Remote Termination Blocks

This 1734D input module is a DIN-rail mounted device with an integrated DeviceNet communication interface, 16 ac inputs, 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 1734D-IA16 uses cage-clamp terminations, and the 1734D-IA16S uses spring-clamp terminations.

I/O Connections

41971

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 this module will have this 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.

Installing the POINTBlock 16 Input Module

To install the 16 Input module on the DIN rail, proceed as follows:

1. Position the block module vertically above the DIN rail.

2. Press down firmly to install the module on the DIN rail. (The

locking mechanism will lock the module to the DIN rail.)

Do not discard the end cap. Use this end cap to cover the exposed interconnections on the last mounting base/block module on the DIN rail. Failure to do so could result in equipment damage or injury from electric shock.

If installing a replacement POINTBlock module to an existing system:

1. To remove the block module from the DIN rail, pull up on the

RTB removal handles to remove the terminal blocks.

2. Use a small bladed screwdriver to rotate the orange DIN rail

locking screw to a vertical position. This releases the locking mechanism.

3. Lift straight up to remove.

4. Position the replacement block module vertically above the

DIN rail.

5. Slide the block module down allowing the interlocking side

pieces to engage the adjacent module/adapter.

6. Press firmly to seat the block module on the DIN rail. The

module locking mechanism will snap into place.
