The module features selectable input impedance and pull-up resistor settings (68 kOhm) to accommodate diverse signal sources, including voltage pulses (+3 to +24 VDC) and dry contact closures. Integrated power supply circuitry provides selectable 12 VDC or 24 VDC excitation for 3-wire sensors, with current limiting set at 40 mA to protect internal components against field-side short circuits.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the APM11 support hot-swapping in an active I\/O nest?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The module is designed for replacement during system operation. However, the user must ensure that the field wiring is appropriately isolated or the associated loop is set to manual\/test mode within the control software to prevent process disturbances during the transient state of module extraction.\u003c\/p\u003e\n\u003cp\u003eQ: How is the shunt resistance configured for current pulse inputs?\u003c\/p\u003e\n\u003cp\u003eA: Shunt resistance is selectable via the module hardware interface (200, 510, or 1000 Ohm) or OFF for voltage-only applications. Correct selection is necessary to match the output impedance of the field flowmeter to ensure the signal voltage remains within the operational threshold of -1 to +8 VDC (Low) and +3 to +24 VDC (High).\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring:\u003c\/strong\u003e Utilize shielded twisted-pair cabling for all pulse inputs.

Loose connections on high-frequency pulse inputs can manifest as erratic count values or \"double-counting\" due to contact bounce or induced noise.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43616367345754,"sku":"APM11","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/476._db92a46a-5865-47aa-a85e-eca47e2c56a0.jpg?v=1783477514","url":"https:\/\/www.spareoil.com\/ar\/products\/yokogawa-apm11-s3-centum-cs-vp-pulse-input-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
