Frequently Asked Questions

What does the 1734-FPD module do in a POINT I/O system?
The 1734-FPD breaks the field power distribution bus. It allows you to change the field power distribution source for I/O modules to the right of the module, enabling logical or functional partitioning of low-channel-count, high I/O-mix applications. It passes through all POINT I/O backplane signals except the internal field power bus for field devices.
What voltage ranges does the 1734-FPD support?
The module supports 12V DC and 24V DC nominal (10…28.8V DC range) for DC applications, and 120V AC and 240V AC nominal (50/60 Hz) for AC applications. The field power bus supply voltage maximum is 264V AC.
What is the maximum current the 1734-FPD can handle?
Both the input current maximum and the field power bus supply current maximum are rated at 10 A.
Is the 1734-FPDK different from the 1734-FPD?
The 1734-FPDK is the conformal coated version of the 1734-FPD. Its specifications are identical to the non-conformal coated catalog number.
What hazardous location approvals does the 1734-FPD carry?
The module is UL-listed for Class I Division 2, Group A, B, C, D hazardous locations (UL File E194810). It also carries UKEX/ATEX and IECEx approvals for Zone 2 (II 3 G Ex ec IIC T4 Gc), and CCC certification for explosion-proof electrical products.
What DIN rail is specified for mounting the 1734-FPD?
The publication specifies Allen-Bradley part number 199-DR1 (also 46277-3, EN50022). Zinc-plated chromate-passivated steel DIN rail must be used to assure proper grounding. The DIN rail should be secured to the mounting surface approximately every 200 mm (7.8 in.).
What wire sizes are compatible with the 1734-FPD terminal block?
The module accepts 0.25…2.5 mm² (24…14 AWG) solid or stranded copper wire rated at 75 °C (167 °F) or greater, with a maximum insulation diameter of 1.2 mm (3/64 in.).
