- In the control technology of today, the number of industrial PCs (IPC) partly with decentralized intelligence constantly increases.
- Individual processes are controlled independent of each other. In case of failure or malfunction of one component, it can therefore be necessary to switch off the hardware of a complete machine or plant.
- Time-Relay WD100V is used to make sure that because of malfunctions in the program flow, caused by short-term voltage interruptions for instance, no undefined status are created.
- Input-signal 5/24 V DC square wave
- Minimum pulse length 500 μs
- Maximum pulse length 10 s
- Monitoring of positive and negative slopes
- Watchdog-time = Time x Scale (1 ms-10 s)
- Display of state of function with LED (Alarm)
- Reset with external contact or switch
- Universal power-supply AC/DC 24-240 V
- Relay-output (1 change-over contact)
