DF46 – Analog Outputs Module – Voltage / Current

AVOIDING ELE C TROSTATIC DISCHARGES

Electrostatic discharges may damage semiconductors electronics components found in the boards.
Generally, they may occur when these components or connectors pins in the modules and racks are
touch, without using any appr opriated equi pment to prevent the el ectro static discharges .

It i s extremely recomm endable the following procedures :

• Before handling the modules and racks, discharge the electrostatic charge found in the body
through appropriated equipments or even touching grounded equipments;

• Avoid touching in the electronics components or in the connectors pins in the racks and
modules.

Description

DF46 - ANALOG OUTPUTS MODULE
VOLTAGE / CURRENT

DF46 (1 Group of 4 Voltage/Current Analog Outputs)

This module provides 4 pairs of analog outputs. Each pair is composed of one Current output and
one Voltage output. When one output is selected, the corresponding pair is selected simultaneously.
The current outputs can be configured individually on ranges 0-20 mA or 4-20 mA. For voltage
outputs the range is 0-5V, 1-5 V, ± 5 V, 0-10 V, 2-10 V or ± 10 V.

DipSwitche’s Configuration

When using Voltage Mode, make sure to configure the Group of Ranges via DipSwitches located
UP and Down inside the Box.

DipSwitch 1 - UP Side: Configure the Group of Ranges of Channel 0 (I0/V0)
DipSwitch 2 - UP Side: Configure the Group of Ranges of Channel 1 (I1/V1)
DipSwitch 1 - DOWN Side: Configure the Group of Ranges of Channel 2 (I2/V2)
DipSwitch 2 - DOWN Side: Configure the Group of Ranges of Channel 3 (I3/V3)

See under Technical Specifications (output range) the Group of Ranges.

Notes

In order to attend EMC standards, use shielded cables in signals inputs (ground the shield in the
panel only in one side of the cable) and cables less then 30 meters for power source inputs.

The scale for Analog Input and Output Modules is done using XD_SCALE parameter in AI and
AO blocks, respectively. When using MAI or MAO, it is assumed a default range, 4-20mA or 1­5V without possibility to change. For MAI and MAO, input and output parameters are available in
percentage of default range.
