The Series 114 is a range of Single-In-Line reed
relays intended for power levels that are beyond the
capabilities of conventional dry SIL reed relays.
The more usual dry relays are rated at 0.5 amps at 10
Watts. The Series 114 have a rating of 1 amp switching
at up to 40 watts and will carry 2 amps. In many cases,
this higher rating will allow them to be used as an
alternative to mercury wetted reed relays.
Unusually for high power relays, they feature sputtered
ruthenium contacts instead of the more common
electroplated rhodium or tungsten types. This makes
them suitable for low level or “dry” switching also.
They are able to switch a.c. mains voltages so are
suitable for interfacing to larger electromechanical relays
or contactors. It is important however, to surpress back
EMFs from inductive loads. This is achievable by using
an RC snubber, varistor or similar voltage limiting device.
One or two Form A (energize to make) or One Form B
(energize to break) configurations are available.
The range features an internal mu-metal screen
to minimize problems that would otherwise be
experienced due to magnetic interaction when they are
closely stacked.

zz SoftCenter™ construction (see reverse)
zz 2 Form A (energize to make)
200 Volts dc or 240 Volts ac rms switching at up
to 40 Watts. 500 Volts dc or ac peak stand-off
zz 1 Form B (energize to break)
200 Volts dc or 240 Volts ac rms switching at up
to 40 Watts. 500 Volts dc or ac peak stand-off
Form A versions may be stacked side-by-side.
Due to the fact that the Form B types feature an
internal biasing magnet, a gap of 0.4 inches minimum
should be left between adjacent relays.
