Bachmann AIO104/I Analog Input/Output Module

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.
