857-531 Limit value switch, analogue ON and changer OFF

JUMPFLEX® measuring transducer Limit value switch with analogue input and changer relay output

Brief description: The limit value switch for analogue signals is used to monitor analogue standard signals and to report signal states that exceed the preset threshold. The device has an analogue input and changer relay in the output. The supply voltage for the device is 24 V DC (nominal voltage). A digital output (DO) for signalling other states, such as a range being exceeded or not being met, is also implemented. The limit value switch is adjusted via DIP switches; a "teach-in" function is also offered by means of slide switches. It is also possible to configure the device using the FDT/DTM configuration software.
