ABB 07DC92 GJR5252200R0101

ABB 07DC92 GJR5252200R0101 is a 16-channel digital control (relay output) module designed specifically for ABB's AC 800M high-end process control systems. This module provides relay contact outputs, enabling direct driving of AC or DC loads such as contactors, intermediate relays, indicator lights, and solenoid valves. It's changeovercontact

The digital input/output module 07 DC 92 is used as a remote module on the CS31 system bus. It contains 32 inputs/outputs, 24 V DC, in 4 groups with the following features:

• The inputs/outputs can be accessed individually

  • as input, • as output or • as re-readable output (combined input/output)

• The outputs

  • work with transistors, • have a nominal load rating of 0.5 A and • are protected against overload and short circuit.

• The 4 groups of inputs/outputs are electrically isolated from each other and from the rest of the unit.

• The module occupies two digital addresses for inputs and outputs on the CS31 system bus. It is possible to configure the unit solely as an output module. In this case, the addresses for the inputs are not needed.

The unit works with a supply voltage of 24 V DC.

The system bus connection is electrically isolated from the rest of the unit.

The module offers several diagnostic functions.

Displays and operating elements on the front panel：

①32 yellow LEDs to indicate the signal status of the configurable inputs and outputs

②List of diagnosis information concerning the LEDs when they are used for diagnosis display

③Red LED for error message

④Test button

Normal operation：

• The module automatically initialises after the power has been switched on. During that time, all LEDs are switched on.

• When the CS31 system bus does not run, LED ③  flashes.

• LED ③ goes out again when the bus operation runs correctly, and the module does not recognise an error.

• The 32 yellow LEDs ① show the signal status of the 32 channels.

Addressing：

An address must be set for each module to enable the central unit to correctly access the inputs and outputs. A detailed description of "Addressing" can be found in the chapter "Addressing" for the central processing unit and coupler. The address setting is accomplished with the DIL switch located under the slide cover on the right side of the module housing.

Acknowledging outputs after a short-circuit：

When an overload or short-circuit occurs, the output limits the current and thermally switches it off. The LED of the overloaded output is flashing.

After the overload or short-circuit is corrected, the outputs are switched on again automatically. A manual acknowledgement or one initiated by the user program is not necessary. The error message has to be acknowledged.

I/O configuration：

Module 07 DC 92 does not store configuration data. The 32 configurable channels are defined by the user program as inputs or outputs, which means that through reading and writing data in the user program, each configurable input/output channel can be used as input, output, or rereadable output.
