Analog Output Wiring
Figure 53 Analog Output Wiring scheme
For analog wiring:
1. Connect field wiring to ZZ-4AO-2 Expansion Module as shown above.
2. The analog outputs on this module are sourcing and provide power to the external device.
Configure Analog Outputs
1. On the Input / Output tab, check to see that all modules and I/O points are listed.
2. Select the ZZ-4AO-2 Module.
3. Set the Analog Outputs for 1 to 10VDC or, 0 to 20mA as needed (setting one sets all for module).
The ZZ-4AO-2 model is a sourcing output and does not require a power supply to complete the loop. Since the current is
sourced there is no need to use an isolator or differential input. This output can connect directly to a standard 0-20mA input.
