LDGRB-01 3BSE013177R1 ABB analog input/output module

product description：

The analog input/output module 07 AC 91 is used as a remote module on the CS31 system bus. It contains 16 analog input/output channels that can be configured in two operating modes:
• Operating mode “12 bits”: 8 input channels, individually configurable ±10 V or 0…20 mA, 12 bit resolution plus 8 output channels, individually configurable ±10 V or 0…20 mA, 12 bit resolution
• Operating mode “8 bits”: 16 channels, configurable in pairs as inputs or outputs, 0…10 V oder 0…20 mA, 8 bit resolution
• The configuration is set with DIL switches.
• The PLC offers an interconnection element ANAI4_20 for measuring signals of 4…20 mA (refer to 907 PC 331, connection element library).
The module 07 AC 91 uses up to eight input words on the CS31 system bus plus up to eight output words. In the operating mode “8 bits”, 2 analog values are packed into one word.
The operating voltage of the unit is 24 V DC. The CS31 system bus connection is electrically isolated from the rest of the module.
The module offers a number of diagnosis functions (see chapter “Diagnosis and displays”).

1 8 green LEDs for channel selection and diagnosis
2 8 green LEDs for analog value display of a channel
3 List of diagnosis information relating to the LEDs, when they are used for diagnosis display
4 Red LED for error messages
5 Test button
