The frequency transducer/pulse counter

IMX12-FI01-2SF-2I-CPR/24VDC is equipped

with intrinsically safe input circuits and transmits frequency signals up to 20,000 Hz from

the Ex area to the non-Ex area such that the

signals are galvanically isolated. In addition,

the input signals can be monitored for slip.

The devices are suitable for operation in zone

2.

Each channel of the 2-channel device is

equipped with an intrinsically safe input for

connecting sensors in accordance with EN

60947-5-6 (NAMUR) or potential-free contacts. On the output side, a current output 0/4

… 20 mA is available for each channel. 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.

The devices have a green power LED (Pwr)

and a red LED to indicate internal faults. For

each input circuit there is a yellow and a red

status LED. A fault in the input circuit leads

to a flashing red LED according to NE44, an

internal fault to a steady read LED. The fault

current can be adjusted to 21.5

mA.

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.

The device is equipped with removable screw

terminals.
