Frequently Asked Questions (FAQ)
Q1: Is the 1746-IM16 compatible with all SLC 500 processors?
A: Yes, the 1746-IM16 is a standard input module compatible with all SLC 500 processors (e.g., 5/01, 5/02, 5/03, 5/04, 5/05) when used in the same chassis.
Q2: Can I power the module from an external 24V DC supply?
A: No, the module draws its operating power from the SLC 500 backplane (5V DC). The 24V DC is only for the field input signals. You must provide a separate 24V DC power supply for field devices.
Q3: What is the difference between sinking and sourcing wiring?
A: The 1746-IM16 supports both sinking and sourcing configurations. In sink mode, the module provides the current path to common; in source mode, the module switches the positive side. Check your field device compatibility and wire accordingly.
Q4: Does this module include a removable terminal block?
A: Yes, the 1746-IM16 comes with a 20-point removable terminal block (part number 1746-N2), making wiring and maintenance convenient.
Q5: Can I use this input module in a hazardous location?
A: The standard 1746-IM16 is not certified for hazardous (explosive) environments. For such applications, you would need an intrinsically safe barrier or a specialized module. Please consult your local safety regulations.
Q6: What is the typical lead time from Rossonix?
A: For in-stock items, we can ship within 1–3 business days via express or freight. Custom orders may take longer – please contact our sales team for current stock status.
Q7: Do you provide a warranty for this product?
A: Yes, we offer a standard 12-month warranty against manufacturing defects. Extended warranty options are available upon request.
Q8: Can I get a datasheet or manual for the 1746-IM16?
A: Absolutely. Please request the official Rockwell Automation manual (1746-UM001) from our sales team, and we will provide it digitally.
