Serial output
ALARMS: (on request)
• Number of outputs: up to four, independent
• Alarm type: up alarm, down alarm, up alarm with latch, down
alarm with latch, phase asymmetry, phase loss, neutral loss.
• Set-point adjustment: 0 to 100% of the electrical scale
• Hysteresis: 0 to 100% of the electrical scale
• On time delay: 0 to 255s
• Relay status: selectable, normally close or normally open.
• Output type: relay, SPDT; AC 1-8A, 250VAC; DC 12-5A,
24VDC; AC 15-2.5A, 250VAC; DC 13-2.5A, 24VDC.
• Min. response time: ≤150ms, filter excluded, set-point on-
time delay: 0
• Insulation: 4000 Vrms output to measuring inputs,
4000 Vrms output to power supply input.
• Note: the outputs can be either relay type or open collector
type (for the latter type of output see the features mentioned
in the PULSE OUTPUT paragraph).
