Module Description and Accessories IP 240

2.2 Technical Specifications

The IP 240 has two independent channels.

In the IP 252 expansion mode, the encoder signals are acquired as in the position decoding and

positioning modes. The data relating to pulse inputs for position decoding therefore also apply to

the IP 252 expansion.

Current consumption, internal Max. 0.5 A at 5 V without encoder supply

Weight Approx. 450 g

Width of the module 1 SPS=20 mm

2.2.1 Position Decoding and Positioning

Pulse inputs

Encoders Incremental encoders

with the following characteristics:

- Encoder signals Two pulse trains displaced by 90 ° (Channels A and B),

one reference signal (Channel Z)

The Z signal is evaluated in zero mark monitoring and

reference point approach during signal state A=”1”

and B=”1”. For the duration of signal Z, states A=”1”

and B=”1” may only occur once ( Section 13.1.1).

- Encoder output circuits with symmetrical pulse train to RS 422 A

or similar,

rated encoder voltage 5 V,

connection to inputs:

A and A, B and B, Z and Z

with asymmetrical pulse train, e.g. push-pull,

open collector (external pull-up resistors required),

rated encoder voltage 5 V or 24 V,

connection to inputs:

A*, B*, Z*

Binary input

Encoders e.g. BERO proximity switches

- Encoder output circuit Switching to P potential

Operating voltage 5 V or 24 V,

connection to input:

IN (preliminary contact)
