1. Introduction
1.1. Foreword
Congratulations on purchasing a high quality DEDITEC product!
Our products are developed by our engineers according to today's required
quality standards. We pay attention already during the development to flexible
expandability and long availability.
We develop modular!
Due to a modular development we shorten the development time and - what of
course benefits the customer - we sell at a fair price!
We ensure a long delivery availability!
If used semiconductors are no longer available, we can react faster. With us
mostly only modules have to be redesigned and not the whole product. This
increases the delivery availability.
1.2. Customer satisfaction
A satisfied customer is our first priority!
If something is not to your satisfaction, just contact us by phone or mail.
We will take care of it!
1.3. Customer response
The best products grow with our customers. We are always grateful for any
suggestions or proposals.

1.4. Brief description
The "MOD-REL8_10A" is a power or expansion module that has eight
changeover relays with a switching capacity of 40V/10A AC or 40V/8A DC.
External low-power outputs e.g. of a PLC, relay or optocoupler can be used for
switching.
24V/DC are required as power supply. An external connection cable to our RO
modules is optionally available. The DIN rail mounting facilitates the
installation at development places and distribution cabinets.

2. Commissioning
2.1. Step 1 - Safety instructions
Before commissioning your DEDITEC product, please familiarize yourself with
this manual and read the following points carefully:
· Damage caused by non-observance of these operating instructions will void
the warranty or guarantee of this product. We do not accept any liability for
consequential damage!
· We do not accept any liability for damage to property or personal injury that
could result from improper handling or non-observance of the safety
instructions!
· Avoid touching electronic components on the circuit board directly. This
could lead to electrostatic discharges and destroy sensitive components. As a
precaution, always discharge before touching an electrically grounded object.
· Unauthorized conversions or technical modifications to this product are not
permitted for safety and approval reasons (CE) and will void the warranty or
guarantee.
· Do not operate the module outside the maximum permissible technical data.
· The product is not suitable for operation in damp or wet environments.

2.2. Step 2 - Connecting the power supply
Select a suitable power supply* with sufficient power of at least 5 watts and an
output voltage of, for example, +7VDC or +24VDC.
The power supply is connected to the 2-pole pluggable screw terminal. Please
note the polarity as shown below. Left V+ and right V-.
* A suitable industrial power supply can be purchased from us as an accessory.
