1.0 INTRODUCTION
The 61C613 is an input module for the AutoMater 30/40 and DCS
5000/AutoMaxT. It features 16 individuallyĆisolated analog inputs
capable of multiplexing signals from any combination of
thermocouples and low or high level voltages, or RTDs. The module
must be used in conjunction with either the 61C614 Thermocouple/
Voltage Termination Panel, or the 61C615 RTD Termination Panel.
Two application programming disks are included with the input
module. Both disks contain exactly the same programs. The
programs allow you to verify the functionality of the module.The disks
also include sample programs for reading inputs using the module.
The module provides automatic linearization and cold junction
compensation for type B, E, J, K, R, and T thermocouples.
Thermocouples may be read in either degrees Centigrade or
Farenheit. Thermocouple inputs can be read as often as once every
110 msec. Thermocouple inputs require the use of the 61C614
Thermocouple/Voltage Termination Panel. The module can be used
to convert signals from RTDs, using the 61C615 RTD Termination
Panel. In this mode, the module must be configured for voltage
inputs, typically + 1.25 V.
The module provides offset and span compensation for voltage
inputs. Voltages can range from a full scale of +12.5 mvolts up to a
maximum of +10.0 volts. Voltages may be converted to either 12Ćbit
precision every 45 msec. or 14Ćbit precision every 75 msec. Voltage
inputs require the use of the 61C614 Termination panel.
This manual describes the functions and specifications of the input
module. It also includes a detailed overview of installation and
servicing procedures, as well as examples of programming methods.
