What the I2t rating means for your fuse selection
The 6ES7132-0GF00-0XB0 carries an I2t rating of 0.05 A²·s, measured with starting current inrush. That figure is what you hand to the panel builder for sizing the branch-circuit fuse or breaker protecting this module — it tells you the energy the output circuit can withstand before the semiconductor junction lets go. A fuse with a lower I2t let-through than the module's rating will clear before the module fails. This is a spare-part designation for the SIMATIC DP electronic module used in the ET 200B distributed I/O system. It provides 8 relay outputs rated for 24 V DC to 60 V DC, with resistive load capacity of 2 A at 24 V DC, 1.5 A at 48 V DC, and 1 A at 60 V DC.
PROFIBUS DP integration and physical fit
The module communicates over PROFIBUS DP at up to 12 Mbit/s, with a bus fault LED (red) and a RUN LED for status at a glance. It supports SYNC capability for coordinated output updates across multiple stations on the bus.
Output ratings and channel isolation
Each of the 8 relay outputs is individually isolated — there is no grouping of channels. The module provides potential separation between the electronic block and the PROFIBUS DP bus, and between the digital outputs themselves. This matters when you are driving loads on different voltage potentials from the same module. Maximum inductive load switching is 0.5 A at 30 V DC. The module does not include short-circuit protection on the outputs, so each output circuit needs its own overcurrent protection device sized per the I2t rating.
Environmental limits and operating conditions
Rated for horizontal installation from 0 °C to 60 °C (derated to 40 °C for other mounting orientations). Humidity tolerance spans 15 % to 95 % RH, Class 2 per IEC 1131-2. The module is tested to IEC 60068-2-27 for shock (15 g, 11 ms half-sine) and IEC 60068-2-6 for vibration (10-150 Hz, 1 g constant acceleration). Typical power loss is 2 W. Current consumption from the L3+ logic supply is 130 mA. The permissible DC supply range is 18.5 V to 30.2 V.
