1 MTN1 Eaton Logic Controller ELCM TC Temperature s INSTRUCTION SHEET [Applicable Temperature modules] ELCM-TC4ANNN IL546E

2 4A I-TC The ELCM-TC4ANNN measurement module supports 4 channels of thermocouple sensors (J-type, K-type, R-type, S-type, T-type, E-type, N-type, ±8mV) and converts these signals into 16-bit digital data. You can select s in Celsius (resolution:.1 C) or Fahrenheit (resolution:.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 D99 ~ 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 s 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 power to any of the 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.

Explanation on Special Registers D99~D9999 When ELCM-PH/ELCM-PA controllers use expansion I/O modules, registers D99~D9999 will be reserved for storing values from these modules. You can apply the MOV instruction to access values in D99~D

8 When ELCM-PH/ELCM-PA controllers use the ELCM-TC4ANNN, special registers are configured as shown below: # #1 #2 #3 #4 #5 #6 #7 D132 D1321 D1322 D1323 D1324 D1325 D1326 D1327 D99 D991 D992 D993 D994 D995 D996 D997 D991 D9911 D9921 D9931 D9941 D9951 D9961 D9971 D992 D9912 D9922 D9932 D9942 D9952 D9962 D9972 D993 D9913 D9923 D9933 D9943 D9953 D9963 D9973 Description Code CH1 average CH2 average CH3 average CH4 average Note 1: D99 ~ D9999 are average values of CH1 ~ CH4 and the average times is K1 ~ K1. When the average times is set to K1, the values displayed in D99~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-TC4ANNN: Deviation digital value from the target value.
