Frequently Asked Questions (FAQ)

Q1: What is the difference between high-speed and basic cycles?

The Yokogawa AGP813-S10 runs high-speed cycle at 5 ms. Basic cycle runs at 10 ms. High-speed channels are for critical protection functions. Basic channels are for monitoring and less critical signals.

Q2: How many analog inputs does this module have?

This module has 10 analog inputs total. Four channels run at high-speed cycle (5 ms). Six channels run at basic cycle (10 ms). All inputs accept 1 to 5V signals with ±4 mV accuracy.

Q3: What is the maximum output current per channel?

Each output channel handles up to 100 mA at 30 V DC. Output type is current sinking. Maximum ON voltage drop is 0.3 V DC. ON/OFF delay is 1 ms typical.

Q4: What cables work with the AGP813-S10?

Use dedicated Yokogawa cables AKB337-M005, M007, or M010. These cables provide proper shielding and pin configuration. Standard MIL cables may not work correctly.

Q5: Is this module suitable for gas turbine protection?

Yes, this module is designed for turbomachinery protection. High-speed cycle at 5 ms supports overspeed and vibration protection. Isolated channels provide safety and reliability for critical turbines.

Buying Guide

When you buy a Yokogawa AGP813-S10 turbomachinery module, follow these tips. First, count your protection channels. You get 4 high-speed analog, 6 basic analog, 4 high-speed digital input, 8 basic digital input, and 12 digital outputs. Second, verify your scan speed needs. Use 5 ms cycle for critical protection. Third, check your signal types. Analog inputs accept 1-5V only. Fourth, confirm your output load. Each output handles 100 mA maximum. Fifth, calculate your power budget. The module draws 900 mA at 5V DC. Sixth, order the correct cables. You need AKB337-M005, M007, or M010. Seventh, plan your isolation strategy. This module provides 500V AC isolation. Eighth, review warranty terms. We offer 12 months coverage. Ninth, choose your shipping method. We use FedEx, UPS, and DHL. Finally, test the module with a simulation tool before connecting to live machinery.
