The Switch Module is designed for switching DC equipment with high currents. It is controlled via an external, potential-free contact (thermostat or hygrostat) connected between terminals 1 and 2. For switching the Module, the internally generated signal current has to be used. It must ne ensured that the external contact can safely switch this signal current. The NT 73 is available in 24VDC and 48VDC versions.
