Instruction Sheet
WARNING
•
This Instruction Sheet only provides descriptions for electrical specifications, general
specifications, installation & wiring, troubleshooting and peripherals. For more information about
the optional peripherals, please see ELC Application Manual.
•
This is an OPEN TYPE Controller. The ELC should be kept in an enclosure away from airborne
dust, humidity, electric shock risk and vibration. Also, it is equipped with protective methods
such as some special tools or keys to open the enclosure, so as to avoid the hazard to users
and the damage to the ELC. Do NOT touch terminals when power on.
•
Never connect the AC main circuit power supply to any of the input/output terminals, as it will
damage the ELC. Check all the wiring prior to power up. To avoid any electromagnetic noise,
make sure the ELC is properly grounded
.
•
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.

INTRODUCTION
1.1 Model Explanation and Peripherals
Thank you for choosing Eaton Logic Controller (ELC) series products. The ELC-AN06AANN allows
the connection of four analog inputs and 2 groups 12 bits digital outputs (voltage/current). The ELC
transforms the input into a 12 bit digital signal and the output into a 2 points analog signal, which may
then be manipulated using TO and FROM commands in the ladder logic program. There are 49
Controlled Registers (CR) in each module (each register is 16 bits). The Analog Input/Output Mixed
Module of ELC-AN06AANN can read/write the data of analog input module by using commands
FROM / TO via ELC program.
