The ELCM-TC04ANNN temperature measurement module supports 4
channels of thermocouple temperature sensors (J-type, K-type, R-type,
S-type, T-type, E-type, N-type, ±80mV) and converts these signals into
16-bit digital data. You can select temperatures in Celsius (resolution: 0.1°C)
or Fahrenheit (resolution: 0.1°F). The data in the module may be accesses
using the FROM/TO instructions, or you may 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 module.
Further information can be found in the “ELC Programming Manual” and
“ELC Special Modules Operation Manual”.
This module is a 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 connect AC 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

Note 1: Use cables specifically designed for use with thermocouple temperature sensor J-type,
K-type, R-type, S-type, T-type, E-type and N-type, or use double shielded cables to
minimize the effects of noise. Temperature inputs should be separated from power cable
or other wiring that may cause interference.
Note 2: Connect the terminal on both power supply and the ELCM-TC04ANNN to a
proper system 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 the ELCM-TC04ANNN, 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 TC Conversion Curve
You can adjust the conversion curves according to your actual needs by
changing the Offset value (CR#28 ~ CR#31).
Offset in ELCM-TC04ANNN: Deviation digital value from the target value.
