SC-2345 refers to both the SC-2345 connector block and the SC-2345 with configurable connectors. SCC refers to any SCC Series signal conditioning module. What You Need to Get Started To set up and use the SCC-CO20, you need the following items: ❑ Hardware –... -
Page 4: Device Specific Information
Plug the SCC-CO20 into either SC-2345/2350 analog output socket J(X+17), where X is 0 or 1. The SC-2345/2350 routes the voltage output of E/M Series DAQ device analog output channel AO (X) to the SCC-CO20. Connecting the SCC-CO20 to a Load Note The signal names have changed. - Page 5 Figure 1. SCC-CO20 Signal Connections to E/M Series DAQ Device Using the Isolated Loop Supply of the SCC-CO20 You can connect the SCC-CO20 to a load using either the isolated internal loop supply or an external supply. The internal loop supply outputs a voltage of 15 V with respect to the isolated ground reference.
- Page 6 If your load is grounded and you are using the internal supply, connect the load ground to the current sink terminal at pin 2 on the SCC-CO20. Do not connect the load ground to the isolated ground terminal because doing so could defeat the module isolation.

- Page 9 Calibrating Gain and Offset Errors The SCC-CO20 is calibrated at the factory before shipment. If you want to adjust the gain and offset of the SCC-CO20 in your system using an E/M Series DAQ device, you need a current meter (ammeter) with an accuracy of at least ±2 μA.
- Page 10 Normally you would adjust to 0 μA in order to calibrate the offset, but because Note the SCC-CO20 cannot source current, it is impossible to know when you have adjusted past 0 μA. Using the SCC-CO20 The SCC-CO20 is a 0 to 20 mA programmable current sink. The current output is controlled by AO (X), a 0 to 10 V unipolar DAC output channel of an E/M Series DAQ device.
