This Finder Override and Status indicating module is frrom the 19 Series. This relay is also known as intervention module. With the use of carefully installed intervention modules, a trained caretaker or security guard can be in a position to recognise any interruptions in service and by manual intervention perform the necessary override actions to maintain system operation until a repair can be effected.
The Auto-Off-On output module (Type 19.21) is used in the event of an electronic system malfunction it is important, in order to avoid damage or downtime, to plan for the possibility of controlling the process manually. An Auto-Off-On Module can provide this, located between the output of the electronic system (Controller) and the process to be controlled (End Process) and bypassing the malfunctioning control unit in a planned way. The relay is DIN Rail mountable.
