Hardware required for network connection:

CIU 900 + CIM 280
Product number CIU 900: 99448387

For North America frequency bands
CIM 280-US 3G/4G cellular
Product number: 99895386

Note: CIM 280 contain a eUICC plastic SIM card with int. roaming and requires an 3G/4G antenna (99606613) and an external mounting bracket (99606614) or a high gain directional antenna (98851149).

Note: To use Grundfos Connect a 1 year subscription (92711156) is needed.

Option: Rechargeable lithium-ion battery (99499908) for 3G/4G mobile interfaces that allows the CIM280 to send an alarm in case of power failure.

CIM/CIU 290 communication interface for easy integration into Grundfos Connect solution.

IO 113 monitoring, protection and communication module
The IO 113 is a protection module designed specifically for Grundfos SE/SL 9-30KW and The S wastewater ranges. The IO 113 has various dedicated analogue, PT100/1000 and digital inputs to monitor the pump and has a galvanically isolated output, that can be integrated into the pump control system to stop the pump in the event of failure.
The IO 113 offers the following monitoring functions*:
• motor temperature
• moisture in motor
• Water in oil
• insulation resistance.
• Pump vibration
• Bearing temperature

    * Please ensure the pump selection incorporates the required sensors for the monitoring function required.

SM 113 sensor module
The SM 113 is an expansion unit that supports the IO113 . The SM 113 is only used in combination with the IO 113. The two devices communicate with each other via a powerline connection with the Grundfos GENIbus protocol.
Supporting the IO113 the SM 113 increases the ability of this extended system to monitor data from the following sensors:
• 3 flow sensors, 4-20 mA
• 3 PT100 temperature sensors
• 3 PT1000 temperature sensors
• 1 PTC temperature sensor
• 1 digital input.
