The eight signal outputs correspond one to one to the eight track outputs and are connected to the inputs of an s88 or s88-N feedback module. Alternatively, you can evaluate the signal directly with LEDs, for example for red illumination in a track diagram control panel.<\/p>\n<p>The current sensor needs only one input from the command station or booster and distributes the current across eight sections. All eight outputs are at the same potential: in the 2-rail system you always separate the same rail, in the 3-rail system the centre rail or both outer rails. You set the sensitivity for each output with a potentiometer. Thanks to spring terminals, the module is wired quickly and without soldering.<\/p>\n<h3>What else you need<\/h3>\n<ul>\n<li>an <a href=\"\/en\/product\/s88-n-rueckmelder-8-fach\/\">s88-N Feedback Module, 8-way<\/a> \u2013 it matches the Current Sensor 8\u00d73A exactly with its eight inputs<\/li>\n<li>for individual sections or FREMO modules: the <a href=\"\/en\/product\/stromfuehler-1x3a-gleisbelegtmelder\/\">Current Sensor 1\u00d73A<\/a><\/li>\n<li>current sensor and feedback module in one device: the <a href=\"\/en\/product\/16-fach-gleisbelegtmelder-s88-n\/\">s88-N Occupancy Detector, 16-way<\/a><\/li>\n<\/ul>\n<p class=\"jt-note\"><strong>Note:<\/strong> The current sensor only works on digitally operated layouts; analogue operation is not supported. The total current at the input must not exceed 3 A, and short-circuit detection must be active on the command station or booster.<\/p>\n<h2>Frequently asked questions<\/h2>\n<details>\n<summary>Do I need a separate feedback module as well?<\/summary>\n<p>If the signals are to reach your command station: yes, an s88 or s88-N feedback module with at least eight inputs. For a simple indication with LEDs in the control panel, you do not need a feedback module.<\/p>\n<\/details>\n<details>\n<summary>Can I read out the occupancy detection with an Arduino?<\/summary>\n<p>Yes. The signal outputs switch to GND. Connect the GND of the current sensor to the GND of the Arduino and the signal outputs to digital inputs with an internal pull-up resistor (INPUT_PULLUP). An occupied section is then read as LOW. Important: never connect the GND of the current sensor to the track.<\/p>\n<\/details>\n<details>\n<summary>Can I use several boosters?<\/summary>\n<p>All eight outputs are connected to one common input and therefore to one booster. For a second booster section, use another current sensor \u2013 or the s88-N Occupancy Detector, 16-way, whose two groups can be run from different boosters.<\/p>\n<\/details>","protected":false},"excerpt":{"rendered":"<p>The Current Sensor 8\u00d73A monitors up to eight track sections and reports occupied sections to an s88-N feedback module or to LEDs in the control panel.<\/p>\n<div class=\"jt-glance\">\n<p class=\"jt-glance-title\">At a glance<\/p>\n<ul>\n<li>8 monitored track sections, up to 3 A each<\/li>\n<li>H0 (2-rail and 3-rail), TT, N and Z<\/li>\n<li>DCC, Motorola, mfx and Selectrix<\/li>\n<li>Sensitivity adjustable per output, spring terminals<\/li>\n<li>Digital operation only<\/li>\n<\/ul>\n<\/div>","protected":false},"featured_media":245,"template":"","meta":{"_acf_changed":false,"jt_en_seo_title":"Current Sensor 8\u00d73A, Occupancy Detector | JT Digital","jt_en_seo_desc":"Current sensor with 8 outputs as an occupancy detector, 3 A per output, for H0 (2-\/3-rail), TT, N and Z.
