3RK1400-1DQ02-0AA3

What type of industrial module is this?

It is a Siemens K60 compact digital I/O module designed to connect field sensors and actuators to an AS-Interface network.

How many digital inputs and outputs does the module provide?

The module provides four digital inputs and four digital outputs, arranged as two groups of two inputs and two outputs.

Which fieldbus system does the module use?

It operates as a standard slave on an AS-Interface, commonly abbreviated to AS-i, industrial communication network.

What type of electrical connections are provided?

The inputs and outputs use four standard M12 screw-type sockets with Y-assigned connections, allowing two signals to be carried through each applicable socket.

What is the module's environmental protection rating?

The enclosure is rated IP67, making it suitable for installation directly in industrial field environments when correctly fitted and connected.

What voltage is required from the AS-Interface network?

The specified AS-Interface operating voltage range is 26.5 to 31.6 V.

Does the module require an auxiliary power supply?

Yes. An external AUX POWER supply of 20 to 30 V DC is required for the output circuits. This supply must comply with PELV requirements and protection class III.

What type of input signals can be connected?

The four DC digital inputs are designed for PNP signals and can be connected using two-wire or three-wire technology. The minimum high switching level is 10 V.

What is the output switching configuration?

The module has four PNP transistor outputs. Each output is rated at 1 A at 24 V DC, with a maximum combined output current of 4 A.

How much sensor current is available?

The sensor supply is provided through AS-i and has a combined current capacity of up to 200 mA for all inputs at an ambient temperature of 40°C.

What is the maximum AS-i current consumption?

The maximum total current drawn from the AS-Interface network is 270 mA.

What status indicators are fitted?

Yellow LEDs indicate input and output states, a green LED indicates auxiliary power, and green and red LEDs display AS-Interface and diagnostic conditions.

What operating temperatures can the module withstand?

The specified operating temperature range is -25°C to +85°C. The storage temperature range is -40°C to +85°C.

What are the module's dimensions?

The Siemens 3RK1400-1DQ02-0AA3 measures approximately 60 mm wide, 152 mm high and 29 mm deep.

Is a mounting plate included with the module?

No. The K60 mounting plate must be ordered separately. The specified compatible mounting plate is 3RK1901-0CA00.

How can the module be mounted?

It can be installed on a standard rail or mounted to a wall using the appropriate K60 compact-module mounting plate.

Where is AS-i addressing performed?

Addressing is carried out through the dedicated addressing socket located on the front of the module.

What output monitoring features are built in?

The outputs include integrated short-circuit and inductive-load protection, together with a watchdog function.
