Model 63 Rev. C or D. Motor control with keypad interface and display.
Replacement for materials handling equipment no longer supported by original supplier.
Data from tachometers, flowmeters and counters can be scanned along
with data from analog sources using the Model 108. Each of 8 channels
will accept a pulse stream from virtually any source and convert it to a
voltage proportional to the input frequency. Each channel has its own
full scale frequency adjustment.
INPUT FREQUENCY RANGE
0 to 5KHz
Note: Range can be extended to 0-10KHz by trimpot adjustment.
Other ranges are available as factory options.
MODEL 125 ULTRA-RELIABLE PRECISION POWER REFERENCE
zoom
The Model 125 generates an extremely stable reference voltage with over
one amp of current sourcing available. The standard output voltage is
8 VDC, although any voltage from 4 to 20 volts can be suppled as a factory
option. The Model 125 is optimized for bridge and strain gauge excitation.
The Model 35B 16-Channel Differential Amplifier in combination with the
Model 125 yields an economic multi-bridge system. A DC voltage source,
regulated or unregulated, is required. The price listed is without
enclosure or DC voltage source.
MODEL 11 TEMPERATURE STABILIZED BRIDGE AMPLIFIER
zoom
The Model 11 is a function module designed for mounting on a circuit board.
It can provide excitation and amplification for almost any bridge type sensor.
When using the Model 57, three jumper programmable gains are available,
corresponding to bridge sensitivities of 1, 2, or 4 millivolts per volt.
For the standard Model 11, gain is fixed at 500. Optional custom gain settings
up to 1000 are practical. Standard excitation is 7.5 volts with sufficient
current for one 120 ohm or four 350 ohm bridges. The Model 11 normally
controls its internal temperature to 42 degrees Centigrade. If ambient
temperature is expected to reach that, an external resistor can be used
to raise the set point. A linear power supply is recommended for best
stability.
SIZE
2.25 X 2.25 X .625 inches with its thermally insulating cover.
POWER REQUIREMENT
+12 to +15 VDC @ 300 MA
-8 to -15 VDC @ 80 MA
linear supply recommended
A 2MV/V Gage gives an output from -4.5 to +4.5 volts
LINEARITY
0.005% of full scale
SETTLING TIME
125 Milliseconds to 20 bits
DC COMMON MODE RANGE
0 to 6 volts
COMMON MODE REJECTION RATIO
-100 dB typical
TEMPERATURE CONTROL POINT
45 deg. C nominal (can be raised with external resistor)
PRICE
$200.00 (add $5 for optional insulating cover)
INSTALLATION RECOMMENDATIONS
For best results the Model 11 should be mounted in a
shielded enclosure with insulating material packed tightly
around all six sides of the module. If the enclosure is
warmer than 42 deg. C, an external resistor should be used
to raise the temperature control point.
