Precision binary inputs

The precision binary inputs are used for accurate detection of status changes of main or auxiliary
contacts in the circuit breaker.
Connectors are delivered with the device. Each connector terminal is connected with one 0.5...2.5
mm² (AWG 20...13) wire or with two 0.5...1.0 mm² (AWG 20...17) wires.

Binary inputs for spring charge level are intended for circuit breakers in which the
drive energy and the operating capability can differ with the position of the main
storage element (spring). This occurs in spring-hydraulic drives such as Hitachi
Energy models HMB/HMC. The spring charge information is used for compensation
of operating times and for reporting the CB's operating capability. However, if the
breaker is not used for fast reclosing and if the spring is always fully charged prior to
each operation, these inputs need not be connected. Similarly, these inputs are not
used with drives in which the spring is always fully charged by design.
