Operating Instructions
Binary input 4-, 6-, 8- channel

1. System information

This unit is a product of the instabus-EIB-System and corresponds to the
EIBA Guidelines. Detailed technical knowledge acquired in instabus
training courses is a prerequisite for the understanding of the system.

The functions of the device are software-dependent. Detailed information
on the software and the functions implemented and the software itself are
available from the manufacturer’s product data bank.

Planning, installation and commissionning of the device are effected with
the help of EIBA-certified software.

For the productdatabase and technical descriptions please refer to the
internet at www.jung.de offering up-to-date information..

2. Function

The binary inputs can detect the presence and the change of signal
voltages at their signal inputs.

Binary inputs can therefore be used to request the status of conventional
pushbuttons/switches, auxiliary contacts, door and window contacts and ­depending on programmed parameters - to transmit the switching status
as digital information to the instabus EIB.

The inputs can be used independent of each other. Each input is
equipped with an LED indicating the status of the contact connected.

Signal voltages can be applied to all inputs at the same time (100% duty
cycle).

The signal voltages of 24 V AC/DC or 230 V AC to be supervised must
be available externally.

3. Safety instructions

Attention: Electrical equipment must be installed and fitted by
qualified electricians only.

Non-observance of the installation instructions may cause fire or
other hazards.

Disconnect the mains voltage before connecting the inputs.

4. Features

• Status indication for each input

• Different phases possible with the 230 V versions

• Separate reference potential for each input with 230 V versions

• Separate reference potentials (GND) for inputs 1 through 3 and 4

through 6 with the 24 V versions

• Supplementary software-independent debouncing circuits for the
inputs integrated

5. Connection

8-channel binary input 230 V (fig. A)
4-channel binary input 230 V (fig B)

The bus is connected via the bus connection terminal (1).
The contacts are connected as shown in fig. A or fig. B.
The reference potential N must be connected separately for each input.
The inputs (E1 through En) can be connected to different phase

conductors.
A signal at the input is indicated by the corresponding LED (2).

6-channel binary input 24 V (fig. C)

The bus is connected via the bus connection terminal (1). The cont acts
are connected as shown in fig. C.

Reference potential GND must be connected separately for inputs 1
through 3 and 4 through 6.

In DC operation, the (E1 through E6) are independent of polarity.
When a signal is present at one of the inputs, the corresponding LED (2)

is lit up.

L Important: For 24 V and 230 V voltages separate cables must be

used.
