6.1 Mark VIeS YDOA Discrete Output Pack

YDOA Discrete Output Modules
The Discrete Output (IS420YDOAS1B) I/O pack provides the electrical interface
between one or two I/O Ethernet networks and a discrete output terminal board. The
pack contains a common processor board
discrete output function. The YDOA is capable of controlling up to 12 relays and
accepts terminal board specific feedback. Electromagnetic relays (with types TRLYS1B,
D, and F terminal boards) are available. Input to the pack is through dual RJ-45 Ethernet
connectors and a three-pin power input. Output is through a DC-37 pin connector that
connects directly with the associated terminal board connector. Visual diagnostics are
provided through indicator LEDs.
