2 Product Specifications
2.1 Function
Isolated barriers are used to protect intrinsically safe circuits in explosive areas. In
addition to the required current and voltage 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 H-System termination board with isolated barriers for HIMA
Universal 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 System Components
2.2.1 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 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.

2.2.2 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.

• For HiC or HiD isolated barriers
• With 16 or 32 slots
• For redundant and fused power supply

Label carriers for Termination Boards
The termination boards can be fitted with a label carrier for individual
identification.

HART Communication Board
The HART Communication Board is connected to HART-compatible H-System
termination boards. It has one slot to mount a 32-channel HiD Mux2700-type
HART multiplexer.
Preconfigured HART connection cables enable easy connection between the
H-System termination boards and the HART Communication Board.
The device offers a redundant fused power supply with an LED indicator. The
RS 485 terminals have a redundant configuration and enable simple bridging to
the next bus node.

2.3 Connection Options
A variety of termination boards is available with different methods of connecting to
the field and control side. Please refer to the documentation for the respective
device for the specific connection layout.
Connecting the Field Side
The field devices can be connected to the termination board via spring terminals:
Figure 2.8 Connection via spring terminals
Connecting the Power Supply and Fault Indication Output
Isolated Barriers
The isolated barriers are supplied via the termination board. The isolated barriers
are therefore attached to the termination board.
Termination Boards
The termination boards are supplied with power via spring terminals in
accordance with their design.
The supply voltage range depends on
• The values used for the isolated barriers
• The voltage drop of the decoupling diodes on the termination board
