For more information aboutthe optional peripherals, please see ELC Application Manual.• This is an OPEN TYPE Controller. The ELC should be kept in an enclosure away from airbornedust, humidity, electric shock risk and vibration. Also, it is equipped with protective methodssuch as some special tools or keys to open the enclosure, so as to avoid the hazard to usersand 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 willdamage 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 switchedoff or the area is known to be Non-Hazardous.1 INTRODUCTION1.1 Model Explanation and PeripheralsThank you for choosing Eaton Logic Controller (ELC) series products. The analog input modulereceives external 4-point analog signal input (voltage or current) and transforms it into 14 bits digitalsignal. The analog input module of ELC-AN04ANNN can read/write the data of analog input moduleby using commands FROM / TO via ELC program. There are 49 CR (Control Register) in eachmodule and there are 16 bits in each register.1.2 Product Profile and Outline1213 1411MCH3CH1CH2MMEXTENSIONPORT13235 6 87489106090ELC-AN04ANNN3CH4M25.23Units: mm1.
