Important Technical Note

The F-2AO is a front-loading plug-in card. It allows you to add analog capabilities without increasing the width of the PLC on the DIN rail.

• Wiring Tip: For current output (4-20mA), ensure you use the I Out and Common terminals. For voltage (0-10V), use the V Out and Common terminals.

Ideal Applications

• Speed Control: Providing frequency references (0-10V) to Variable Frequency Drives (VFDs).
• Flow & Pressure Control: Operating proportional valves and dampers.
• Signal Re-transmission: Sending process variables to external chart recorders or displays.
