The frequency transducer/pulse counter IM12-

FI01-1SF-1I1R-CPR/24VDC transmits frequency signals up to 20000 Hz electrically

isolated. In addition, limits, slip or forward/reverse run can be monitored. The devices are

suitable for operation in zone 2.

The 1-channel device is equipped with two

inputs for the connection of sensors acc. to

EN 60947-5-6 (NAMUR) or potential-free contacts. A current output (0/4…20 mA) and an

NO relay are available on the output side. The

device can be powered from a power bridge

that also transmits a collective fault signal.

The device is parameterized via FDT and

IODD with a PC. The current output can be

set to 0/4…20 mA (source or sink optional). In

accordance with the parameterization (E1, E2,

E1-E2 or E2-E1), the input signals are provided as a 0/4…20 mA standard current signal.

With the NO relay, either a limit value can be

monitored on over/undershoot or a window.

The start-up delay SUD is turned on via input

E1, E2 or E3.

The devices have a green power LED (Pwr)

and a red LED to indicate internal faults. For

the input circuit there is a yellow and red status LED available. A fault in the input circuit

leads to a flashing red LED according to NE44

and an internal fault to a steady read LED.

The fault current can be adjusted to < 3.5

mA or > 21.5 mA. A yellow LED indicates the

switching state of the limit value relay. A yellow LED indicates that the start-up delay is

turned on.

The device can be used in safety circuits up

to SIL2 (high and low demand according to

IEC 61508) and meets the requirements of

the NE21. It is equipped with removable screw

terminals.
