Remote Termination Blocks

This 1734D input/output module is a DIN-rail mounted device with an integrated DeviceNet communication interface, 8 ac inputs and 8 ac outputs, removable terminations, and a PointBus expansion port.The expansion port allows you to add up to 12 additional POINT I/O modules. The module includes a non-isolated DeviceNet communication interface. The 24V dc from the DeviceNet connection powers a non-isolated dc/dc converter that generates +5V dc which powers the POINTBlock electronics and connects to the PointBus port to power the expansion I/O electronics.

The 1734-IA8XOA8 uses cage-clamp terminations, and the 1734-IA8XOA8S uses spring-clamp terminations.

ATTENTION

Whatever field power you supply is connected to the internal field-power bus. For example, if

120V ac is applied to the power connections,

!

there will be 120V ac applied to the modules through the internal field-power bus.

POINT I/O modules to the right of the module will also have that internal power bus voltage applied, unless you use a 1734-FPD to interrupt and change the field power-bus voltage.

ATTENTION

POINTBlock is designed to be grounded through the DIN rail to chassis ground. To assure proper grounding of POINTBlock and POINT I/O

!

adapters and terminal bases to chassis ground, the recommended DIN rail material is zinc-plated, yellow-chromated steel. Mount POINTBlock, POINT I/O adapters and terminal bases only to zinc-plated, yellow-chromated steel.

To set the node address, set the combination of 1’s and 10’s to correspond to the required address. (For example, for 61, set the 10’s switch to 6 and the 1’s switch to 1.)
