SDV FH6 Voltage Sensor / Monitoring Relay – Complete Description
The SDV FH6 Voltage Sensor and Monitoring Relay is a reliable and compact protection device designed to continuously monitor electrical voltage conditions and safeguard connected equipment from abnormal power situations.
This device monitors under-voltage, over-voltage, phase failure, and voltage imbalance (depending on application configuration). When the voltage exceeds preset safe limits, the SDV FH6 instantly responds by activating or deactivating its relay output. This fast reaction helps prevent damage to sensitive electrical loads such as motors, compressors, control panels, automation systems, and power supplies.
G9B-12 STEPPING RELAY Product Description
Input and Output
- Input: The unit utilizes Step signals and Reset inputs. Upon receiving an input pulse, the relay switches to the next step. When a Reset input is triggered, it immediately returns to the starting position (Terminal 1).
- Output: The G9B-12 model provides 12 stepping contacts and 1 alarm contact. Each contact is capable of switching loads up to 2 A at 250 VAC or 30 VDC.
- Pump Control: To manage the sequential operation of multiple pumps.
- Process Control: In complex industrial processes that require a specific sequence of actions.
- Production Lines: Controlling various stages within automated manufacturing systems.
- Safety Systems: It includes an internal malfunction detection feature that identifies mechanical or electronic errors and triggers an alarm, ensuring system safety.
