Simplex and Multiplex Pump Control

0.33 hp – 200 hp (0.25 kW – 132 kW) Simplex Pump
0.5 hp – 200 hp (0.37 kW – 132 kW) Multiplex Pump

115 V | 208 - 240 V | 380 - 480 V | 575 V | 690 V

The Control Techniques Unidrive M400 Pumping Solutions are a cost effective and versatile variable speed control system for maintaining energy efficient, constant water pressure in single-phase (0.33 - 50 hp) or 3-phase (0.5 - 200 hp) applications. These single-pump and multi-pump (up to 3 max) configurations utilize the onboard controller on the Unidrive M400 variable frequency AC drive (VFD) for economical and easy to use control.

Based on the highly reliable Unidrive M400 AC drive, these solutions provide programming dedicated to simplex and multiplex pump operation. The AI-CTASP (Simplex Pump) and AI-CTAMP (Multiplex Pump) options include an AI-BACKUP-ADAPTOR with SD memory card pre-loaded with default pump parameters to make application setup easy.

Additionally, an optional HMI (human machine interface) is available that makes setup and diagnostics easy and provides additional features such as remote web access and email alerts.
 
 

SI option modules for Unidrive M400 Simplex Pump Solution (only 1 SI option module permitted per drive frame 2 and above)

SI-I/O option module for extended I/O (simplex pump solution only)
SI-IO-system-integration-option-module
SI-I/O

Extended I/O interface module to increase the number of I/O points on a drive. Provides additional: 4 x Digital I/O, 3 x Analog inputs (default) / digital inputs, 1 x Digital input, 2 x Relays

An SI-I/O option module can be ordered with Unidrive M400 simplex pump drives frames 2 and above. This module provides control over additional pump application parameters.

Additional features include:

  • Multiple set-point selection
  • Over temperature switch input
  • Trip reset input
  • An additional user programmable relay

 SI communications modules (frame size 2 and above)

A variety of SI communications modules can be ordered to add further flexibility to your simplex pump application. The Unidrive M400 Multiplex Pumping solution includes an SI-ETHERNET module as standard. No other SI option modules can be used with the Multiplex Pump solution.
