Powering an SPD-100, SPD-700, or other frequency instruments
The SST-2000A/H has a repeater output that can be used to power external frequency instruments.
A square wave (14-volt peak-to-peak, zero-based, positive-going) is brought out at terminals 29 and 4 (common) to drive self-powered digital tachometers such
as the SPD-100, SPD-700, and MTH-103D, or to use as a conditioned high level signal source into counters or other instruments. The frequency of the signal is
equal to that being applied at the signal input: terminals 5 (+) & 6 (-).
This output has an internal resistance of 1 kD.
Using DPM-105 meters as external speed indicators
You can use the DPM-105 as an external indicator. You can connect one or more DPM-105 meters to your SST-2000A/H.
The 0-1 mA meter output of the SST-2000A/H [terminals 7 (-) and 8 (+)] is factory-calibrated into an external load of 40 Q. The load resistance of the DPM-
105 is 95 Q
Connecting one DPM-105
1 On the DPM-105, retain the jumper across terminals 1 and 2.
2 Connect the meter as shown in Fig. 3-3.

3 Calibrate the SST-2000A/H.
« Confirm the meter is properly connected to the SST-2000A/H.
* Use a frequency generator (e.g. F-16) to apply full-scale frequency
to terminal 5 (HI) & 6 (COM) on the SST-2000A/H. Maximum
signal input is 50 Vrms for a standard unit.
* Adjust the METER CALIBRATE potentiometer on the
SST-2000A/H for the appropriate full-scale reading on each
DPM-105.
* Use a DPM-105 data sheet, if necessary, to calibrate the
DPM-105 meters.
Connecting more than one DPM-105
1 Remove the jumper across terminals 1 and 2 on each DPM-105.
2 Connect the meters as shown in Fig. 3-4.

Powering Zero Velocity Pickups and Other Loads
The regulated 14 Vdc supply brought out at terminals 11 (+) & 4 (-) has a capacity of 40 mA. This output can power zero velocity pickups (e.g. M928) and
digital indicators like a DPM-105.
1 Connect the M928 pickup as indicated in Fig. 3-5.
2 Jumper terminals 11 and 30 to desensitize the input signal to a 1.0 V
threshold.
3 Adjust signal sensitivity if necessary. See page 27 for instructions on
how to adjust input sensitivity.

Driving an SPV-200 Solenoid Pneumatic Valve
WARNING: TO AVOID SPV-200 COIL DAMAGE
Use a current limiting resistor in series with the dc power source and the transferring relay contacts.
The SPY -200 coil has a resistance of 50 D and requires 6 Vdc to trip.
Switching the Regulated 14 Vdc Supply
The regulated 14 Vdc supply at terminals 11 (+) & 4 (-) does not have the capacity to drive the SPV-200 continually.
When the SST-2000A/H speed transmitter is supplied with the Pneumatic Trip Option for Overspeed, Relay 1 transfers for only 100 milliseconds on overspeed;
the 14 volt supply can then be used with a series limiting resistor to power the pneumatic trip.
Use a /4 watt, 47-50 Q resistor in series with the 14 volt supply.
