The 114-1-B-5/1 is a high-power Single-In-Line reed relay from Pickering Electronics, designed for applications requiring robust switching capabilities. It features a Form B configuration (energize to break) and is rated for switching up to 40 watts with a maximum switching voltage of 200 volts DC or 240 volts AC RMS. The relay can carry a maximum current of 2 amps and has a life expectancy of approximately 10 million operations under maximum load conditions. This relay utilizes sputtered ruthenium contacts, making it suitable for both low-level and dry switching applications. It is equipped with an internal mu-metal magnetic screen to reduce magnetic interaction when stacked, although a minimum spacing of 0.4 inches is required between adjacent Form B relays due to their internal biasing magnet. The relay operates within a temperature range of -20 to +85 ¬8C, with the potential for extended operation up to +125 ¬8C if the coil drive voltage is adjusted accordingly. Engineers considering this relay should note the importance of suppressing back EMFs from inductive loads, which can be managed using an RC snubber or similar devices.
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.
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.
