Analog Input Modules

The ADAM-4000 series of 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, the data is sent

in the desired format over the RS-485 network.

The ADAM 4000 series analog input modules protect

your equipment from ground loops by providing 3000

isolation.

The ADAM-4011/4011D/4012 modules feature digital

inputs and outputs which may be used for alarms and

event counting.

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 signals

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 allows the on/off control of a device to perform

independently of its host PC.

Event Counter

The onboard 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 record

repetitive operations.

Analog Input/Output

Modules

The ADAM-4016 is an analog input/output module with

3000 V

isolation for load cell and stress measurement.

It accepts voltage and current input signals. The module

includes two digital outputs for programmable alarm

output and another two digital outputs for individual use.

This enables the ADAM-4016 to control a device's on/off

control independently of a host PC.

Eight-channel Analog

Input Modules

The ADAM-4017+/4018+/4019+ 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

optical isolation

between the analog input and the modules protects the

modules and peripherals from damages caused by high

input-line voltages.

Analog Input Module

with LED Display

The 4½ -digit LED display on the face of the ADAM-4011D

lets you monitor process readings right at their source. The

module displays readings in a wide variety of data formats

as well as high-low alarm messages. The ADAM-4011D

offers flexibility, ease of installation and direct availability

of process data. This module is 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.
