1.1. Product description
The iQdata monitoring units RMS 222, RMS 442 and RMS 842+ are the main modules for environmental
monitoring. The RMS 842+ is used to monitor and log larger infrastructures in different buildings, while the RMS
222 and RMS 442 are used for small systems.
The main monitoring systems cannot be interconnected. In order to increase the number of sensors and devices,
extension units such as the extension unit, 64DI unit and CAN sensors can be used instead. Each monitoring unit
has an integrated software interface and can be connected via an IP address.
