Jung KNX 2214 REG AM Operating Instructions Manual

KNX 4-channel analog input module
Ref.-no.: 2214 REG AM

Operating Instructions
4-channel analog input module

1. Safety instructions

Attention:
Electrical equipment must be installed and fitted by qualified
electricians only and in strict observance of the relevant
accident prevention regulations.

Failure to observe any of the installation instructions may result in
fire and other hazards.

U

s

and GND must not be interconnected with the corresponding

terminals of another device.
Connected sensors must not be supplied with power from the
connected KNX/EIB device (Risk of irreparable damage!).

2. Function

• This analog input module extends a KNX/EIB weather station
Art. no. 2224 REG W or a KNX/EIB analog input Art. no. 2114 REG
A by four additional sensor inputs for analog transducers.

• Measuring data evaluation and limit processing take place in the
KNX/EIB device.

• The analog input module accepts both voltage and current signals:
Voltage signals: 0 ... 1 V DC 0 ... 10 V DC
Current signals: 0 ... 20 mA DC 4 ... 20 mA DC

• The current inputs 4 ... 20 mA can be monitored for wire breakage
(parameter setting).

3. Installation

The device is snap-fastened on a 35 x 7.5 mm rail as per EN 50022.

An analog input module must be connected to the KNX/EIB device
by means of the 6-pole system connector only (supplied with the
analog input module).

For operation, the 4-channel analog input module needs an external 24 V
power source Art. no. WSSV10.

4. Power supply of connected sensors

• The connected sensors can be supplied from terminals + U

s

and

GND (see fig.

c). These terminals are provided in duplicate and

internally interconnected.

• The total current consumption of all sensors supplied this way must
not exceed 100 mA.

• In the event of overload or short-circuit between +U

S and GND, the

power will be switched off. After removal of the fault, the power is
switched on again automatically.

• Sensors connected can also be supplied externally (e. g. if their
current consumption exceeds 100 mA). In such case, they must be
connected between terminals K1... K4 and GND.

Attention!
U

s

and GND must not be interconnected with the corresponding
terminals of another device.
Connected sensors must not be supplied with power from the
connected KNX/EIB device (Risk of irreparable damage!).
