DESCRIPTION
The Model 850 Two Hand Control Module is designed to be
used with two palm or pushbutton switches, which must be
closed within 0.5 seconds of each other to operate machinery.
As long as both switches are pressed, the relay will remain
energized in the continuous mode.
For applications requiring a pulse to initiate operations, the
Model 850 can be set to produce a pulse output by connecting
a resistor to pins 4 and 7. The resistor value in ohms should be
100,000 times the desired time in seconds (R=100,000 x T).
The internal relay de-energizes on completion of the pulse,
even if both switches are depressed. The relay de-energizes
immediately, if either hand switch is released, in standard or
pulsed mode.
The compact size of the Two-Hand Control Module allows
installation into an existing control panel. It can be used with
any type of machinery requiring safe, two-handed operation
such as presses, punches, cutters, etc. The standard nominal
supply voltages are 120VAC, 240VAC, 24VAC, 24VDC.
Other voltage versions may be available by special request.
