Hardware Specifications

Backplane Bus Communication Interface

The 1734-MB functions as the mechanical and electrical foundation for POINT I/O assemblies. It provides continuity between the POINTBus backplane and field power distribution paths while supporting module attachment through the integrated terminal block arrangement. The mounting base allows expansion of distributed I/O structures by providing a standardized connection point for compatible POINT I/O modules and terminal assemblies.

Frequently Asked Questions

Q: Does the 1734-MB contain active I/O electronics?
A: No. The 1734-MB operates as a mounting and interconnection base that provides mechanical support and electrical routing between the backplane and field power bus.

Q: Are removable terminal blocks supported?
A: Yes. The mounting base supports removable terminal block functionality and incorporates an inbuilt removable terminal block design.

Q: Can the 1734-MB be used with different POINT I/O terminal module types?
A: Yes. The unit is specified as compatible with both POINT I/O common terminal modules and POINT I/O voltage terminal modules.

Field Installation Guidelines

• Install the mounting base on a properly secured DIN rail before attaching POINT I/O modules.

• Verify complete engagement between adjacent bases to maintain backplane continuity.

• Inspect terminal block contacts for contamination or mechanical damage prior to wiring.

• Route field wiring to minimize mechanical stress on terminal connections.

• Maintain separation between low-level signal conductors and high-current power wiring where applicable.

• Confirm environmental conditions remain within the specified operating limits of 0 to 40 deg C and a maximum relative humidity of 80% non-condensing.

• Ensure all field wiring is terminated and secured before energizing the field power bus.
