- Simulate Dry Contacts
Solid state relay enables frequency calibrator
to simulate opening & closing of contacts to over 5
kHz.
- Read Dry Contacts
Supplies excitation current to allow a frequency
calibrator to measure an unpowered contact up to 2
kHz.
- Filters Out Contact Bounce
Adjustable circuit filters bounce from
mechanical contacts for accurate readings.

Extend the
usefulness of your Model 942 Frequency Calibrator to
measure and simulate a wide variety of relays,
mechanical pickups and other dry contact frequency
devices.
Calibrate inputs to your flowmeters, totalizers, SCADA,
telemetry systems, supervisory control systems and other
frequency control devices using the Model 942 with the
Model C-41 to simulate the remote sensor. Many of these
systems provide an excitation current or voltage which
the sensor interrupts to generate the frequency signal.
Coupled with the Model 942 Frequency Calibrator, the
Model C-41 simulates the contacts of these sensors to
calibrate these devices from 1 Count-per-hour to 5 KHz.
Check all your relays, mechanical contacts, cam driven
switches, photoconductive cells, and momentary contact
switches. The Model C-41 supplies an excitation current
which allows the Model 942 to read your dry contacts
from 10 Counts-per hour up to 2 KHz. An adjustable filter
on the Model C-41 combined with the trigger level
adjustment of the Model 942 allow a wide variety of
electronic and mechanical contacts to be measured.
Many mechanical contacts (relays, switches, etc.) bounce
when they are closed. This causes a ringing effect on
the waveform that is being generated. The Model C-41 has
an adjustable circuit that filters this effect and
allows the Model 942 Frequency Calibrator to measure the
correct frequency. |
