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-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.

	SI-PROFIBUS PROFIBUS DP interface module; Simplex Pump only.
	SI-DEVICENET DeviceNet interface module; Simplex Pump only.
	SI-CANOPEN CANopen interface module supporting various profiles, including several drive profiles; Simplex Pump only.
	SI-ETHERNET Ethernet module that supports EtherNet/IP and Modbus TCP/IP; standard for Multiplex Pump solution, optional for Simplex Pump solution.
	SI-PROFINET-V2 PROFINET RT interface module; Simplex Pump only.
	SI-ETHERCAT EtherCAT interface module; Simplex Pump only.

Keypads

Unidrive M400 AC drives do not include a keypad as standard. A CI-KEYPAD is recommended to be ordered for easy setup, diagnostics, and to load SD card files from the AI-BACKUP-ADAPTOR.

	CI-Keypad LCD Three line plain text, multi-language LCD keypad for rapid setup and helpful diagnostics maximizes machine up-time.
	Remote keypad All the features of the CI-Keypad LCD, but remote mountable. This allows flexible mounting on the outside of a panel and meets IP66 (NEMA 4)
	REMOTE-KEYPAD-RTC The keypad is remote mountable, allowing flexible mounting on the outside of a panel (meets IP54/ NEMA 12). Three line multi-language plus custom text LCD keypad for rapid setup and helpful diagnostics. Battery operated real-time clock allows accurate time stamping of events, aiding diagnostics.

Drive Pump Parameters

A pre-loaded default pump parameter SD card and adaptor can be ordered for backup pump parameters.

• AI-CTASP provides backup default Simplex Pump parameters. Includes an SD card and AI-BACKUP-ADAPTOR
• AI-CTAMP must be ordered for Multiplex pump parameters. Includes an SD memory card and AI-BACKUP-ADAPTOR with individual parameter files loaded for drives 1, 2 and 3 in a multiplex system.

Drive Interface units - Communications

	AI-485-ADAPTOR Adaptor that allows the drive to communicate via Modbus RTU over RS485.
	AI-485-24V-ADAPTOR Adaptor that allows the drive to communicate via Modbus RTU over RS485, and an input for 24 V backup.
	CI-485-ADAPTOR Adaptor that allows the drive to communicate via Modbus RTU over RS485, not compatible with CI-KEYPAD-LCD option.
	CT-USB-CABLE The USB Communications cable allows the drive to connect to a PC for use with Unidrive M's PC tools via a Modbus RTU adaptor.
