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 - 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.
