@ 30 VDC and 125/250 VAC resistive load;
1/14 HP (≈ 50 W) @ 125/250 VAC for
inductive loads
Noise suppression is recommended for
each relay contact switching inductive
loads; see Switching Inductive Loads on
page 19 for details.
0-100% of span, user programmable
User may program any alarm for high or
low trip point.
Unused alarm LEDs and relays may be
disabled (turn off).
•
Automatic (non-latching) and/or
manual reset
•
Latching (requires manual
acknowledge) with or without clear
•
Pump alternation control (2 to 4 relays)
•
Sampling (based on time)
•
Off (disable unused relays and enable
Interlock feature)
•
Manual on/off control mode
User selectable via front panel button, F4
digital input, external contact closure on
digital inputs, or through serial
communications.
0 to 999.9 seconds, on & off relay time
delays. Programmable and independent for
each relay
Programmable and independent for each
relay.
Note: Relay coil is energized in non-alarm
condition. In case of power failure, relay will
go to alarm state.
When power is applied to the meter, relays
will reflect the state of the input to the meter.

USB port provides power to the meter.
DO NOT apply AC or DC power to the
meter while the USB port is in use.
