• When commissioning the instrument, please observe the installation regulations and all

relevant standards (including VDE standards), especially when operating with voltages

higher than 42 V.

• We recommend to always connect unused inputs to the corresponding reference ground to

avoid crosstalk between the input channels.

• Always disconnect your eld wiring from the voltage source before you make or break cable

connections to the card.

Introduction 7

Manual ADQ-51 Rev. 1.0 Introduction

1.3 Installation and assembly site

The ADQ-51 is a digital I/O box designed for industrial use.

The box may only be used in dry rooms. Ensure adequate ventilation and that the connecting

cables are securely seated.

1.4 Brief description

The ADQ-51 digital I/O box is suitable for use in industrial automation and control technology.

The galvanic isolation of 500 VACeff. between the eld wiring and the PC effectively suppresses

interference. To protect against contact bounce, this box also offers the option of programming

a digital lter for each input port.

The ADQ-51 has 8 bit isolated digital inputs. These isolated inputs have a Schmitt trigger cha-

racteristic according to IEC 61131-2 (Type 1) and are designed for a max. input voltage of 35 V.

The digital inputs are equipped with a digital lter.

The ADQ-51 also has 8 bit isolated digital outputs. Each output can drive up to 0.6A. To increase

the output current a parallel connection of several outputs is possible, so that for many appli-

cations no external driver stage is necessary. To supply the outputs, an external voltage source

in the 16..35 V range with sufcient power must be provided. The output drivers are equipped

with thermal overload protection, current limitation, short-circuit protection and undervoltage

monitoring.

2.1 Connecting the box

Please read the manual of your computer regarding the installation of additional hardware

components before installing the box.

The box should be handled with care to ensure that the device is not damaged by electrostatic

discharge (ESD), mechanical stress or unauthorized surges. In addition, precautions must be

taken to avoid electric shock. Follow standard ESD protection measures.

After successful installation you will nd the „ALLDAQ-Manager“ in the info area of the taskbar

(usually at the bottom right) or in the Windows start menu. The ALLDAQ Manager gives you

access to the Software Developer Kit (SDK), various utility programs and help les.

2.2.2 Installation on Linux

Please ask us about the availability!

2.3 Testing program

Simple test programs can be found in the ALLDAQ SDK. There is a subfolder „Applications“ with

test programs for your ALLDAQ hardware for the respective programming language.

You can use the ALLDAQ Manager to query various information about the installed ALLDAQ

hardware.

3.3 Isolated digital inputs

The ADQ-51 has 1 isolated digital input port with 8 bits. The isolated inputs have a Schmitt

trigger characteristic according to IEC 61131-2 (Type 1) and are designed for a maximum input

voltage of 35 V. The ADQ-51 has 1 isolated digital input port with 8 bits. All isolated inputs are

equipped with status LEDs (not visible in the housing). The insulation voltage against PC ground

is 500 VACeff according to EN60664-1 or UL1577.

3.3.1 Digital input lter

You can program a digital lter for each input port to prevent unwanted contact bounce effects.

Choose between the following values:

10 ms (N= 1248) / 3.2 ms (N= 400) / 1.0ms (N = 125) / 10 µs (Bypass). The scan frequency is

100 kHz (typ.).

3.3.2 Wiring

The isolated inputs have a Schmitt trigger characteristic in accordance with IEC 61131-2 (type 1)

and are designed for the UIH input high level of typ. 24 V, which is common in control techno-

logy. Observe the following conditions:

• Threshold voltage L ¨H: > 15 V @ UEXT = 24 V

• Threshold voltage H ¨L: < 11 V @ UEXT = 24 V

• Hysteresis: typ. 1V

The external supply UEXT can be in the range 16..35 V, while we recommend 24 V. Please note

that a ground connection must always be established from the external circuit to the reference

ground of the isolated digital inputs (GND). The digital input part and the digital output part

use a common GND.

3.3.3 Programming

All input ports (DI_x) can be programmed independently of each other. The port direction is

determined by the hardware.

One digital lter can be programmed per port: 10 ms / 3.2 ms / 1 ms / 10 µs (bypass).

3.3.3.1 Read in single value

In this operating mode you can read a digital value in the respective port width.

The procedure is described in the online help.

Function groups Manual ADQ-51 Rev. 1.0

3.4 Isolated digital outputs

The ADQ-51 has an isolated digital output port with 8 bits. The high-path outputs are equipped

with a power FET that switches up to 0.6 A per channel. The isolation voltage against PC ground

is 500 VACeff.

3.4.1 Wiring

The outputs of the ADQ-51 are designed for a high level of 24 V (UOH = 16..35 V) for industrial

applications. The max. output current IO is 0.6 A per channel. To increase the total output cur-

rent, any number of outputs can be connected in parallel. A ground reference to the external

output circuitry must be established via GND. The digital input and output parts use a common

GND.

The output stage offers a comprehensive overload protection, such as::

• Short-circuit-proof outputs (current limitation per channel)

• Switch-off at current peaks of typ. 1.4 A, e.g. with inductive loads

• Overvoltage protection for UEXT > 47 V

• Undervoltage switch-off: UEXT = min. 7 V/max. 10.5 V, restart at max. 11 V,

hysteresis: typ. 0.5 V

• Thermal overload protection with automatic restart. In case of overload (TTSD = typ.

135°C), the respective channel switches off and switches on again automatically as soon as

the junction temperature has dropped by 10°K.

Function groups 15

Manual ADQ-51 Rev. 1.0 Function groups

To supply the output stage, an external voltage source must be connected to the UEXT pins,

which can provide sufcient power. At full load, this is up to 5.6 A for the ADQ-51.

The output ports (DO_x) can be programmed independently. The port direction is determined

by the hardware.

3.4.2.1 Single value output

In this operating mode you can output one digital value each in the respective port width.

Note: An output port can also be read back! Please observe the procedure as described in the

online help.

3.4.2.2 Overloading the outputs

If the output stage is overloaded, the respective port is automatically switched off. Follow the

procedure as described in the online help.
