ComAp – InteliAIN8

Description

The Inteli AIN8 is an extension module developed by ComAp to augment the analog input capabilities of compatible controllers, such as InteliSys NT, InteliGen NT, InteliMains NT, and InteliDrive DCU. This module provides additional analog input channels and an impulse/RPM input, facilitating comprehensive monitoring and control of various parameters.

Key Functions:

• Analog Input Channels: Offers eight configurable analog input channels that support various sensor types, including:
  • Resistor 3-wire inputs: Compatible with resistors ranging from 0-250Ω, 0-2400Ω, to 0-10kΩ, and temperature sensors like Pt100, Pt1000, Ni100, and Ni1000.
  • Current inputs: Accommodates active or passive sensors with ranges of ±20mA, 0-20mA, and 4-20mA.
  • Voltage inputs: Supports voltage measurements of ±1V, 0-2.4V, 0-5V, and 0-10V, including compatibility with lambda probes.
• Impulse/RPM Input: Includes an input capable of measuring RPM pulses with frequencies ranging from 4Hz to 10kHz, allowing for accurate monitoring of engine speed or processing pulses from devices like electrometers and flowmeters.

Applications:

• Enhanced Monitoring: Expands the monitoring capabilities of compatible controllers by providing additional analog inputs for various sensors, enabling detailed supervision of engine parameters, environmental conditions, or system performance metrics.
• Engine Speed Measurement: Utilizes the impulse/RPM input to accurately measure engine speed, essential for applications requiring precise RPM monitoring and control.
• Resource Consumption Tracking: Processes pulses from devices such as electrometers and flowmeters, facilitating the measurement of total consumption and average fuel consumption, which is vital for optimizing operational efficiency and resource management.

By integrating the Inteli AIN8 module, users can significantly enhance the data acquisition and monitoring capabilities of their control systems, leading to improved operational oversight and efficiency.

To expand the capabilities of your ComAp controllers, I/O extension modules are essential. They allow you to monitor more sensors (temperature, pressure, fuel levels) and control more auxiliary equipment than the base controller allows.

The modules are generally divided into two “ecosystems”: the Inteli (Standard/Newer) and the IS/IGS (Legacy/High-End).

Comparison of I/O Extension Modules

Key Module Breakdowns

1. The “Standard” Range (Inteli AIN8 / AIN8TC / AIO9/1)

These are the workhorses for standard industrial applications.

• Inteli AIN8: Used for common sensors like oil pressure or coolant temperature. It also features an RPM input, which is critical if your engine doesn’t have an ECU.

• Inteli AIN8TC: Specifically for Exhaust Gas Temperatures (EGT) or cylinder head temps where thermocouples are required.

• Inteli AIO9/1: A “problem solver” module. With 9 inputs and 1 output, it’s often used in CHP applications to control a valve based on multiple temperature readings.

2. The “Sys” Range (IS-AIN8 / IS-AIN8TC / IS-BIN16/8)

The IS prefix stands for InteliSys. These were designed for the high-end NTC BaseBox controllers.

• Application: Used in massive power plants and data centers.

• Complexity: They offer higher galvanic isolation and precision, designed to survive the electrical “noise” of heavy switchgear.

• Successor Note: While these still work with older systems, the InteliGen 1000 era favors the newer Inteli IO family, which is faster and easier to configure via InteliConfig.

3. The “Output” Specialists (I-AOUT8 / IS-BIN16/8)

• I-AOUT8: Mostly used to drive old-school analog “needle” gauges on a control panel or to send signals to a third-party Building Management System (BMS).

• IS-BIN16/8: This is a “Binary Beast.” It provides a massive amount of digital inputs and outputs, perfect for controlling complex breakers, fans, and pumps via the controller’s internal PLC.

Summary: Legacy vs. Modern

If you are building a new system with an InteliGen 4 200 or InteliGen 1000, you should prioritize the Inteli IO series (like the Inteli IO8/8). These newer modules are “plug-and-configure,” whereas the older IS and IGS modules sometimes require manual address mapping in the older GenConfig software.
