Liquiline CM44P

Endress+Hauser

Basic rule for hardware

upgrades

Please note the following if upgrading the device:

• The sum of all current inputs and outputs may not exceed 8!

• A maximum of two "DIO" modules may be used.

Determining the hardware

delivery status

You must be aware of the type of modules and the number of them supplied with the device you

have ordered to determine the delivery status of your Liquiline.

• Basic module

One basic module in all versions. Always occupies slots 0 and 1.

• Fieldbus module

Optional, and only one fieldbus module is possible.

• Input modules

• Must be clearly assigned to the number of optional inputs ordered.

• Examples:

2 current inputs = module 2AI

2 inputs for photometer sensors = module PEM

4 Memosens inputs = 2 inputs with basic module + module 2DS with 2 further inputs

• Current outputs and relays

Various module combinations can exist.

The following table will help you determine which modules your device has, depending on the type

and number of outputs.

Current outputs

Relays

1 x 2R

1 x 4R

1 x 2AO

1 x AOR

1 x 2AO + 1 x 4R

1 x 4AO

1 x 4AO + 1 x 2R

1 x 4AO + 1 x 4R

1 x 4AO + 1 x 2AO

1 x 4AO + 1 x 2AO + 1 x 2R

1 x 4AO + 1x 2AO + 1 x 4R

‣ Sum up the number of modules and sort them according to the specified sequence →  7.

 This will give you the slot assignment for your device.

Terminal diagram

The unique terminal name is derived from:

Slot no. : Port no. : Terminal

Example, NO contact of a relay

Device with 2 inputs for digital sensors, 4 current outputs and 4 relays

• Base module BASE2-E (contains 2 sensor inputs, 2 current outputs)

• PEM module (1 photometer sensor)

• 2AO module (2 current outputs)

• 4R module (4 relays)
