancers, waveform analyzers and magnetic tape recorders.

comprised of the
SPSR-IM
Interface Module
, which
provides power to a sensor
and couples the sensor to a
BNC output; an input sensor
with a visible red LED light
source (
ROS-P
); and a battery
recharger.
Optional sensors such as an optical
laser sensor (
ROLS-P
-not shown),
infrared sensor (
IRS-P
), or an
amplified magnetic sensor (
MT-
190P
) may also be combined with the
SPSR-IM Interface Module
when
appropriate. (See separate instructions for these configurations.)
FUNCTIONS AND OPERATION
SPSR Interface Module
The
SPSR Interface Module
(
SPSR-IM
) provides power to the input
sensor, receives and optionally inverts the return pulse signal, and provides
a switch selectable positive going 0 to 5 Vdc or negative going 5 to 0 Vdc

pulse train trigger output on a BNC connector. Connections and operation
are common to all SPSR models. Fully charged internal NiMH batteries will
typically provide greater than 40 hours of continuous operation. In addition,
the SPSR system can be operated continuously on external power by use of
the recharger/power supply provided.
Connections
Connect the input sensor via the 1/8” [3.5 mm] phone plug to the mating
connector on the
SPSR-IM
. This sensor may remain connected even
when recharging the internal batteries of the
SPSR-IM
.
NOTE:
Do not plug an input sensor into the SPSR with the Power
switch in the “ON” position. Before plugging the sensor in, switch the
power to “OFF” and unplug any external power supply.
Connect the output signal cable to the BNC connector on the opposite
end of the
SPSR-IM
and to the external equipment to be triggered.
If operating from the recharger/power supply, connect the recharger to
the connector marked “External DC” on the
SPSR-IM
and connect the
wall unit to the appropriate power source.
Controls
The “Power” switch on the
SPSR-IM
controls both the operation and the
charging of the system. The unit will only charge from external power
in the power OFF position. In the power ON position, the unit will
operate directly from external power any time that it is being supplied.
Otherwise, it functions on internal battery power.
The “Output Selection” switch determines the polarity of the leading
edge of the TTL compatible output signal. In the NON-INVERTING
position, the output signal on the BNC connector will be a negative going
5 to 0 Vdc pulse derived directly from the conditioned sensor output.
When the INVERTING position is switch selected, the BNC output
signal will be a positive going 0 to 5 Vdc, TTL compatible.
