YSI IOEM Input, Output Expansion Module

• 4 (IOEM-4) or 8 (IOEM-8) user-configurable channels as inputs or outputs
• Optically isolated to eliminate electrical interferences and ground loops
• When configured as outputs (4-20 mA) either set point or PID control can be used
• 4-20 mA outputs can interface to a SCADA or PLC system
• Inputs can be used for temperature, analog (0 to 1.0 VDC, 0 to 5.0 VDC or 4-20 mA) or digital*
• 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

* user-configurable inputs can be used for additional sensors like DO, pH, Total Gas Pressure, ORP, photo period, etc. Some sensors require an additional transmitter.

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