The frequency transducer IM12-

FI01-1SF-1R-0/24VDC transmits frequency

signals up to 20,000 Hz galvanically isolated.

This device is used for monitoring limit values.

The device is suitable for use in Zone 2.

The one-channel device is equipped with two

inputs for the connection of sensors acc. to

EN 60947-5-6 (NAMUR) or potential-free contacts. A 3-wire input and a pulse input are also

available. A changeover relay is available on

the output side.

The device is parameterized via rotary coding switches and DIP switches on the side of

the device. The relay output is used to monitor

whether a limit value exceeds or undershoots

a limit value or lies outside a limit value window. Depending on the parameter, the startup delay (SUD) is activated via input E2 or E3.

The devices have a green and a red Power

LED (Pwr) for indicating the operating voltage

and the parameterization. For each input circuit there is a yellow and a red status LED. An

error in the input circuit causes the red LED

to flash according to NE44. A yellow LED indicates the switch-on delay. A red and a yellow LED are available to indicate the switching status of the relay.

The device can be used in safety circuits up to

SIL2 (high and low demand according to IEC

61508) and meets the requirements of NE21.

It is equipped with removable screw terminals.

The device is equipped with removable screw

terminals.
