Product Description



IC693ALG391
is a 2-Channel Analog Current Output module for the Series 90-30 Programmable Logic Controller. It offers two output channels with each output having the ability to convert 12 bits of binary (digital) data into an analog output for use as needed by many applications. IC693ALG391 is able to give out outputs ranging from 0 to 20 mA. The converted signal has a resolution of 12 bits binary. However, the sign bit is not needed when converting the output. During each scanning process, the two channels are updated. The %AQ register has 13 essential bits that are changed to sign magnitude by the PLC and forwarded to the module. The D/A converter uses 12 of the bits while the thirteenth bit (sign) is utilized to check whether negative data has been forwarded to the module.

If IC693ALG391 receives negative data, it outputs the low end of the current range of 4 mA to 20 mA range. The software tends to reject any value more than 32767 keyed in the modules. The IC693ALG391 gives two output ranges that are 4 and 20 mA. These two output ranges have user information laid down to make sure that a count of 0 is equal to 4 mA and a count of 32000 is equal to 20 mA. Every 1000 additions equal to 0.5 mA. In case the CPU is switched to  STOP mode or RESET, when measuring Current Output, 4 to 20 mA Output, 0 to 20 mA the condition of the module changes to either Default to 0/4MA or Hold-Last-State. Choosing the suitable condition is created by arranging the DEF0/4 jumper on the detachable terminal board connector on the module.

Every 2-Channel Analog Current Output can be utilized as a current source/less accurate voltage source. A voltage is an output at VOUTx which is equal to the current output. The voltage range relies on the layout of the current output range and may be added with the use of a 250-ohm resistor instead of voltage jumper. An isolated +24 VDC power supplied by the PLC power supply is the primary power source provider for IC693ALG391. There are two terminals offered to the module's I/O terminal board for user-supplied +24 volts. These terminals are important since they offer a standby power supply to enable the outputs to retain their value when the internal supply is lost and Hold-Last-State is chosen.

When the applied voltage is higher than the isolated +24 VDC that is from 21.5 volts to 26.5 volts, the the user supply is utilized. Further, an inside voltage source of about +24V is produced within the module to run the current loop outputs. These current loop drivers are source type drivers. To reduce the loading and noise capacitive, all field linked to the module should be wired with the help of a good grade of twisted and protected tool cable connected to GND. This GND link offers access to the baseplate leading to turning down of noise. Three of Analog Current Output modules can be set up when the user given suppliers are not used to power the module.

Procedure for IC693ALG391 Field Calibration

●   What you will need:

❍   Calibrated DIM capable of displaying 20 mA +/- 1uA.

❍   Calibrated DVM capable of displaying 5 VDC +/- 1 mV.

❍   IBM PC / Compatible running LM90 or a HHP.

❍   Resistor - 2K ohm @ 1% tolerance.

❍   Non-Conductive Potentiometer adjuster.

1.    Power off the 9030 PLC that has the analog card that is in need of calibration.

2.    Remove any field wiring.

3.    Wire the Current input and Common leads on the DIM to terminals 3 and 5 on the Analog Card respectively.

4.    Power on the DIM and the 9030 PLC. Allow the Analog module a minimum warm-up period of 5 minutes.

5.    Hook up the HHP or PC to the 9030 PLC. Go to the assigned reference address of this module in the data tables and set the


output of channel 1 to 0000H.

6.    Verify the accuracy of channel 1 for the following results:

Calibration Verification

                                                       STATE            OUTPUT              ACTUAL                     ERROR

                                                       0                     0000H                  4.000 mA                    +/- 8 uA

                                                       HS                  3E80H                  12.000 mA                  +/- 8 uA

                                                       FS                   7D00H                 20.000 mA                  +/- 8 uA


FS = Full Scale, HS = Half Scale 7.  If channel 1 is out of specifications, go to the modules reference address and set the output for 0000H, then adjust P2 (offset ch1) for a reading of 4 mA +/- 2 uA on the DIM. After the offset adjustment, the gain is calibrated by setting the output for 7D00H (FS), then adjusting P1 (gain ch1) for a reading of 20 mA +/- 2 uA on the DIM.

 

8.        If P1 was adjusted then repeat step 6.

9.        Power off the 9030 PLC. Remove the DIM connections from the terminals. Connect the DIM Current input and Common leads to terminals 4 and 6 on the analog card respectively.

10.    Repeat steps 4 through 8 for channel 2 and substitute P3 for P1 and P4 for P2.

11.    Power off the 9030 PLC and install the 0 to 20 mA range jumpers for channels 1 and 2. Jumper terminals 14 and 16 (for channel 1), then 18 and 20 (for channel 2) of the user terminal connector.

12.    Wire the Current input and Common leads on the DIM to terminals 3 and 5 on the Analog Card respectively.

13.    Power on the 9030 PLC. Allow the Analog module a minimum warm-up period of 5 minutes.

14.    Verify the accuracy of channel 1 for the following results:

Calibration Verification

                                                              STATE            OUTPUT              ACTUAL                     ERROR

                                                              0                     0000H                  0.000 mA                    + 10 uA

                                                              FS                   7D00H                  20.000 mA                  +/- 10 uA

FS = Full Scale

15.    Power off the 9030 PLC. Remove the DIM connections from the terminals. Connect the DIM Current input and Common leads to terminals 4 and 6 on the analog card respectively.

16.    Repeat steps 13 and 14 for channel 2.

17.    Power off the 9030 PLC. Remove the DIM and 0-20 mA range jumper connections from the terminals. The voltage output option is used by installing a jumper between terminals 3 and 9 (for channel 1), then 4 and 10 (for channel 2). Connect the 2k resistive load across terminals 1 and 5 (for channel 1), then 2 and 6 (for channel 2).

18.    Connect the DVM Voltage input and Common leads to terminals 1 and 5. Power on the 9030 PLC.

19.    Verify the accuracy of channel 1 for the following results:

 

20.    Power off the 9030 PLC and remove the DVM connections from terminals 1 and 5. Connect the DVM Voltage input and Common leads to terminals 2 and 6. Power on the 9030 PLC.

21.    Verify the accuracy of channel 2 using the chart in step 19.

22.    Re-seal P1,P2,P3 and P4 with an anti-static potentiometer sealer.
