The ELCM-AN04ANNN analog input module supports 4 analog input
channels (either voltage or current) and converts these signals into 16-bit
digital data. You can select voltage inputs or current inputs by the way you
connect your inputs. In addition, you can access the data in the module by
using the FROM/TO instructions, or read the average value of channels
directly by using the MOV instruction (Please refer to allocation of special
registers D9900 ~ D9999).
This instruction sheet provides only information on the electrical
specification, general functions, installation and wiring. It should be read
and understood before attempting to install or use the modules.
Further information can be found in the “ELC Programming Manual” and
“ELC Special Modules Operation Manual”
These analog I/O modules are part of an OPEN TYPE control system.
The ELCM should be kept in an enclosure away from airborne dust,
humidity, electric shock risk and vibration. Your application may require
that the enclosure be locked to prevent non-maintenance staff from
operating the controller (e.g. key or specific tools that are required for
opening the enclosure) in cases where danger and damage to
equipment or personnel may occur. Do NOT touch the terminals while
power is applied.
DO NOT connectAC input power to any of the input terminals; otherwise
serious damage may occur. Check all the wiring before switching on the
power.
Ensure that the ground terminal is properly grounded in order to
prevent electromagnetic interference.
This manual is subject to change without notice.

Note 1: Please isolate analog signals from power wiring.
Note 2: When the analog input module is connected to current signals, make sure you
short-circuit “V+” and “I+” terminals.
Note 3: If ambient electrical noise is significant, please connect FE to the grounding terminal.
Note 4: Please connect the power supply terminal and the analog input module
terminal to a suitable system earth ground.

Explanation on Special Registers D9900~D9999
When ELCM-PH/ELCM-PA controllers use expansion I/O modules,
registers D9900~D9999 will be reserved for storing values from these
modules. You can apply the MOV instruction to access values in
D9900~D9999.
When ELCM-PH/ELCM-PA controllers use ELCM-AN04ANNN analog input
modules, special registers are configured as shown below:

Note 1: D9900 ~ D9999 are average input values of CH1 ~ CH4 and the average times is K1 ~
K100. When the average times is set to K1, the values displayed in D9900~D9999 are
current values. You can use: 1. ELCM_AIO Configuration Function of ELCSoft or 2.
FROM/TO instructions (CR#8 ~ CR#11) to set the average times as K1.
Adjust A/D Conversion Curve
Users can adjust the conversion curves according to the actual needs by
changing the Offset value (CR#28 ~ CR#31) and Gain value (CR#34 ~
CR#37).
Gain: The corresponding voltage/current input value when the digital output
value = 16,000.
Offset: The corresponding voltage/current input value when the digital
output value = 0.
