The frequency transducer/pulse counter

IMX12-FI01-1SF-1I1R-C0/24VDC is equipped

with intrinsically safe input circuits and transmits frequency signals up to 20,000 Hz electrically isolated from the at-risk area to the

safe area. In addition, limits, slip or clockwise/counter-clockwise rotation can be monitored. The devices are suitable for operation

in zone 2.

The 1-channel device is equipped with two

intrinsically safe inputs for the connection of

sensors acc. to EN 60947-5-6 (NAMUR). On

the output side, there is a 0/4…20 mA current

output and a normally open relay.

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

SIL 2 (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.
