It receives and counts pulse signals with an input frequency range of 0 to 10 kHz. Its isolated input channels provide separation between signal channels. The module is supplied with a KS Cable Interface Adapter, model ATK4A-00, for cable interfacing.\u003c\/p\u003e\n\u003ch3\u003eFunctional Overview\u003c\/h3\u003e\n\u003cp\u003eThe AAP135 is designed to acquire pulse signals from field devices and provide pulse-count information to the control system. It supports eight input channels, allowing multiple pulse sources to be monitored through one module.\u003c\/p\u003e\n\u003cp\u003ePulse counting is used where the control system needs to process discrete signal transitions rather than continuous analog values. The specified 0 to 10 kHz input range defines the supported pulse frequency range for signal acquisition.\u003c\/p\u003e\n\u003ch3\u003eChannel Configuration and Signal Isolation\u003c\/h3\u003e\n\u003cp\u003eThe module provides eight isolated pulse input channels. Channel isolation helps separate individual input signal circuits, reducing the direct electrical interaction between channels.\u003c\/p\u003e\n\u003cp\u003eThe pulse-counting function makes the AAP135 suitable for interfacing with field instruments that provide frequency or pulse-based outputs. Actual signal compatibility should be checked against the connected instrument's electrical output characteristics.\u003c\/p\u003e\n\u003ch3\u003eOrdering Configuration\u003c\/h3\u003e\n\u003cp\u003eThe complete ordering number is AAP135-S50\/K4A00.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAAP135: 8-channel pulse input module with pulse-counting functionality and a 0 to 10 kHz input range.\u003c\/li\u003e\n\u003cli\u003e-S: Standard type.\u003c\/li\u003e\n\u003cli\u003e5: No explosion protection.\u003c\/li\u003e\n\u003cli\u003e0: Basic type.\u003c\/li\u003e\n\u003cli\u003e\/K4A00: Includes KS Cable Interface Adapter, model ATK4A-00.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe option code identifies the specified cable interface configuration.
