| Introduction | Data sheets | Certificates |
The frequency transmitter allows to monitors the speed of rotating devices like fans, centrifuges, tube extruder, etc. in the harzardous area. The detected input frequency is processed in different ways:
- relay output with configurable set points
- conversions into an proportional 0/4 mA ... 20 mA analogue signal
- impuls output with optional frequency divider function
The optional start-up delay allows to start a system without creating accidental alarms. The frequency transmitter can be easily configured by the ISpac Wizard.
