Power Supply

The modules are powered via the Terminal Base (terminals 34+, 35-); via the ter-

minals 50+ and 51 it is possible to daisy chain to the next module (See Figure 4).

The maximum intrinsically safe values must not be exceeded.

Figure 4

Installation

This module must not be exposed directly to the environment. Provide a separate

enclosure with a protection factor of at least IP54; the IS-RPI modules themselves

have a protection factor of IP20. Do not remove the Cover plug on the open side

of the backplane bus connection.

Safe area mounting

The module must not be used in an intrinsically safe environment after it has been

exposed to non-intrinsically safe signals.

Repair

This module is not field-repairable. Any attempt to open this module will void the

warranty and IS certification. If repair is necessary, return this module to the fac-

tory.

ESD

Protect the IS-RPI modules against electrostatic charge. Post a sign near this

module: Attention! Avoid electrostatic charge.

Subject to reasonable modifications due to technical advances

Outputs

Each output can operate to an intrinsically safe valve in the current range

0-45 mA. Other actuators are possible, which do not exceed the allowed Ex-val-

ues of the module. Do not apply any non-intrinsically safe signals to this module.

The channels in this module are electrically connected to each other and have a

common plus-line.

Important: When interconnecting several lines, you must consider the total accu-

mulated power and check for intrinsic safety.

Electromagnetic Compatibility

To achieve the EMC protection class it is necessary to use shielded multicore ca-

ble.

Ambient Temperature

The Ambient Temperature of the module (-20 °C...+70 °C) has to be considered,

especially when the modules are mounted in a cabinet where the internal temper-

ature is increased by the power dissipation of the modules itself.

If the intrinsically safe electrical circuits are led into areas with inflammable dust

the following requirements have to be fulfilled.

Zone 20

The intrinsically safe electrical circuits (Ch 0 to Ch 3) may be led into areas with

inflammable dust (Zone 20). It has to be guaranteed, however, that the devices,

to which these intrinsically safe electrical circuits are connected, fulfil the require-

ments for category 1D and are marked accordingly. All other intrinsically safe

electrical circuits may not be led into Zone 20.

Zone 21

All other intrinsically safe electrical circuits may also be led into areas with inflam-

mable dust (Zone 21). It has to be guaranteed, however, that the devices, to which

these intrinsically safe electrical circuits are connected, fulfil the requirements for

category 2D and are marked accordingly. Of course, the intrinsically safe electri-

cal circuits (Ch 0 to Ch 3) may under the same conditions also be led into Zone 21.

Zone 22

When the module is installed in Zone 22 the following cabinets have to be used:

IVK-ISRPI-V16LC

IVK-ISRPI-V8HYW

IVK-ISRPI-V8LC
