Temperature measurements represent the numerically

largest group of analog interfaces in industrial automa

tion. All the more reason why technical perfection and

cost-effectiveness are important requirements here. The

AIO112 module types cover both of these requirements in

an exemplary manner. Up to 12 Pt100/Pt1000 sensors can

be cost-effectively connected to a single module using a

2‑wire connection technology.

The temperature is recorded with 16‑bit resolution and,

thanks to special measuring electronics, with very high

sampling rates. Widely adjustable filter chains, precisely

tuned to the signal path, ensure a configurable bal

ance between interference suppression and measurement

dynamics. A hardware-accelerated high-speed interpolation

that can be activated as required provides continuous

measurement signals independent of the filter settings and

even with very short bus cycles. Alternatively, each indi

vidual channel can also be operated as a 14 bit current

output (4 mA to 20 mA, 0 mA to 20 mA).

Plants extended over large distances, interference fields

caused by power engineering systems, difficult grounding

conditions or aggressive substances close to the measure

ment sensors the challenges in analog measurement tech

nology for industrial applications can be manifold.

Floating measurement circuits with differential circuits

must be planned in order to exclude interference from

the measurement chain as much as possible. To prevent

interference and damage from being transmitted from one

sensor circuit to all the others, the measuring and control

circuits are galvanically isolated from each other.

For this purpose, the AIO104/I module type offers the ben

efits of an extremely versatile multi-signal analog input/

output module combined with channel-wise galvanic isola

tion. Each of the 4 primary channels can be operated indi

vidually either as an analog input or output. The spectrum

of the inputs ranges from current loops (4 mA to 20 mA,

±20 mA) to 4 high-impedance voltage measurement ranges

(±10 V to ±10 mV), Pt100/Pt1000 temperature measure

ment in 2-wire, 3-wire, and 4-wire connection technology as

well as thermocouples, and through to freely configurable

resistance measurement. The integrated measuring range

and measured value monitoring enable both sensor circuit

faults as well as process alarms to be implemented easily.

Current loops can also be driven or 0 V to 10 V, ±10 V

voltage signals can be output in 14 bits. Besides the 4 freely

configurable primary channels, up to 4 additional I/O chan

nels with restricted signal types are available.

required signal type

The cost and performance optimized design of complex

automation solutions involves a large number of different

sensor and actuator types. The standard 10 V and 4 mA

to 20 mA interfaces are often not sufficient to achieve

demanding objectives.

With the UIO108. a single module type covers all common

analog and digital signals for inputs and outputs that can

be configured individually for each channel. The extensive

versatility of the module is rounded off by a wide range

of additional functions such as counters, encoders, pulse

width modulation and the control of a stepper motor

driver. This simplifies the entire process from the quotation

phase through planning, programming and commissioning,

right up to stockkeeping and servicing. Besides the 8 freely

configurable primary channels, up to 8 additional I/O chan

nels with restricted signal types are available.

The range of the AIO104/I module type extends from current loops, high-impedance

voltage measuring ranges, temperature measurement via Pt100/Pt1000 sensor in 2-,

3- and 4-wire technology, as well as thermo-couples and free configurable resistance

measurement. The module offers the advantages of an extremely versatile multi-signal

type analog input/output module combined with channel-wise galvanic isolation.

The integrated measuring range and measured value monitoring enable both sensor

circuit faults as well as process alarms to be implemented easily.

The AIM112 module type is particularly useful when a large number of different interfaces

requires a correspondingly large variety of types of acquisition modules. Up to 12 analog

inputs can be individually configured to the desired signal type. Alternatively, channel types

for all industrially relevant thermocouples including integrated characteristic linearization

are available for measuring very wide temperature ranges.

The backplane combines the node adapter and the I/O modules into

a mechanically robust EMC compliant unit. Fully assembled I/O stations

can thus be pre-tested after mounting and transferred to the application

without further modification. Backplanes allow for real-time communication

between modules as well as with the node adapter and provide the power

supply to the logic side of the modules.

The IP40 conform structure and the installation concept of the M100 make

it possible to mount the stations directly on or in the machine, either on a

mounting rail or through direct screw mounting. In addition, the individual

modules are bolted and they remain fixed in place, even if subjected to

vibration or shock loads.

Empty slots on backplanes are useful for optional retrofits, machine

variants or for keeping reserve space in plant construction.

The BPC101 backplane slot cover protects each slot from mechanical

influences, electrostatic discharge and contamination.
