Description

Product Overview

The ABB IMDSM04 is a versatile Pulse Input Slave Module designed for the Infi 90 Process Management System. It enables the integration of up to eight independent pulse or frequency signals from field devices into the control system, supporting applications such as turbine flowmeters, tachometers, Wattmeters, proximity sensors, and counters.

Key Features

• Eight Independent Inputs: Supports pulse/frequency signals with optical isolation

• Voltage Ranges:

  • 4–6 VDC

  • 21.6–27 VDC (dry contact compatible)

  • 50 mV–10 V peak-to-peak (channels 1 & 2 via preamplifiers)

• Signal Processing: Converts analog pulses to digital for system integration

• Configurable Inputs: Jumper-selectable voltage and response time (fast/slow)

• High Resolution: 16-bit input resolution for frequencies up to 50 kHz

• Precision Timing: Measures pulse intervals from 20 µs to 655,000 seconds

• Edge Detection: Counts rising/falling edges and measures time between pulses

• System Integration: Seamlessly connects to Infi 90 and Network 90 controllers

• Modular Design: Flexible configuration for diverse process strategies
