What the ratings mean for a sourcing decision
The 6AG1134-4GB01-2AB0: Rated for -25 °C to 60 °C ambient, this module handles unheated cabinets or warm panels without derating. The 2-input count sets the BOM line for analog sensing; each input is individually parameterizable for wire-break detection (enabled by default). Selectable integration time of 16,7 ms or 20 ms provides line-cycle rejection. Digital filtering offers 1x, 4x, 32x, or 64x cycle times; basic conversion per channel is 65 ms. Group diagnostics and overflow/underflow alarms are enable/disable per channel group, and the module reports a group error (SF LED red) on any fault. Isochronous mode is not supported, so this is not the right part for time-synchronous applications. Reverse-polarity protection on each input limits destruction to 35 mA per channel. CE and UL approvals are present — sufficient for most industrial control panels but verify if your facility requires additional marks.
