3500 Series General Specifications

Physical / Environmental

Case

DIN package outline of extruded metal, with splash-resistant front panel

Mounting

Clamp slides allow mounting in user's precut panel (for cutout dimensions, see diagram below—maximum panel thickness allowed is 0.24" (6 mm))

I/O Connections

Secure rear connections via screw terminals (except for the Model 3578 AC Strain Gage Conditioner, which uses a special Conditioner Connector requiring direct solder-terminal attachment of cable leads—see diagrams, below

Instrument Dimensions (Bench-Mount)

ESD Immunity

Meets Class 3 Industrial Standard (8 kV) everywhere on the case and on every line

Operating Temperature Range

0° C to +50° C (+32° F to +122° F)

Storage Temperature Range

-40° C to +80° C (-40° F to +176° F)

Operating Humidity Range

10 to 95% maximum, noncondensing

Instrument Weight

Approximately 3.25 lb (1.47 kg)

Power & Display

Voltage

90-265 VAC (eliminates the need to convert between 110-V and 220-V levels)

Frequency

50-400 Hz

Consumption

10 W maximum

Display

5-digit LCD reflective, non-light-emitting

Signal Conditioning (ALL MODELS)

A/D Conversion

16-bit; approximately 1-kHz conversion rate; transparent autocalibration every 2 seconds

Analog Filtering

See individual model specifications

Digital Filtering

Quieting factor selectable from front panel or by computer-port command

Internal 15-Segment Linearization

Programmable from front-panel or by computer-port command

Positive Peak Capture

See individual model specifications

Logic Functions

Limit Logic

Three limit zones (LOW/OK/HIGH) with front-panel annunciation and corresponding TTL-level logic outputs (see Logic I/O); outputs for LOW and HIGH limit conditions can be latching or nonlatching; each limit setpoint has a user-settable hysteresis window to prevent toggling of the limit output from signal noise

Logic I/O

TTL- and CMOS-compatible; isolated (±1500 V) from power and communication ports.  Negative-true outputs for limit monitoring (isolated +5 V provides up to 50 mA for driving external devices directly); negative-true inputs for control of PRINT, TARE, PEAK, and UNLATCH functions (see diagram, below).

Logic Inputs*

Voltage at Current

0

0.45 V (max.) @ 10 mA (sink)

1

2.6 V (min.) @ 0.5 mA (source)

* The minimum time allowed between activation and reactivation of any logic input is 100 ms.

Analog Output

Full-Scale Range

±5 V nominal; ±8 V maximum
Range is scalable in 0.1% increments between 74.5% and 125.5% of nominal input.  Except for the Model 3540, may be sourced by conditioned input

  • (A) after the FIXED ANALOG FILTER (see individual models);
  • (B) after PEAK CAPTURE; or
  • (C) after the SELECTABLE ANALOG FILTER (see individual models)

Allowable Loading

5 mA, maximum

Offset Range Adjustment

±25.5% in 0.1% increments

Offset Accuracy

0.1% maximum

Span Accuracy

0.2% maximum

Offset and Span Drift

±50 ppm/°C; ±20 ppm/month

Frequency Characteristics and Step-Response Settling Times

These characteristics vary with the model number and selected analog output source point (A, B, or C); see individual model specifications

Configuration

Single-ended, return to System Common

Communications

Serial

9-pin RS232/RS485 port (interface mode selectable by instrument "node number" setting); standard baud rates from 300 through 153.6K for both RS232 and RS485; RS485 configuration allows operation as an individual data-collection "node" within a computer-controlled network*

Parallel

IEEE-488 interface available as option, using the Daytronic Model 10CIF488A Interface Adaptor

* NOTE: RS485 conversion is required at the computer's I/O port (see the Models 5D485 and 5E25); the RS232 output may be converted to RS422 standards by means of an optional Model 10E422.
