| Additional options for CT16A (board level) 934: Analog retransmission of Process Variable or Set Variable: (4 to 20 mADC) For use as recorder, transmitter or computer A/D input. Linearized 4 to 20 mA DC signal follows the Process or Set variable. Scalable. 936: Analog retransmission of Process Variable or Set Variable: (0 to 10 VDC) Similar to option 934, but output signal is linearized 0 to 10 VDC. 948:4-Stage setpoint: Four preset setpoints may be selected by external contacts. Each set point has its own set of PID values giving controller 4 distinct "recipes" for different process situations. 992: RS-485 Computer communication link: Allows remote computer to read and write all control parameters. 993: RS-232 Computer communication link: Allows remote computer to read and write all control parameters. |
