Signal Conditioner Modules

Eltek Systems, specialist in developing import substitute products, has introduced SCM/RTD module as a direct replacement for Taylor SCM/RTD module. It operates on 24 V DC supply and generates isolated supply for RTD excitation. Linearisation of RTD input is performed and output current of 4-20 mA is generated which is also isolated from RTD and input supply of 24 V. Auxiliary isolated voltage output of 1-5 V is also available on request. Thus this module has quadruple isolation. Allowable cable resistance is up to 22 Ohms in 3-wire configuration. The accuracy of the module is better than 0.2%. Long term stability is 0.1% per annum making it virtually free from recalibration during its usage. The company also manufactures 4-20 mA/4-20 mA isolator and thermocouple to 4-20 mA isolator with quadruple isolation.
