Digital Outputs

Digital Outputs
Each drive provides digital (relay) outputs for external annunciation of a
variety of drive conditions. Each relay is a Form C (1 N.O. – 1 N.C. with
shared common) device whose contacts and associated terminals are rated
for a maximum of 250V AC or 220V DC. The table below shows
specifications and limits for each relay / contact.
