Use the exact Siemens order number and verify the system constraints before procurement.
Place voltage and current transmitters so each two-channel group can share the correct mode.
Choose the narrowest official voltage range or the current range that covers the transmitter output.
Use twisted, shielded analog cable and observe the Siemens 100 m maximum.
Keep signal plus common-mode voltage between −12 V and +12 V.
Selected specialist-brand products requested for regional projects and available on Nordwel.
Auxiliary relay option for protection and control applications.

It is the SIMATIC S7-200 SMART SM AI04 module with four differential analog inputs.
Siemens documents ±10 V, ±5 V, ±2.5 V and 0–20 mA measurement ranges.
Mode is selected in groups of two inputs, so plan channel pairs around the required signal type.
The product designation states 11 bits plus sign for voltage using a 12-bit ADC; current mode is 11 bit.
No. Siemens lists no field-to-logic galvanic isolation for this module.
The maximum withstand values are ±35 V and ±40 mA; they are not normal operating ranges.
Yes. The Siemens system manual lists overflow/underflow and 24 V DC low-voltage diagnostics.
The module consumes 1.5 W and measures 45 × 100 × 81 mm; its listed weight is 147 g.
Software, licensing, controller, interface, shield and power-supply references.
Internal cable references for 40-channel input and output connections to field termination assemblies.
