DSCL24 (Multi-Channel

)

Factory Configurable Isolator - DIN or Panel Mount

Description

Each multi-channel DSCL24 module provides up to 252 different configurations

of process current or voltage inputs and outputs. The factory default setting

provides 4-20mA input and output current. Alternatively, users may complete

and submit a specific configuration table that instructs the factory on how to solder

in configuration jumpers.

Each module provides full 3-way isolation with 2300Vrms CMV input to output

and 3700Vrms CMV power supply to I/O protection. Two module versions are

offered that accept universal power supply of either 24 to 60VDC or AC and

85 to 230VDC or AC with the alternating current usage accepting 45 to 400Hz

power.

NOTES:

(1) 250+ unique I/O ranges are factory configurable. See Table 1 for configuration options.

Configuration Options

The default setting of factory stock modules is 4 to 20mA for both module input

and output.

Alternatively, users may complete and submit Table 1 specifics that the factory

will use to apply solder-in jumpers configuring the module as desired.

NOTE: Modules once configured for a specific user I/O range cannot be

subsequently reconfigured.

Factory Configuration

Check-mark the desired Input and Output range for each channel in the table

at right. Copy and submit this configuration sheet with your purchase order. The

factory will assign a DSCL24-xxxx part number to your specific configuration.

This part number may be used on subsequent orders. The Span and Zero

potentiometers allow ±10% adjustments beyond the following factory solder

jumper settings.
