Supporting Terminals
Do not use the unused terminals (terminals 2, 6, 10, 14,19, 23, 27, 31, 36, 37, 38,
39, 46, 47, 48, 49) on this terminal base unit. Using these terminals as supporting
terminals can result in damage to the module and/or unintended operation of your
system. (see Figure 4)
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 (). The maxi-
mum intrinsically safe values must not be exceeded.
Figure 4
Installation
This module must not be exposed to the environment. Provide a separate enclo-
sure with a protection factor of at least IP54. This module must be installed in such
a way that protection factor IP20 is guaranteed. Do not remove the Cover plug on
the right-most terminal base unit.
Safe area mounting
The module cannot 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 factory.
ESD
Protect the system against electrostatic charge. Post a sign near this module: At-
tention! Avoid electrostatic charge.

Outputs
Each output can operate an I/P Converter in the current range 0-22 mA. Every
other binary or analogue actuators is possible, which do not exceed the allowed
Ex-values of the module.
When using an intrinsically safe electrical apparatus according to EN50020, the
European Community directives and regulations must be followed.
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.
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 tempe-
rature 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 7) 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 7) 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
