Versions K = contact F = separate, field housing

IFC 090 K/B and F/B (standard) Basic version, without local display and control elements

IFC 090 K/D and F/D (option) Display version, with local display and control elements

IFC 090 K/D-EEx Hazardous-duty version with outputs in Increased Safety

Interface (option) HART

Add-on equipment (option) CONFIG software and adapter for operator control via

MS-DOS PC, connection to internal IMoCom interface

(equipment bus)

Current output

Function – all operating data settable

– galvanically isolated from all output and input circuits

– for active or passive mode (Ex version only active)

Current: fixed ranges 0 – 20 mA and 4 – 20 mA

variable ranges for Q = 0% I

= 0 – 16 mA adjustable in 1mA

for Q = 100% I

100%

= 4 – 20 mA increments

for Q > 100% I

max

> 20 up to 22 mA maximum

Active mode max. 500 Ω load

Passive mode external voltage: 15 ... 20 V DC 20 ... 32 V DC

load: min. ... max. 0 ... 500 Ω 250 ... 750 Ω

Error identification 0 / 22 mA and variable

Forward/reverse flow measurment direction identified via status output

Pulse output

Function – all operating data settable

– galvanically isolated from current output and all input circuits

– digital pulse division, interpulse period non-uniform,

therefore if frequency and cycle meters connected

allow for minimum counting interval:

gate time, totalizer ≥

Activ mode connection: electronic totalizers

voltage: approx. 15 V DC, from current output

load: I

max

< 23 mA, operation without current output
