SCM9B-3000/4000 Series

Computer-to-Analog Output Modules

DESCRIPTION

FEATURES

The SCM9B-3000/4000 series are complete computer-to-analog output

interfaces. They are designed to be mounted remotely from a host computer

and communicate, in ASCII, with standard RS-232 and RS-485 serial ports.

SimpleASCIIcommandsareusedtocontrola12-bitDAC(Digital-to-Analog

Converter) which is scaled to provide commonly used current and voltage

ranges. An 8-bit CMOS microprocessor provides an intelligent interface

betweenthehostandtheDAC. The3000/4000arecompatiblewiththe1000/

2000 input modules and may be mixed in any order.

● ANALOG OUTPUT RANGES: 0-1V, ±1V, 0-5V, ±5V, 0-10V, ±10V,

0-20mA, 4-20mA.

● COMMUNICATES IN ASCII WITH RS-232 OR RS-485 SERIAL PORTS.

● PROGRAMMABLE HIGH/LOW OUTPUT LIMITS.

● 500Vrms OUTPUT ISOLATION.

● 12-BIT OUTPUT RESOLUTION.

● SCALING IN ENGINEERING UNITS.

The modules are easy to use. You do not need engineering experience in

complicated data acquisition hardware. This modular approach to data

acquisition is extremely flexible, easy to use and cost effective. The modules

can be mixed and matched to fit the application. They can be placed remote

from the host and from each other. You can string up to 124 modules on one

set of wires.

● BAUD RATES: 300 TO 38,400.

● NONVOLATILE DIGITAL CALIBRATION.

● OUTPUT PROTECTION: 240VAC (CURRENT OUTPUT).

±30V (VOLTAGE OUTPUTS).

● DIRECT CONNECTION TO ‘DUMB’ TERMINALS OR MODEMS.

● REQUIRES +10 to +30Vdc UNREGULATED SUPPLY.

● MAY BE LOCATED UP TO 10,000 FEET FROM HOST (RS-485).

● ADDRESSABLE: UP TO 124 UNITS PER SERIAL PORT.

● ‘ BUMPLESS’ MANUAL CONTROL INPUTS.

Although software is not required, utility software (SCM9B-S1000) is avail-

able on IBM-compatible diskette to make the 3000/4000 easier to learn and

use. S1000 software is provided at no charge on request with a purchase

order and is not copy protected.

PROGRAMMABLE FEATURES (4000 Series)

(Provides intelligent features not found in the 3000 Series.)

• Fully Programmable Output Slopes: 0.01V/s (mA/s)

to 10,000V/s (mA/s).

• Programmable Data Scaling to any Desired Units.

• True Analog Readback of Output Signal.

• Programmable Starting Value.

• Programmable Watchdog Timer Provides OrderlyShutdown in the Event

of Host Failure.
