Description
About the TM-PS-B UC
About the TM-PS-B UC
The Siemens 6ES7193-7DB20-0AA0 TM-PS-B UC terminal module holds the redundant power supply for SIMATIC ET 200iSP remote I/O stations, working alongside the TM-PS-A module. It converts an 85-264 V AC supply into 20.4-28.8 V DC at up to 5 A, with isolation tested at 2500 V AC, and carries ATEX and IECEx approvals for Zone 1 gas and Zone 21 dust areas.

Selection Notes
The TM-PS-B UC module mounts alongside a TM-PS-A to carry a second, redundant power supply in the same ET 200iSP station, so pick it when the application needs continued operation if one supply fails. Its 2500 V AC isolation rating and ATEX/IECEx Zone 1 gas and Zone 21 dust approvals make it suited to intrinsically-safe I/O stations inside hazardous process areas rather than general cabinet-mounted installations.
Applications
ET 200iSP stations installed in Zone 1 or Zone 21 hazardous process areas where a redundant 24 V DC supply into the I/O station is required without leaving the hazardous zone for maintenance.
