Product details

SIPLUS variant of the standard S7-1200 analog I/O slice, this 6AG1234-4HE30-2XB0 gives you four differential inputs (0-20 mA or ±10/5/2.5 V) and two outputs, all rated for -40°C to 70°C ambient. That temperature floor is the main reason to reach for the SIPLUS line — standard S7-1200 analog modules stop at 0°C. The 24 VDC rail draws 2 W typical; differential inputs reject common-mode up to 12 V, which helps in long cable runs near drives.

Mechanical dimensions: 45 mm wide, 100 mm high, 75 mm deep. IP20 housing with diagnostics for wire-break and short-circuit alarms. Front connector required (ordered separately).

Sibling: 6AG1234-4HE32-4XB0

The -4HE32-4XB0 has a different I/O configuration; verify channel count before substituting. Both are SIPLUS with the same mechanical profile and front connector.

Frequently asked questions

What approvals does it carry?

CE mark and FM approval are confirmed in the specification. No RoHS or UL statement in the listing, but CE covers EU directives including RoHS.

Will 6AG1234-4HE30-2XB0 replace 6AG1234-4HE32-4XB0 without rewiring?

The mechanical footprint and front connector are the same, but the I/O count differs: this module has 4 inputs and 2 outputs, while 6AG1234-4HE32-4XB0 carries a different I/O configuration. Review your channel count before swapping.
