REM-4 Relay Expansion Module

Ensure healthy livestock and maximum profits with tighter control of water quality and system parameters. The YSI IOEM and REM expansion modules increase the flexibility and capability of the YSI aquaculture platform when networked with 5200A, 5400 or 5500D instruments.

• Overview

  REMs (Relay Expansion Module) add relays where needed to control feeders, lighting, heaters, alarming, and more.

  • 4 user-configurable output relays
  • Plug-and-play: easy to install, setup and maintain (no need to hire programmers or engineers)
  • NEMA 4X (IP-66)
  • AC and DC power (DC power can be used for battery back-up if used with AC power) 
  • 2-year warranty

  Building a system is easy. Choose the expansion module appropriate for your needs (control, communications, etc.) and network with a 5200A, 5400 and/or 5500D with AquaManager®. Configure 4 (IOEM-4) or 8 (IOEM-8) analog channels as inputs or outputs for the ability to integrate 3rd party sensors or output from other devices. Outputs can be configured to control pumps, UV systems, analog valves, or send data to SCADA/ PLC systems. 

  Applications:

  • Recirculating systems
