6 YDOA Discrete Output Modules
6.1 Mark VIeS YDOA Discrete Output Pack
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 and an acquisition board specific to the
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.
