H-System – Isolated Barriers and Termination Boards
Product Specifications
2 Product Specifications
2.1 Function
Isolated barriers are used to protect intrinsically safe circuits in explosive areas. In addition
to the required current, voltage and power limitation, the isolated barriers have a galvanic
isolation between the field circuit and the controller.
The H-System isolated barriers are mounted on termination boards. Pre-wiring is possible on
termination boards. To close the signal circuit, the isolated barriers are simply plugged in.
The isolated barriers can be replaced during live operation when the wiring is connected.
Figure 2.1 Generic H-System termination board with isolated barriers
Generic and control system-specific termination boards are available in the H-System.
Termination boards can be adapted to specific input/output requirements. These requirements
can be implemented via
• Various connecting plugs to the controller
• Various terminals to the field device
• A large selection of isolated barriers

2.2 Isolated Barriers
H-System isolated barriers are available in two different housing widths depending on
the function and application:
• HiC devices with a width of 12.5 mm
• HiD devices with a width of 18 mm
Both versions cover all functions and the interoperability of the H-System.
The pin assignment and terminal designations are consistent for all termination boards.
Each H-System isolated barrier can therefore be mounted in each termination board slot.
• HiC isolated barriers on HiC termination boards
• HiD isolated barriers on HiD termination boards
The termination board can be coded together with the isolated barriers. This prevents
the isolated barriers being mixed up on the termination board. The safety-relevant data for
the connected field devices is backed up.

2.3 Termination Boards
Termination boards form the wiring level for field and control signals. The isolated barriers
are mounted on termination boards. The isolated barriers are connected with the field and
control side via the termination boards. Once the isolated barrier is mounted, the signal circuit
between the field and control side is closed.

3 Mounting and Installation
3.1 Termination Board Mounting
Danger!
Explosion hazard from damaged electronic components
Premature wear of electronic components in a device that was previously used in a general
electrical installation can cause sparks that can ignite the surrounding potentially explosive
atmosphere.
Never install devices that have already been operated in general electrical installations in
electrical installations used in combination with hazardous areas!
Danger!
Explosion hazard from pollution
An excessively polluted surface of the device can become conductive and consequently
ignite a surrounding potentially explosive atmosphere.
Ensure that you install the device only in environments with a pollution degree 2 or better
according to IEC/EN 60664–1.
Warning!
Risk of short circuit
Working on live parts can cause injuries and can compromise the function and the electrical
safety of the device.
• Before working on the device, always disconnect the supply voltage.
• Connect the device to the supply voltage only after completion of the work.
