NOTE: Relays with other coil characteristics may be supplied
to meet specific application requirements.
250VDC operation may be obtained by wiring a 6,200
,
5 Watt resistor in series with the 110-125VDC coil. The
resistor must be mounted external to the A311.

The A311 Series Relay
is a sequencing version of the 219 series
general purpose relay. Contacts transfer on each Impulse to the coil.
Models are available with contacts transferring when coil is energized
or when de-energized. A double cam movement, one cam per snap
switch, allows one or both contacts to be energized or de-energized
with the cam rotating one half-step when the coil is energized and the
other half step when the coil is de-energized assures reliable sequencing
of the two SPDT snap switches.
