Details

Intended purpose The analog input module 07 AI 91 is used as a remote module at the CS31 system bus. It has 8 analog input channels with the following features: • The channels can be configured in pairs for the connection of the following temperature or voltage sensors: • ± 10 V / ± 5 V / ± 500 mV / ± 50 mV • 4…20 mA (with external 250 Ω resistor ) • Pt100 / Pt1000 with linearization • Thermocouples types J, K and S with linearization • Only electrically isolated sensors may be used. • The range of ± 5 V can also be used for measuring 0..20 mA with an additional external 250 Ω resistor.

The configuration of the input channels as well as the setting of the module address are performed with the DIL switches. The 07 AI 91 uses one module address (group number) in the word input range. Each of the 8 channels use 16 bits. The unit is powered with 24 V DC. The CS31 system bus connection is electrically isolated from the rest of the unit. The module offers a number of diagnosis functions (see chapter “Diagnosis and displays”). The diagnosis functions perform a self-calibration for all channels.

Displays and operating elements on the front panel 1 8 green LEDs for channel selection and diagnosis, 8 green LEDs for analog value display of one channel 2 List of diagnosis information relating to the LEDs, when used for diagnosis display 3 Red LED for error messages 4 Test button Electrical connection The module is mounted on a DIN rail (15 mm high) or with 4 screws. The following figure shows the electrical connection of the input module.
