What does this module do in an ET 200AL station?

It provides 8 digital input channels for reading 24 V DC field signals (for example, limit switches and proximity sensors) within an ET 200AL distributed I/O setup.

How many inputs are available and what input standard does it meet?

It has 8 digital inputs and uses an input characteristic in accordance with IEC 61131 (Type 3).

What input voltages are recognised as OFF and ON?

For signal "0" (OFF), the range is -30 to +5 V. For signal "1" (ON), the range is +11 to +30 V (rated input 24 V DC).

What is the typical input current when a channel is ON?

The typical input current for signal "1" is 3.2 mA per input.

What input response time can I expect?

For standard inputs at rated voltage, the input delay is 1.2 to 4.8 ms for both transitions (0→1 and 1→0).

Which sensors can be connected to the inputs?

It is suited to switches and proximity sensors and supports connection of 2-wire sensors. For 2-wire sensors, the permissible quiescent current is up to 1.5 mA.

Does it provide sensor power outputs?

Yes. It includes an integrated 24 V encoder/sensor supply with 8 outputs. The total available output current across all outputs is up to 0.7 A, with electronic short-circuit protection per module.

What connector types does it use?

The I/O connections use M8, 3-pole connectors per channel. Power is supplied via an M8, 4-pole connector. The ET-Connection uses an M8, 4-pin, shielded connection.

What is the maximum recommended cable length to the sensors?

For unshielded sensor cabling, the maximum length is 30 m.

What supply voltage does it require?

The rated load voltage (1L+) is 24 V DC, with a permissible range of 20.4 to 28.8 V DC.

How much current does the module itself consume?

Current consumption is 25 mA at rated voltage, without load.

What environmental protection rating does it have?

It is rated IP65/67, making it suitable for harsh industrial environments where high ingress protection is required.

What operating temperature range is supported?

The permitted ambient temperature during operation is from -25 °C to +55 °C.

What diagnostic features are available?

It supports diagnostic alarming and provides LED indication for channel status (green) and module diagnostics (green/red). A diagnostic for short-circuit to M on the sensor supply can be enabled/disabled at module level.

Is there electrical isolation between channels and the backplane?

Yes. There is isolation between the channels and the backplane bus. Channels are not isolated from each other. Isolation testing is specified at 707 V DC (type test).

What are the physical dimensions and approximate weight?

The module measures 30 mm (W) x 40 mm (D) x 159 mm (H) and weighs approximately 145 g. (Common ordering reference: 6ES7141-5BF00-0BA0.)
