The CMS-200xx Series Circuit Monitoring System (CMS) Sensors from ABB Electrification Products are designed for comprehensive energy monitoring and performance measurement of branch circuits. These sensors are compact, measuring only 17.5 mm or 25 mm in width, making them suitable for installations where space is limited. They can monitor AC or DC currents up to 160 A TRMS and support configurations for mixed currents. The system allows for the monitoring of up to 96 sensors through a single control unit, which can be easily integrated into existing setups or used in new designs. Installation is straightforward, with options for direct mounting on devices, DIN rail, or cable connections. The sensors feature a digital transmission of measurement data via the CMS-bus interface, enhancing data integrity and reducing wiring complexity. Measurement accuracy for AC is within ¬±0.5% and for DC ranges from ¬±0.7% to ¬±1.7%, depending on the specific sensor type. The sensors operate effectively in a temperature range of -25¬8C to +70¬8C and comply with IEC 61010-1 and UL 508 standards. Data extraction is facilitated through Ethernet or Modbus RTU, ensuring compatibility with various systems without the need for specialized software.
CMS sensors
Small size, huge performance
No space wasted here: everything is built into an 18 or 25 mm wide unit to enable exact and effective measurements. This means that CMS sensors are among the most compact and high-performance current sensors on the market.
Whether AC, DC or mixed current, CMS sensors measure all types of current up to 160 A (TRMS). Even upper sidebands in the signal trace are captured.
Every sensor has its own signal microprocessor, meaning measurement data is transmitted digitally via the CMS-bus interface to the control unit. This reduces the number of cables into the distribution units and maximizes the security of the transmitted measurement values. Disruptions like those for analogue data are finally a thing of the past.
