DPM-500 Analog Input Meter Instruction Manual
7
F4 Digital Input
Logic Levels
Logic High: 3 to 5 VDC
Logic Low: 0 to 1.25 VDC
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
page 13 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/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 buttons or digital
inputs
1.
Automatic reset only (non-latching), when
the input passes the reset point.
2.
Aut manual reset at any time (non-
latching)
3.
Manual reset only, at any time (latching)
4.
Manual reset only after alarm condition has
cleared (latching)
Note: Front panel button or digital input may be
assigned to acknowledge relays
programmed for manual reset.
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.
