BASIC METER
INPUTS: Field selectable, 4-20 mA, 0-5 V, 1-5 V, 0-10 V.
DISPLAY: Bright, Large, 0.56" (14.2mm) high efficiency red or green LED. 4 1 /2 digits + extra zero; + 19999(0), (0) may be switched on to display 199,990.
FRONT PANEL: Type 4X, NEMA 4X, panel gasket provided.
CALIBRATION: May be calibrated using internal calibration (I-CAL ) or by applying an external calibration signal (E-CAL ). To scale inputs such as 0-5 V, 1-5 V or 0-10 V without applying a signal it is necessary to first complete an Initial Calibration.
CALIBRATION RANGE: 4 mA (1V) input may be set to display anywhere in range of meter. 20 mA (5V) may be set anywhere above or below 4 mA input.
NON-VOLATILE MEMORY: All programming values are stored in non-volatile memory for ten years if power is lost.
LOCKOUT: Jumper 3 at rear of instrument restricts modification of calibration values.
LOOP POWER: (AC powered units only) Isolated 24 VDC ± 5% at 20 mA regulated. Max loop resistance of 1200 ohms. Available for either signal input or 4-20 ma output option, but not both.
HOLD READING: Connect terminals HLD and COM.
ACCURACY: ± 0.05% of calibrated span ± one count.
INPUT IMPEDANCE: Voltage ranges, greater than 300 Kohms; Current range, 100 ohms.
POWER:
AC power: 115 VAC ± 10%, 50/60 Hz, 10VA. 230 VAC ± 10%, 50/60 Hz, 10VA.
DC power: 18-36 VDC, 6 watts max.
ISOLATION: AC power: 1500 VAC; DC power: 500 VDC.
ENVIRONMENTAL: Operational Ambient Temperature Range: 0 to 60°C.
Storage temperature range: -40 to + 85°C.
Relative humidity: 0 to 90% non-condensing.
ENCLOSURE: 1/8 DIN, high impact plastic, UL 94V-O.
CONNECTIONS: Removable screw terminal block
ALARM POINTS: 4, any combination of high or low alarms.
ALARM STATUS INDICATION: Front Panel LED.
ALARM DEADBAND: 0-100%, user selectable.
UL FILE NUMBER: E193723; 508 Industrial Control Equipment
WARRANTY: 1 year parts and labor
EXTENDED WARRANTY : Warranty may be extended an additional 12 months by returning the Product Registration Form within 2 months from date of purchase. Go to www.predig.com for online registration.

RELAYS
RATING: 2 or 4 relays; 2 Amp SPDT (from C). The contacts are rated 2 Amp @ 30 VDC or 2 Amp @ 250 VAC resistive load; 1/14 HP @ 125/250 VAC for NC contacts and 1/10 HP @ 125/250 VAC for NO contacts, inductive loads.

RESET: User Select.
1. Automatically plus manually (via user supplied switch or front panel ACK button).
2. Automatically when the input passes the reset point.

FAIL-SAFE OPERATION: The relay coils are energized in the non-alarm condition. In the case of a power failure, the relays will go to the alarm state, (NC contact is connected to common). May be disabled with internal jumper.

AUTO INITIALIZATION: When power is applied to the meter, the relays will always reflect the state of the input to the meter.

DEADBAND: 0-100%, user selectable.


ISOLATED 4-20 mA OUTPUT SIGNAL
CALIBRATION RANGE: Anywhere in range of meter, 501 count minimum span.

OUTPUT LOOP RESISTANCE:
24 VDC: 10 Ohms min.   600 Ohms max.
35 VDC: (external) 600 Ohms min. 1000ýmax

ISOLATION: 500 VDC or peak AC, input-to-output or input/output-to-power.

ACCURACY: ± 0.1% F.S., ± .004 rnA

EXTERNAL LOOP POWER SUPPLY: 35 V Max.
