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.
