Electronic relays Neither overload nor underload are particularly good for machines and installations in industrial applications. An unsteady power supply may lead to machine failure and, thus, expensive downtimes. Consequently, electrical parameters such as voltage, current, phases, power factor (cos ϕ) and filling levels of conductive fluids should be monitored carefully and professionally. Series C x electronic monitoring relays from ABB are versatile. This extensive range offers various relays for detection and monitoring of electrical parameters such as current, voltage, phase imbalance, phase failure and phase sequence in single-phase or three-phase power systems and filling levels of conductive fluids. Thus, relays C 0 to C make it just as easy to protect installations and machines against overvoltage and undervoltage as they do to monitor currents in AC or DC power systems. Relays C 6 monitor overvoltage and undervoltage in -phase power systems with and without neutral conductor while units C and C 7 monitor phase failure, phase sequence and phase imbalance. Relay C 9 for power monitoring (cos ϕ) is used for control tasks on machines and to protect the machines against underload or overload. Level monitor C detects fluid levels of conductive fluids and can be converted to detection of falling or rising levels. Status LEDs indicate the circuit states of the units. Signalling is performed by one or two changeover contacts as an output protective circuit. All C x monitoring relays can be mounted quickly and in space-saving manner. With their overall width of 7.,. or mm, they offer performance and reliability while requiring minimum space. The ergonomic design of the operating controls allows easy and precise setting and the design and coloration of the monitoring units of Series C x match those of the entire range of ABB switchgear devices. The relays are mounted either on a mm DIN rail by snapping them on or with screws on a mounting plate. All units of the C x Series are rugged and designed for use in rough industrial atmospheres. The UL and CSA approvals permit worldwide use and all relays bear the CE mark. ABB Control Inc.. 8//00 Proof AC 0 9/00
