The Siemens 6AG1234-4HE32-2XB0 SIPLUS analog I/O slice rated for –40 to 70°C ambient — four differential inputs and two outputs on a 45 mm footprint.
Diagnostics that save a trip
This module flags wire-break and short-circuit per channel, plus a 'For Maintenance' alarm before the loop goes dead. On a remote skid, that means one less drive-out to check a 4-20 mA line. Diagnostic alarms are parameterizable, so you choose what triggers.
Panel fit and power budget
Width is 45 mm — takes one slot on a standard DIN rail. Height 100 mm, depth 75 mm, IP20 so it lives in the cabinet. Draws 60 mA at 24 VDC, typical power loss 2 W. Needs a front connector (order separately).
