Relays
Rating
2 or 4 SPDT (Form C) internal and/or
4 SPST (Form A) external; rated 3 A
@ 30 VDC and 125/250 VAC resistive load;
1/14 HP (
≈
50 W) @ 125/250 VAC for
inductive loads
Noise
Suppression
Noise suppression is recommended for
each relay contact switching inductive
loads; see
Deadband

High or Low
Alarm
User may program any alarm for high or
low trip point.
Unused alarm LEDs and relays may be
disabled (turn off).
Relay
Operation
•
Automatic (non-latching) and/or
manual reset
•
Latching (requires manual
acknowledge) with or without clear
•
Pump alternation control (2 to 8 relays)
•
Sampling (based on time)
•
Off (disable unused relays and enable
Interlock feature)
•
Manual on/off control mode
Relay Reset
User selectable via front panel button, F4
terminal at back of meter, external contact
closure on digital inputs, or through serial
communications.
Time Delay
0 to 999.9 seconds, on & off relay time
delays. Programmable and independent for
each relay
Fail-Safe
Operation
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.
Auto
Initialization
When power is applied to the meter, relays
will reflect the state of the input to the meter.
Additional
Relays
An external module, model
, is
available to add 4 SPST 3 A relays to the
meter.
