It supports input frequencies up to 10 kHz and provides electrical isolation between the field inputs, individual channels, and the system. The \/K4A00 ordering option specifies a KS Cable Interface Adapter.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe AAP135 receives pulse signals from field devices and converts them into count data for processing by the control system. It supports both two-wire and three-wire input arrangements, including contact signals and externally powered pulse signals.\u003c\/p\u003e\n\u003cp\u003eIts eight input channels are electrically isolated from one another and from the system side. This separation helps limit the propagation of electrical disturbances between field signal circuits.\u003c\/p\u003e\n\u003ch3\u003eInput Signal and Counting Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe module accepts three principal signal types:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eContact ON\/OFF: Signals from relay contacts or transistor contacts.\u003c\/li\u003e\n\u003cli\u003eVoltage pulse: Voltage-level pulse signals from field instruments.\u003c\/li\u003e\n\u003cli\u003eCurrent pulse: Current-based pulse signals, internally converted to voltage for input processing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe input frequency range of 0 to 10 kHz supports pulse-counting applications where signal frequency represents the operating rate or accumulated quantity of a field process. The minimum input pulse width is 40 us.\u003c\/p\u003e\n\u003ch3\u003eElectrical Isolation and Signal Conditioning\u003c\/h3\u003e\n\u003cp\u003eThe module provides withstand voltage of 500 V AC for 1 minute between the input and system sides, and between individual input channels. This isolation arrangement allows separate field signal circuits to be connected without directly sharing their signal reference.\u003c\/p\u003e\n\u003cp\u003eAdditional signal-conditioning functions include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSelectable shunt resistance: None, 200 ohm, 500 ohm, or 1000 ohm.\u003c\/li\u003e\n\u003cli\u003ePull-up resistance: 68 kohm, selectable for 12 V

AAP135-S53\/K4A00 receive both contact and voltage pulse signals?\u003c\/p\u003e\n\u003cp\u003eA: Yes. It accepts contact ON\/OFF, voltage pulse, and current pulse signals. The appropriate field wiring and input configuration depend on the signal source and connection method.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 10 kHz input frequency apply to all contact input configurations?\u003c\/p\u003e\n\u003cp\u003eA: No. The general input frequency specification is 0 to 10 kHz, but the frequency is limited to 0 to 800 Hz between terminals B and C when receiving non-voltage contact signals. This distinction should be considered when selecting the input wiring.\u003c\/p\u003e\n\u003cp\u003eQ: Is the AAP135-S53\/K4A00 suitable for dual-redundant configurations?\u003c\/p\u003e\n\u003cp\u003eA: The AAP135 module supports dual-redundant configuration. The shunt resistance is open on the standby side in a dual-redundant arrangement. The complete system configuration must follow the applicable Yokogawa installation requirements.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":69286543917298,"sku":"AAP135-S53\/K4A00","price":235.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/5589\/5794\/files\/AAP135-S53K4A002.jpg?v=1794383499","url":"https:\/\/www.petrospare.com\/products\/yokogawa-aap135-s53-k4a00-pulse-input-module","provider":"Petro Spare Industrial Limited","version":"1.0","type":"link"}
