Signal modules

￿Analog input/output modules and binary input/output modules are available as signal modules.

Analog input and output modules The following modules are available:

•Analog input module with 8 channels and power supply for transmitters, floating,

6DS1 701-8AB

For input of 8 analog, floating process signals (transmitter sig- nals) for further processing in the central unit of the automation system. The module powers 8 transmitters in a two-wire or four- wire system.

HART-compatible transmitters can be connected to the mod- ule without influencing the measured signal. External analog

distribution is possible in the case of current measurements. The max. value for the load is 150 Ω.

•Analog input module with 8 channels and power supply for transmitters, non-floating,

6DS1 730-8AA

For non-floating input of 8 analog process signals (transmitter signals) to the central unit of an automation system. The mod- ule powers 8 transmitters with a two-wire or four-wire system. The input signal can be divided in the case of a current circuit via two Z diodes per channel.

The input signals can be measured at test sockets on the front panel.

•Basic module with 4 channels for thermocouples, resis- tance thermometers and process signals, floating, 6DS1 731-8RR, and

measurement-point extension module with 14 channels, 6DS1 703-8RR

For direct acquisition of 4 temperatures (floating) with thermo- couples or Pt 100 resistance thermometers. Process signals of 0 to 20 mA or 4 to 20 mA can also be connected to all 4 chan- nels, 0 to 10 V can also be connected to channel 1.

The analog input module can be extended by 2 x 14 inputs using measurement-point extension modules.

Linearization of the input signals and compensation of the cold junction temperature are carried out on the module. The char- acteristics for standard thermocouples and Pt 100 resistance thermometers are stored in the module. Adaptation to special thermocouples is possible by means of corresponding config- uring.

The module has 4 free analog outputs for voltage and another 4 for current.

The analog module must be configured. The PC is connected via the front plug of the module. 1)

•Analog output module with 4 channels, floating, 6DS1 702-8RR

To output 4 analog signals of 0 to 20 mA or 4 to 20 mA. These are available at the process interface for further processing by analog instruments or systems.

The output signals can also be output as voltages of 0 to 10 V

or 2 to 10 V for loads with a very high internal impedance (Ri > 500 kΩ).
