This lets you tune out common-mode line noise. Selecting a higher Vsp prevents noise spikes from being registered as valid pulse signals, preserving system accuracy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the primary advantage of a solid-state safe-area output over a mechanical relay output?\u003c\/strong\u003e\u003cbr\u003eSolid-state outputs have no mechanical contacts to wear out, which is crucial for high-frequency pulse applications. For instance, a flowmeter running at 10 kHz would destroy a mechanical relay in minutes. The solid-state output easily handles high-speed switching with zero physical wear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this barrier to isolate standard 4-20mA analog transmitter loops?\u003c\/strong\u003e\u003cbr\u003eNo, this module is designed exclusively for pulse and digital inputs. It does not possess the operational analog circuitry needed to pass a proportional 4-20mA loop. For analog signals, we recommend using the MTL5040 series isolators.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the output turn off if the main power supply fails?\u003c\/strong\u003e\u003cbr\u003eThis is an integrated fail-safe design. If the 24Vdc supply fails, the safe-area solid-state output drops to its off-state (maximum 35V, 10µA leakage). This ensures the downstream PLC or controller registers a safe, zero-speed or zero-flow condition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the maximum cable resistance allowed when connecting a NAMUR proximity sensor?\u003c\/strong\u003e\u003cbr\u003eThe input meets NAMUR standards (DIN 19234). We recommend keeping the total loop resistance below 50 Ohms to prevent signal attenuation.
