Product Overview

6ES7144-4PF00-0AB0 is a Siemens SIMATIC ET 200pro High Feature analog input electronics module with four channels for thermocouples or ±80 mV signals. It supports thermocouple types B, E, J, K, L, N, R, S and T.

The module provides configurable interference suppression and smoothing, reference-junction compensation options, and channel-level diagnostics for distributed temperature measurements.

Ordering focus: Select the separately ordered CM IO connector module to match the wiring arrangement and verify the ET 200pro station configuration.

Key Functions

Thermocouple and millivolt acquisition

Four channels measure the supported thermocouple types or the ±80 mV voltage range.

Reference-junction setup

Internal, fixed, dynamic and RTD(0) compensation choices support different installed thermocouple wiring methods.

Noise filtering and diagnostics

Selectable 10 Hz, 50 Hz or 60 Hz suppression and smoothing work alongside channel diagnostics and the red SF group-fault indicator.

Frequently Asked Questions

Which thermocouple types can I connect to 6ES7144-4PF00-0AB0?

The module accepts types B, E, J, K, L, N, R, S and T.

Can I use 6ES7144-4PF00-0AB0 for a low-level voltage signal?

Yes, each input can be configured for the ±80 mV measuring range.

How should I compensate the cold junction when wiring 6ES7144-4PF00-0AB0?

Choose internal, fixed, dynamic or RTD(0) reference-junction compensation to suit the installed wiring.

What cable length can I use with 6ES7144-4PF00-0AB0?

Use shielded signal cable no longer than 30 m.

Can I adjust noise rejection on 6ES7144-4PF00-0AB0?

Yes, the module offers 10 Hz, 50 Hz and 60 Hz suppression settings, as well as an off setting.

Which connector module should I order with 6ES7144-4PF00-0AB0?

Order a compatible ET 200pro CM IO connector module separately for the installed wiring arrangement.

How can I identify a channel fault on 6ES7144-4PF00-0AB0?

The module supports channel diagnostics and signals a group fault through its red SF LED.

Compatibility & Ordering Notes

Before ordering 6ES7144-4PF00-0AB0: Match the CM IO connector, thermocouple type and reference-junction method to the existing SIMATIC ET 200pro station configured for four-channel analog input.

Compatibility Checklist for 6ES7144-4PF00-0AB0

• Order the matching CM IO connector module separately; the Siemens product listing identifies CM IO 6ES7194-4..00-0AA0.
• Use shielded signal cables with a maximum length of 30 m.
• For RTD(0) reference-junction compensation, use the specified Pt1000 M12 compensation connector with the CM IO 4×M12 arrangement.
• Type B thermocouples and the ±80 mV range do not use temperature compensation.
