3.4.8 24V control circuit supply

A 24VDC supply must be provided to power the controlling electronics. This is useful for safety reasons where AC power needs to be removed from the power stage but the controlling electronics must remain powered to retain position and I/O information.

A separate fused 24V supply should be provided for the MicroFlex e100. If other devices are likely to be powered from the same 24V supply, a filter (Baldor catalog number FI0014A00) should be installed to isolate the MicroFlex e100 from the rest of the system. Alternatively, a ferrite sleeve may be attached to the supply cable near connector X2.
