Model 60-12G

The Model 60-12G is a modified 60-12F, in which C5 has been jumpered out. See
Figure 3-4. The 60-12G puts out 100 pulses per revolution, and has an RPM range
of 10 to 200 RPM. The output frequency is determined as follows: RPM x 1.666 =
Hz. As with the 60-12F, the 60-12G puts out approximately the voltage supplied at
terminal 17. See Figure 3-3. The 60-12G requires an external power source of 15 to
30 VDC to operate.

Model 60-12 ENC

The Model 60-12 ENC (500) has a 500 pulse per revolution encoder with an internal
pull up resistor. The output is approximately the voltage supplied at Terminal 17.
See Figure 3-3. The 60-12 ENC requires an external power source of 5 to 24 VDC
at 60 mA to operate.
