AAP135-S00/K4A00 Yokogawa Pulse Input Module 8-Ch

Yokogawa AAP135-S00/K4A00 Pulse Input Module

• Brand & Model: Yokogawa, AAP135-S00/K4A00 (Pulse Input Module, 8-channel, 0 to 10 kHz, Isolated Channels).
• Input Channels: 8 isolated channels, supports 2-wire (contact, voltage, current) and 3-wire (power-supply-type voltage) signals.
• Frequency & Pulse Width: Input frequency from 0 to 10 kHz, with a minimum pulse width of 40 µs.
• Signal Levels: Contact input – open at ≥100 kΩ, close at ≤200 Ω. Voltage/current pulse – VH: 3 to 24 V DC, VL: -1 to 8 V DC, swing ≥3 V.
• Shunt & Pull-up: Selectable shunt resistance (none/200/500/1000 Ω) and a fixed 68 kΩ pull-up resistor (12 V or 24 V DC).
• Transmitter Power: Provides 12 V DC (±10%, 40 mA) or 24 V DC (±10%, 30 mA) for field transmitters.
• Data Update: Fast 2 ms data update period for real-time counting applications.
• Withstanding Voltage: 500 V AC for 1 minute between input and system, and between channels.
• Filter & Redundancy: Programmable chattering filter; supports dual-redundant configuration for high availability.
• Power Consumption: 300 mA (5 V DC) and 400 mA (24 V DC). Weight: 0.3 kg.

Technical Specifications in Detail

• Input Signal Types: Contact ON/OFF, voltage pulse (3–24 V DC), current pulse (converted to voltage).
• Signal Source Resistance: Must be 1 kΩ or less for accurate measurement.
• Shunt Resistance Selection: Choose none, 200 Ω, 500 Ω, or 1000 Ω per channel (open when power OFF or standby).
• Contact Capacity: At 12 V DC – 15 V DC / 15 mA; at 24 V DC – 30 V DC / 30 mA.
• Environmental Tolerance: Designed for industrial environments with robust isolation and noise rejection.
• External Connections: Pressure clamp terminal, KS cable, or MIL connector cable (option /K4A00 includes KS Cable Interface Adapter ATK4A-00).

Installation & Mounting Guidance

• Mount the AAP135-S00/K4A00 in a standard Yokogawa I/O rack with adequate ventilation.
• Use the provided pressure clamp terminal or KS cable for secure field wiring.
• Set the shunt resistor and filter parameters via the system configuration software before operation.
• For dual-redundant setups, install two modules and connect them to the same field signals.
• Ensure the power supply matches the module’s requirements (5 V DC and 24 V DC).
