PD8-6200 Explosion-Proof Analog Input Flow Rate/Totalizer
Instruction Manual
19
Relays
Rating
4 SPDT (Form C) internal and 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
for details.
Relay
Assignment
Relays may be assigned to rate, total,
grand total, or Modbus input
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 (2-4 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
digital input, external contact closure on
digital inputs, automatically via user
selectable preset value and time delay, 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.
