IS220PDOAH1B provides the electrical interface between the Mark VIe I/O Ethernet network and a compatible discrete-output terminal board. The pack processes output commands, controls as many as 12 relays and receives terminal-board feedback.
Output capability is system-dependent: relay type, contact voltage and contact current are established by the connected TRLY or SRLY terminal board.

Return support: Contact us within seven days if an issue appears after receipt. Keep the item in its original condition and state the reason. Return or replacement handling begins after receipt and inspection; return freight is arranged by the buyer.
Does IS220PDOAH1B directly provide the field-contact rating? No. The connected TRLY or SRLY terminal board determines relay construction and contact capacity.
02
How many relays can IS220PDOAH1B control? It controls up to 12 relay outputs and receives terminal-board-specific feedback.
03
Can IS220PDOAH1B be used in simplex and TMR systems? Yes, with the correct terminal board, network connections and Mark VIe configuration for the required redundancy.
04
Is IS220PDOAH1B compatible with every discrete-output board? No. Confirm an approved TRLY or SRLY execution. It is not a universal replacement for unrelated discrete-output hardware.
05
What should accompany an IS220PDOAH1B compatibility request? Provide the I/O-pack label, terminal-board number, system redundancy, relay load ratings, wetting supply, feedback option, controller release, quantity and delivery date.
