ADAM 4000 Series

3-4

Single Module,

Multiple Input Types

and Ranges

The ADAM-4011/4011D Analog Input

Modules can be remotely configured for

14 different combinations of input types

and ranges (T/C, mA, V, mV). You save

on spare parts since you only have to

stock one model.

Analog Input Modules

Analog input modules use

microprocessor-controlled

high-resolution 16-bit sigma-delta

A/D converters to acquire sensor signals

such as voltage, current, thermocouple

or RTD. They translate analog data into

one of the following formats:

engineering units, % of FSR, two’s

complement or ohms. After the modules

receive a request from the host, they

send the data in the desired format over

the RS-485 network.

ADAM analog input modules protect

your equipment from ground loops by

providing 3000 V

DC

isolation.

All analog input modules, except for the

ADAM-4013, feature digital inputs and

outputs which may also be used for

alarm and event counting.

Digital Input/Output

The analog input module’s two digital

output channels are open-collector

transistor switches that you can control

from the host computer. By switching

solid state relays, the output channels

can control heaters, pumps and other

power equipment. The module can use

its digital input channel to sense the

state of a remote digital signal.

Programmable Alarm Output

Analog input modules include high and

low alarm signalling with remotely

configurable limit values. After every

A/D conversion, the digital value is

compared with the high and low limit.

The module can change the state of a

digital output depending on the result of

this comparison. This lets it perform

On/Off control of a device independent

of the host PC.

Event Counter

The on-board event counter can count

up to 65,535 transitions occurring on

the digital input. The counter can be

read and cleared by the host computer.

The counter can be used in production

line applications to keep a record of

repetitive operations.

Eight-channel

Analog Input Modules

The ADAM-4017/4018 are 16-bit,

8-channel analog input modules that

provide programmable input ranges on

all channels. These modules are an

extremely cost-effective solution for

industrial measurement and monitoring

applications. 3000 V

DC

optical isolation

between the analog input and the

modules protects the modules and

peripherals from damage due to high

input-line voltages.

ADAM

Analog Input Modules

with LED Display

The 4½ -digit LED display on the back of

the ADAM-4011D/4014D lets you

monitor process readings right at their

source. The modules display readings in

a wide variety of data formats as well as

high-low alarm messages. The

ADAM-4011D/4014D offers flexibility,

ease of installation and direct availability

of process data. These modules are the

ideal choice for critical process

monitoring.

Eight-channel Analog

Input Data Logger

The ADAM-4018M features six

differential and two single-ended

channels. Its 128 KB of Flash memory

can accommodate up to about 38,000

data samples and will write until the

memory is exhausted. Featuring a

remotely configurable sampling interval

of 2 seconds to 18 hours, the

ADAM-4018M is the perfect link between

industrial processes and your PC,

enabling remote process monitoring

from virtually any kind of computer.
