ELC-EX08NNSN
Switch-Type Digital Extension Module Instruction Sheet
1 WARNING
•Please read this instruction carefully before use.
•ELC-EX08NNSN is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust, humidity,
electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key or specific
tools are required to open the enclosure) in case danger and damage on the device may occur.
•DO NOT tough any terminal when the power is switched on
•Warning – Do not disconnect while circuit is live unless area is known to be non-hazardous.
•Power, input and output (I/O) wiring must be in accordance with Class 1, Div. 2 wiring methods - Article 501-10(B)(1) of the
National Electrical Code.
•Suitable for use in Class 1, Division 2, Groups A, B, C, D or Non-Hazardous locations only.
•Warning – Explosion hazard - Substitution of components may impair suitability for Class 1, Division 2.
•Warning – Explosion hazard - Do not disconnect equipment unless power has been switched off or the area is known to be
Non-Hazardous.
2 INTRODUCTION
1. Thank you for choosing ELC series programmable logic controller. ELC-EX08NNSN shall be used together with ELC SLIM TYPE
occupying 8 input points. Including MPU, the digital I/O can be extended to maximum 256 points. Besides, maximum 8 special
extension modules (AN02NANN/AN04ANNN/AN04NANN/AN06AANN/PT04ANNN/TC04ANNN/MC01) are extendable from MPU.
2. No external power supply and signals are required, ELC-EX08NNSN allows you to directly control its input points by its switches.
3. As digital switches, ELC-EX08NNSN is able to input instructions without required external wiring for receiving signals. Besides,
ELC-EX08NNSN is handy and safe for using in teachings.

4 INSTALLATION
1. Use a screwdriver to
open the side cover
and reveal the
connecting port.
2. Use the screwdriver
to lift and unfasten
the fixing clip.
3. Accurately connect
the extension module
to the MPU by using
the pinholes at each
corner.
4. Secure the
extension module to
the MPU by pushing
down the fixing
clips.
5. Order of the I/O point No.: The input points of the first extension module are lined up from X20 and output points are lined up from
Y20. The rule applies to all MPU connections with extension modules of any number of points.

5 TROUBLESHOOTING
Input LED Indicator
The On/Off of input signals can be indicated by the input LED indicator. When the input is On, the LED will be on. If error occurs, please
check if the loops of the LED and input signal are normal by using HHP/ELCSoft. Please also be aware that:
1. Do NOT place ELC-EX08NNSN under direct sunlight and please avoid placing it next to overheating objects in case the
high temperature will affect the functions of ELC-EX08NNSN.
2. Please clean the airborne or conductive dust on the panel on a regular basis.
