• System monitoring is designed keeping in mind complex control systems in a large processing unit where number of such relays are high number, need to be monitored to detect the faults and control the process. The new design is built to sense the faults &to ease monitoring of the relay or the overall function of the system electronically.
• The harsh electrical environment is the cause of failures at the controller and load(field) side. The conventional relays without the sensing functions tend to fail due to over voltage/current and any other errors. In order to overcome such failures a relay which is unique in function is designed with sensing capabilities.
• Relays generally fail as short /open circuit may be in the i/p or o/p circuit. Probability of relay failing as short is very high compared to open circuit failures. Rarely the output open circuits, but still such fault is not ruled out . It may be due to insufficient trigger to the device or the device or open path in the output circuit. In order to make the relay safe and fail proof, the voltage and current are sensed and faults are indicated to alert and monitor the processes.
• This new design is available in the hockey puck style package and rated for 25/40/50 Amps at 240 Vac. Unique SSR IN 17.5 mm built in DIN clip.
• Normally SSRs require an external heat sink beyond 5 Amperes. But this unique design manages the thermal conditions in such a way that it does not require an external heat sink even at 10 Amperes. The product can handle 10 A AC and 15 A dc currents. Mounting is DIN rail compatible and due to its slim style, more relays can be packed in the control panel.
