Relay Type
The 50-670A is fitted with ruthenium sputtered reed relays,
these offer very long life with good low level switching
performance and excellent contact resistance stability. Spare
reed relays are built onto the circuit board to allow easy
maintenance with minimum downtime.
All reed relays are manufactured by our Relay Division, for
more information please visit: pickeringrelay.com
Mechanical Characteristics
Single slot short PCI format.
3D models for all versions in a variety of popular file formats
are available on request.

PCI Compliance
The 50-670A card complies with the PCI Specification 2.0
(issued Feb 2004).
Signalling Environment: 33 MHz, 32-bit Universal
(+3.3 V & +5 V).
Safety & CE Compliance
All cards are fully CE compliant and meet applicable EU
directives:
Low-voltage safety EN61010-1:2010,
EMC Immunity EN61326-1:2013,
Emissions EN55011:2009+A1:2010.
Connections
User signals via a 200-pin female LFH* connector, for pin outs
please refer to the operating manual.
* LFH relates to the obsolete Molex connector series and is
retained for continuity, products will be fitted with a form, fit,
function Pickering equivalent connector that is intermateable
with the original Molex parts.
