(depending on
internal resettable fuse impedance)
Input
Overload Current input protected by an internal
resettable fuse, 30 VDC max. Fuse resets
automatically after fault is removed.
HART
Transparency The meter does not interfere with existing
HART communications; it displays the
4-20 mA primary variable and it allows the
HART communications to pass through
without interruption. The meter is not
affected if a HART communicator is
connected to the loop. The meter does not
display secondary HART variables.
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
Switching Inductive Loads on
page 18 for details.
Deadband 0-100% of span, user programmable
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 (2-8 relays)
•
Sampling (based on set point and time)
•
Off (disable unused relays and enable
Interlock feature)
•
Manual on/off control mode
Relay Reset
(Acknowledge)
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 PDA1004 , is
available to add 4 SPST 3 A relays to the
meter.
