Specifications
Basic Meter
- INPUTS: Field selectable, 4-20 mA, 1-5 V, 0-5 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: NEMA 4X, panel gasket provided.
- CALIBRATION: May be calibrated using internal calibration (I-CAL) or by applying an external calibration signal (E-CAL).
- 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 24VDC at 20 mA regulated. Noise less than 10 mV p-p. 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:.05% of calibrated span.
- 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: Operating temperature range: 0 to 65¡C. Storage temperature range: -40 to 85ûC. Relative Humidity: 0 to 90% non-condensing.
- ENCLOSURE: 1/8 DIN, high impact plastic, UL 94V-0.
- CONNECTIONS: Removable screw terminal block (provided).
- 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: E160849; 508 Industrial Control Equipment.
Relays
- RATING: 2 or 4 relays; 2 Amp SPDT (form 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 load.
- RESET: User Select. 1. Automatically when the input passes the reset point. 2. Automatically + manually (via user supplied switch or front panel ACK button).
- FAILSAFE 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. 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 Transmitter Output
- CALIBRATION RANGE: Anywhere in range of meter, 501 count minimum span.
- OUTPUT LOOP RESISTANCE:
Loop Resistance Power Supply Min Max 24 VDC 10 ohm 600 ohm 36 VDC (external) 600 ohm 1000 ohm
- ISOLATION: 500 VDC or peak AC, input-to-output or input/output-to-power line.
- EXTERNAL LOOP POWER SUPPLY: 35 V max.
