Product Overview
The SIPLUS SM331 is a conformally coated eight-channel analog input module for 0/4 to 20 mA HART signals, based on the Siemens SM331 hardware and specified for an extended -25 to +70 °C temperature range.
Eight channels acquire 0/4 to 20 mA process signals and support HART communication with suitable field devices. Eight supply outputs support compatible two-wire transmitters, with short-circuit protection on the transmitter feeds. Conformal coating and the extended -25 to +70 °C rating support installations beyond the standard module temperature range.

Frequently Asked Questions
Which field signals can I wire to 6AG1331-7TF01-7AB0?
Use compatible 0 to 20 mA or 4 to 20 mA analog transmitters with HART communication where required.
Can 6AG1331-7TF01-7AB0 power two-wire transmitters?
Yes; each of the eight channels has a protected transmitter-supply output for supported two-wire devices.
How long can the shielded signal cable be for 6AG1331-7TF01-7AB0?
The shielded cable length can be up to 800 metres when the installation follows the prescribed wiring rules.
Are the input channels of 6AG1331-7TF01-7AB0 isolated from one another?
No; the channels are not mutually isolated, although the channel group is isolated from the backplane bus.
What supply should be provided to 6AG1331-7TF01-7AB0?
Provide a 24 V DC load supply with the specified polarity and protective arrangement.
Why is 6AG1331-7TF01-7AB0 used instead of the standard SM331 version?
The SIPLUS version adds conformal coating and an extended -25 to +70 °C operating-temperature rating.
What should be recorded before replacing 6AG1331-7TF01-7AB0?
Save the channel ranges, transmitter type, HART parameters, diagnostic settings, wiring assignments and hardware configuration.
Compatibility & Ordering Notes
Compatibility Checklist
- Use the module only in a compatible S7-300 or approved ET 200M hardware configuration.
- Confirm two-wire or four-wire transmitter wiring and the associated isolation conditions for every channel.
- Preserve channel scaling, HART configuration and diagnostics before exchanging the module.
