6. Basic A/B Cards
Basic A/B Switch Cards provide circuit switching individual or gang applications and can be controlled remotely
thru the network control card, external contact closures, or locally from front panel switches. Magnetic latching
relays maintain selected circuit connectivity, A or B, in the event of a power loss. Automatic switching can be
arranged using features in the IPC-1-
R Network control card, such as “Auto Ping” where switching is activated as
the result of the loss of response from a networked device. See “A “Auto Ping” on page 28 for more detail.
6.1. A/B Cards, Current Models
All A/B cards listed below use relay switching and are compatible with any communications interface and
switching up to 10Mbps, or as noted. All connectors are female gender except as noted below. All support the full
complement of leads.
