The suffix difference may indicate barrier vs. non-barrier configuration, approval option, or minor revision. For exact differences, consult the Bently Nevada 3500\/42M ordering information or contact technical support.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is the 80074-01 compatible with monitors other than the 3500\/42M?\u003c\/strong\u003e\u003cbr\u003eA: The 80074-01 is specifically designed for the \u003cstrong\u003e3500\/42M Proximitor\/Seismic Monitor\u003c\/strong\u003e. For other 3500 monitor modules (e.g., 3500\/40M, 3500\/45), use the I\/O modules specified in those monitor's datasheets.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the 80074-01 require external power?\u003c\/strong\u003e\u003cbr\u003eA: No. The 80074-01 is a \u003cstrong\u003epassive connection block\u003c\/strong\u003e that draws power directly from the 3500 rack backplane through the connected 3500\/42M monitor module. No separate power wiring is required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use the 80074-01 with the 3300 monitoring system?\u003c\/strong\u003e\u003cbr\u003eA: No. The 80074-01 is designed for the \u003cstrong\u003e3500 series\u003c\/strong\u003e monitoring system only. For 3300 systems, use the appropriate 3300-series I\/O terminal boards.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the maximum number of transducers per 80074-01?\u003c\/strong\u003e\u003cbr\u003eA: The 80074-01 supports \u003cstrong\u003eup to 4 transducer channels\u003c\/strong\u003e, matching the 4-channel capacity of the 3500\/42M monitor module.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What cable type should I use for transducer connections?\u003c\/strong\u003e\u003cbr\u003eA: Use shielded coaxial cables for proximity probe connections and shielded twisted-pair cables for seismic\/velocity sensor connections.
