•It protects the MI 24 01 inputs.

•8 external transmitter supplies for two-wire transmitters S1...S8.

•Low pass filter for HART signals.

•It can be used with transmitter supply voltage monitoring.

•It can be used up to SIL 3.

•DIN rail mounting.

1.2 Operation

To operate the H 7032, set the following parameters:

•In ELOP II Factory/SILworX, set transmitter supply of the module MI 24 01

MI[xx].Transmitter Used to "FALSE".

•Set the power supply (L+) of H 7032 to the following value:

L+ = UTmin + 16 V at 23 mA, UTmin = minimum transmitter supply voltage

•Use the IMIH terminal if the filtered input signal of the two-wire transmitter should

be used.

1.2.1 Monitoring of the transmitter supply voltage UTM

To monitor the transmitter supply voltage UTM, connect the analog input of the MI 24 01

module to the SM and L- terminals. The transmitter supply voltage UTM is monitored via the

current IMI24, see the following formulas:

IMI24 = UTM / 3200 Ω

UTM = UTmin + ITx 500 Ω+ ITx Rwire+ UFuse 32 mA + Tolerance

Example:

UTmin = 12 V, IT= 22 mA, Rwire= 40 Ω, UFuse 32 mA = 0.6 V, Tolerance = 0.9 V

IMI24 = (12 V + 11 V + 0.88 V + 0.6 V + 0.9 V) / 3200 Ω

IMI24 = 7.93 mA

The input current of MI 24 01 must not fall below 7.93 mA.

The module MI 24 01 checks the transmitter supply voltage UTM. If UTM is less than the

minimum transmitter operating voltage UTmin, the signals from the connected transmitter may

no longer be classified as safe.

1.4 Mounting the H7032 in Zone 2

(EC Directive 94/9/EC, ATEX)

If the special conditions X are observed, the H 7032 device may be installed in Zone 2.

The corresponding EC declaration of conformity is available on the HIMA website.

Special Conditions X

Mount the device in an enclousure (cabinet) that meets the EN / IEC 60079-15 requirements

and achieves a type of protection of at least IP54 (category 1) in accordance to

EN / IEC 60529.

This enclosure (control cabinet) must be labelled as follows:

WARNUNG – NICHT UNTER SPANNUNG ÖFFNEN

WARNING – DO NOT OPEN WHEN ENERGIZED

Note: If a potentially explosive atmosphere has been precluded, work can be also

performed when the device is under voltage.

The enclosure (control cabinet) in use must be able to safely dissipate the generated heat.

The H 7032 device has a power dissipation of 4 W.

Since the device is equipped with exchangeable fuses, an additional warning must be placed

on the front plate of the enclosure (control cabinet). The warning should have following text:

WARNUNG – SICHERUNGEN NICHT UNTER SPANNUNG

HERAUSNEHMEN ODER WECHSELN

WARNING – DO NOT REMOVE OR REPLACE FUSES

WHEN ENERGIZED

The EC Directives and the following standards must be observed when installing and

operating the device:

DIN EN 60079-15 (VDE 0170/0171 Part 16)

DIN EN 60079-0 (VDE0170-1)

DIN EN 60079-11 (VDE0170-7)

DIN EN 60079-14 (VDE 0165 Part 1)

The H 7032 device is labelled with the following special product marking:

µII 3 G Ex nA II T4 X 0°C ≤Ta ≤60°C

Special conditions X must be regarded!
