Frequently Asked Questions (FAQ)
Q1: Can the 1747-NP1 be used with the SLC 5/01 processor?
Yes, the 1747-NP1 power supply is compatible with all Allen Bradley SLC 500 processors (5/01, 5/02, 5/03, 5/04, 5/05) when installed in the appropriate chassis (1746-A series). It provides the necessary +5V DC power for the processor and I/O modules.
Q2: What is the difference between 1747-NP1 and 1747-P1?
The 1747-NP1 is a newer revision (often marked as 'NP1') and may have improved component ratings or minor design updates. Both are functionally interchangeable in SLC 500 racks, but the NP1 is the latest available replacement part.
Q3: Does this power supply include a chassis or backplane?
No, the 1747-NP1 is just the power supply module. It must be inserted into a compatible SLC 500 chassis (e.g., 1746-A10, 1746-A13, etc.) that provides the backplane for power distribution.
Q4: What is the input voltage range? Can I use it with 220V single phase?
The 1747-NP1 has a selector switch for 120V or 240V input. For 220V operation, set the switch to the 240V position (170–265 VAC range). It accepts 50/60 Hz, making it suitable for most countries.
Q5: Is the 1747-NP1 still in production? Is it a new or refurbished unit?
Allen Bradley has officially phased out this module, but we offer both new-old-stock (NOS) and carefully tested used/refurbished units. Each unit is electrically tested and comes with a warranty. Please check with our sales team for current availability.
Q6: How can I verify the output voltage before installation?
We recommend using a multimeter set to DC volts. With the power supply installed in the rack and the AC input energized, measure across the +5V and common terminals on the backplane connector (if accessible) or use the test points on the module (if provided). The voltage should be 5.0 VDC ± 0.1 V.
Q7: What is the warranty period for this product?
Rossonix offers a standard 12-month warranty against manufacturing defects. Extended warranty or express replacement options are available upon request. Contact us for details.
Q8: Do you ship to my country? What about customs clearance?
We ship worldwide from our warehouses in Shenzhen, Hong Kong, and Europe. We handle export documentation; customs clearance in the destination country is the buyer's responsibility. Our shipping team can advise on Incoterms and typical transit times.
