Type WD100V, Watchdog Time-Relay for industrial PCs (IPC) - (Ordering Code Z224319)
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.
Overview of features:
• 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)
