PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1734-FPD/B (Series B). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1734-FPD is a POINT I/O field distributor module. It breaks the field power distribution bus for adjacent modules installed to its right. Control logic backplane communication signals pass through the module directly. The unit supports AC and DC field power inputs across distributed automation architectures.
This module accepts field power inputs of 10 to 28.8 V DC or 120/240 V AC. It supplies a maximum field power bus current of up to 10 A. The device mounts onto standard DIN-rail assemblies in horizontal or vertical orientations. It operates across an ambient temperature range from -20 to +55 °C.
