Our vast range of specialised temperature controllers and process indicators offer exceptional versatility due to the wide selection of sensor input options, functions and hardware configuration.
Input type, alarm types and the function of the keys on the faceplate are software selectable.
Solid State Relays
Solid state switching devices are used in most modern automation systems to switch electrical loads. They offer high durability where a high number of switching operations or a fast switching speed is required.
Further benefits are resistance to mechanical shock or vibration, moisture and dust as well as silent operation, maintenance free service and reduction of electromagnetic noise.
Switching is initiated by applying a low DC signal (typically 4-32VDC, 4mA) to the trigger input, placing less demand on control outputs and enhancing safety.
SSRs are normally “zero crossover switching“, only closing or opening when the AC power sine wave crosses zero. This eliminates electromagnetic interference and harmonics on the power supply.
