What this spare part replaces and what it needs
The 6ES7132-0HH01-0XB0 is a spare-part SIMATIC DP electronic submodule for the ET200B distributed I/O station, providing 16 relay outputs split as 4 high-current ports rated at 4 A and 12 ports rated at 2 A with resistive load. It accepts supply voltages from 120/230 V AC or 24 V DC up to 150 V DC, and communicates over PROFIBUS DP at up to 12 Mbit/s. This module is designed for the TB6/AC terminal block — if you're swapping an older unit, verify the existing base matches, because the submodule won't lock onto a different TB variant.
Output current split — why it matters for your load wiring
The 16 outputs are not all equal: two ports handle 4 A each, and the remaining twelve are limited to 2 A. That means you route your heavier loads (contactors, small motors) to the high-current ports and keep the 2 A ports for signal relays or indicator lamps. Relay switching voltage is rated at 230 V AC, and the module draws 210 mA typical from the backplane plus 20 W power loss — budget that heat in the enclosure if the ET200B is densely populated.
Wiring connections use screw-type or spring-loaded terminals for 3- and 4-wire connection, permanently wired. The module has a RUN LED, a bus fault BF (red) LED, and a green status LED per output — useful for on-site fault isolation without a laptop.
