Frequently Asked Questions (FAQ)
Q1: Is this a genuine Allen‑Bradley product or a third‑party replacement?
A: This is a genuine Allen‑Bradley (Rockwell Automation) 1746-RT35 terminal block. Rossonix sources parts directly from authorized distributors and verified surplus stock to ensure authenticity.
Q2: Which SLC500 modules is this terminal block compatible with?
A: It is designed for all 1746 I/O modules that require a 35‑point terminal block, such as 1746-IA16, 1746-IB16, 1746-IC16, 1746-OA16, 1746-OB16, 1746-OV16, 1746-NI8, 1746-NO8I, and many others. Always verify your module’s manual for the correct terminal block part number.
Q3: Can I use this terminal block with a SLC500 processor module (e.g., 1747-L531)?
A: No, processor modules use a different connector (usually a ribbon cable). The 1746-RT35 is strictly for discrete or analog I/O modules that have a 35‑position terminal interface.
Q4: What wire gauge is recommended?
A: Typically #22 AWG to #14 AWG stranded or solid copper wire is acceptable. The screw terminals can accommodate up to 2.5 mm² (approx. 14 AWG). Use wire ferrules for stranded wires if desired, though not mandatory.
Q5: How do I mount the terminal block?
A: The terminal block snaps directly onto the front of the I/O module after aligning the keying slots. No tools are required for mounting. Ensure the locking tabs engage fully for a secure fit.
Q6: What is the torque specification for the terminal screws?
A: The recommended tightening torque is 0.5–0.6 N·m (4.4–5.3 lb·in). Over‑tightening may strip the threads or damage the terminal. Use a calibrated screwdriver if available.
Q7: Does this product come with a warranty?
A: Yes, Rossonix provides a standard 12‑month warranty against manufacturing defects. Please check our terms for extended coverage. The warranty does not cover damage caused by misuse or improper installation.
Q8: What is the minimum order quantity (MOQ) and lead time?
A: MOQ is 1 piece for stock availability. For quantities above 10 pieces, please contact us for lead time (typically 2–5 working days from our Shenzhen warehouse or 5–10 days from European stock). Payment terms: T/T, PayPal, or credit card for small orders.
