Description
Control and power section electrically isolated by opto-couplers. The control signal range is compatible with the JUMO controller logic outputs. The power section operates as a zero voltage switch, i.e. switching always takes place at zero voltage, independent of the time when the control signal changes. This avoids noise or interference voltage. A varistor is internally integrated on the output side to protect against voltage peaks. The input status is displayed by an LED.
