Aux Contacts - Output

The Output terminal provides eight (OUT1 thru OUT8) form "A" NO (Normally Open) dry type
programmable contacts to drive annunciation signals sourced or "wetted" by external
monitoring devices. All output contacts are rated for NEC Class 2 operation (30VDC /
1ADC.)
The output dry contacts should be operated at their rated values or lower. Figure 4-18
illustrates a typical installation. The external relay can be a lamp, LED, computer, etc.
