IS220PDIOH1B GE MKVIe PDIO I/O Pack IS230TDBTH2A

Description:

The Discrete Input/Output (PDIO) pack provides the electrical interface between one or two I/O Ethernet networks and a discrete input/output terminal board. The pack contains a processor board common to all Mark* VIe distributed I/O packs and an acquisition board specific to the discrete input/output function. The pack accepts up to 24 contact inputs, controls up to 12 relay outputs, and receives terminal board specific feedback signals. The associated terminal board determines voltage capability of PDIO. System input to the pack is through dual RJ45 Ethernet connectors and a three-pin power input. Discrete signal input/output is through a DC-62 connector that connects directly with the associated terminal board connector. Visual diagnostics are provided through indicator LEDs.

PDIO is the functional equivalent of a PDIA and PDOA I/O pack combined into a single assembly. For simplex applications, it goes on a TDBS terminal board that is the equivalent of a SRLY relay terminal board combined with a STCI contact input terminal board. For TMR applications, it goes on a TDBT terminal board that, with the WROB option, provides the equivalent of a terminal board combined with a TBCI contact input terminal board.

To install the PDIO pack

1. Securely mount the desired terminal board.
2. Directly plug the PDIO I/O pack into the terminal board connectors.
3. Mechanically secure the packs using the threaded studs adjacent to the Ethernet ports. The studs slide into a mounting bracket specific to the terminal board type. The bracket location should be adjusted such that there is no right-angle force applied to the DC-62 pin connector between the pack and the terminal board. The adjustment should only be required once in the life of the product.
Note The PDIO mounts directly on a Mark VIe terminal board. Simplex terminal boards have a single DC-62 pin connector that receives the PDIO. TMR-capable terminal boards have three DC-62 pin connectors, one used for simplex operation, two for dual operation, and three for TMR operation. PDIO directly supports all of these connections.
4. Plug in one or two Ethernet cables depending on the system configuration. The pack will operate over either port. If dual connections are used, the standard practice is to connect ENET1 to the network associated with the R controller.
5. Apply power to the pack by plugging in the connector on the side of the pack. It is not necessary to remove power from the cable before plugging it in because the I/O pack has inherent soft-start capability that controls current inrush on power application.
6. Use the ToolboxST* application to configure the I/O pack as necessary. See also the Auto-Reconfiguration section.

Operation
The function and on-board signal conditioning are the same as those on TBCI, they are scaled for 24, 48, and 125 V dc excitation. The input excitation range is 16 to 32 V dc, 32 to 64 V dc, and 100 to 145 V dc respectively. The threshold voltage is 50% of the excitation voltage. The contact sensing circuits are shown in the figure.

Contact input currents are resistance limited to 2.5 mA on the first 21 circuits, and 10 mA on circuits 22 through 24. The 24 V dc supply is current limited to 0.5 A using polymer positive temperature coefficient fuses that can be reset.

Filters reduce high-frequency noise and suppress surge on each input near the point of signal entry. The discrete input voltage signals go to the I/O processor which passes them through optical isolators, converts them to digital signals, and transfers them to the controller.
