Abstract (en)
[origin: EP0720193A1] The opening/closing device includes two relays (3,4) which are controlled by respective closure and opening control circuits. Each of these circuits consists of a full-wave rectifier (e.g. 19a), a voltage regulator (20a), an optoelectronic coupler (21a) and a relay control circuit (22a) which enables closure and opening commands to be memorised. These commands apply voltages (U2,U3) of any magnitude to the inputs (8,9) of the closure and opening control circuits and an opening command (CO) also applies an inhibiting signal (I) to the closure control circuit. The equipment may also include a power supply circuit enabling a standard motor to drive the switch or circuit-breaker contacts or to set and release the spring of an energy storage device.
