DIGITAL OUTPUTS
Three alarm relays
1A-30 VAC or 0.5A-50 VDC on a resistance load
Configurable to Normally Open [NO] or Normally Closed [NC] contacts by changing the
jumper positions.
Potential Electrocution Hazard. Connect only safety low voltage < 33 VAC RMS.
One "instrument system alarm" relay per instrument
1A-30 VAC or 0.5A-50 VDC on a resistance load
Normally closed [NC] (NO relay also available) when instrument is turned on. Opens when
a system alarm is detected, and when it does not receive any signal.
Potential Electrocution Hazard. Connect only safety low voltage < 33 VAC RMS.
