The input module‘s address is set by the coding switch built into the PHC control
module. The setting of the coding switch is presented in the PHC software under the
menu item „
Components
g
Edit Modules
“.
Make sure that no identical module addresses are given for PHC input modules.
The setting of the coding switch may be carried out by technicians only. For this the
PHC module needs to be switched off and it must be ensured that there can be no
electrical discharge.

warranTy conDITIons
These operating instructions are an integral part of both the device and our terms of
warranty. They must be handed over to the user. The technical design of the appliance
is subject to change without prior notification.
PEHA
products are manufactured
and quality-checked with the latest technology according to applicable national and
international regulations. Nevertheless, if a product should exhibit a defect,
PEHA
warrants to make remedy as follows (regardless of any claims against the dealer to
which the end user may be entitled as a result of the sales transaction):
In the event of a justified and properly established claim,
PEHA
shall exercise its
prerogative to either repair or replace the defective device. Further claims or liability
for consequential damage are explicitly excluded. A justifiable deficiency is deemed to
exist if the device exhibits a structural, manufacturing, or material defect that makes it
unusable or substantially impairs its utility at the time it is turned over to the end user.
The warranty does not apply to natural wear, improper usage, incorrect connection,
device tampering or the effects of external influences. The warranty period is 24 months
from the date of purchase by the end user from a dealer and ends not later than 36
months after the device’s date of manufacture. German law shall be applicable for the
settlement of warranty claims.
DIsPosaL oF The DevIce
Do not dispose of old devices in the household waste! The device must be
disposed of in compliance with the laws and standards of the country in which it
is operated! The device contains electrical components that must be disposed of
as electronics waste. The enclosure is made from recyclable plastic.
DescrIPTIon
The PHC 940/24 EM input module has 16 inputs
(
I
0-
I
15)
, which are switched to
earth (0V) by switches or buttons. The 24 V direct current of the inputs are provided
by the module.
All inputs can be used with switches or buttons without feedback signals (LED).
connecTIon DIaGram
On 0 V port (earth) is intended for each 2
button inputs. The 0 V ports are internally
connected in the module. It needs to be
ensured that the button is operated with
the earth of the module to which they are
connected.
Please note!
The buttons are connected with the 24
V power supply of the PHC system.
It therefore needs to be ensured that
no connection is established to 230
V alternating current circuits. Such a
connection can make the entire PHC
system defective.
mounTInG
The installation of the PHC modules may be carried out by authorised technicians only.
During installation the system‘s electricity has to be switched off. The PHC module is
designed for mounting on a 35mm top hat rail acc. EN 50022 in in-/on-wall distribution
housing. The devices can be mounted directly next to each other.
attention!!
The PHC modules may
not
be employed in connection with devices that
may endanger people, animals or property when operated.
The following points must be observed:
- the valid laws, standards and regulations
- the technical state of the art during installation
- the PHC manual and the operating instructions of the PHC modules.
- Operating instructions can only cite general stipulations. These are to be viewed in
the context of a specific system.
The following systems may not be switched by Phc output modules:
- safety switches such as EMERGENCY OFF
- emergency power supplies
- fire alarm systems
- emergency lighting systems
DaTa connecTIon
The connection between PHC control unit and other PHC modules is established by
the PHC bus line and the modular connectors of the modules. The module connectors
are switched parallel in the modules (except in the PHC power supply unit) and
therefore freely selectable as in- or output. Thus the PHC module can be positioned
anywhere in the data line.
A PHC bus line of 30 cm length is included with every PHC module. It is needed for
connecting a neighbouring module or for connecting a module in the next distributor
row. The modules are supplied with voltage by the bus line. Power needs to be
switched off before disconnecting the bus line.
