      Overview Manuals Common Applications Product Precautions
      ABB TB521-ETH, order number 1SAP112100R0170, is an AC500 CPU terminal base that accepts one processor module and two plug-in communication modules and provides an Ethernet RJ45 connection.
      • Product type: AC500 CPU terminal base
      • Model: TB521-ETH
      • Order number: 1SAP112100R0170
      • CPU slots: 1

      It forms the electrical and mechanical base of an AC500 station by connecting the installed CPU and communication modules, distributing the documented 24 V DC supply, and linking the first S500 I/O terminal unit through the I/O-Bus. The base routes I/O and diagnostic data over the I/O-Bus and exposes COM1, COM2, FBP, and Ethernet connections; the installed compatible CPU and communication modules execute the PLC application and protocols. TB521-ETH itself does not independently measure analog or digital field signals or run the control program. It is used with ABB PM5xx-ETH CPUs, compatible communication modules, FieldBusPlug devices, and S500 expansion I/O in industrial machine and process-control panels where serial, Ethernet, fieldbus-slave, and local-I/O connections are required in one documented AC500 station.

      Important Notice: Verify TB521-ETH and the complete R0170 order code; do not substitute the later R0270 article or the ARCNET R0160 base without ABB-approved project engineering.

      Important Notice: The first link is the product-parameters PDF prepared only from the cited manufacturer information; the second link is the Apter Power product manual. Confirm the physical nameplate, current manufacturer documents, and host-system requirements before installation or replacement.

      Networked AC500 controller station
      Hosts one PM5xx-ETH CPU and exposes its Ethernet RJ45 connection for programming and documented industrial communications.
      Multi-protocol machine control
      Provides COM1, COM2, Ethernet, and FieldBusPlug connection points for a configured AC500 controller in production machinery and process skids.
      Local S500 I/O expansion
      Links the CPU to S500 expansion modules over the I/O-Bus for field-signal acquisition and actuation performed by the installed I/O modules.
      Industrial PLC control panels
      Supports documented AC500 panels for conveyors, pumps, packaging, material handling, water systems, and process auxiliaries when the exact CPU and module compatibility is confirmed.
      Read and follow the current ABB documentation and host-equipment instructions before work. Verify the complete physical nameplate and system configuration.
      1
      Verify the full order code 1SAP112100R0170; R0270 is a different article and must not be treated as an automatic drop-in replacement without ABB documentation.
      2
      Use an Ethernet-type PM5xx-ETH CPU; ABB states that the terminal-base network type must match the CPU type.
      3
      Isolate 24 V DC power and follow ABB's AC500 mounting, disassembly, ESD, grounding, and wiring procedures before inserting or removing the CPU, couplers, terminals, or I/O units.
      4
      Never exceed 30 V DC at the process or supply terminals; ABB warns this can destroy the system.
      5
      Observe polarity at the duplicated L+ and M terminals. ABB warns that incorrect duplicated-terminal wiring can short-circuit and damage the supply, fuse, or terminal base.

Lifecycle Status: unknown for exact R0170. ABB's cited 2007 manual documents the article; the current ABB web product page is for distinct order code R0270. No cited ABB source assigns R0170 an Active, Classic, Limited, or Obsolete phase or formally identifies R0270 as its replacement.

      FAQS

      • What is ABB TB521-ETH 1SAP112100R0170?
        It is an AC500 CPU terminal base for one CPU and two communication modules with an Ethernet RJ45 connection.
      • Does TB521-ETH execute the PLC program?
        No. The installed AC500 CPU executes the application; the base provides slots, terminals, and interface connections.
      • How many communication modules fit?
        ABB documents two communication-module slots for TB521.
      • Which network connection is provided?
        The ETH variant provides an Ethernet RJ45 interface that must match a PM5xx-ETH CPU.
      • Which other interfaces are available?
        ABB lists I/O-Bus, COM1, COM2, and a fieldbus-neutral FBP slave interface.
      • What serial protocols can COM1 support?
        With the compatible CPU, COM1 supports online access, free protocol, Modbus RTU master/slave, and CS31 master.
      • Can COM2 be used for CS31?
        No. ABB states that COM2 is not intended to establish a CS31 system bus.
      • How many S500 I/O expansion modules can be connected?
        The standard documented limit is seven. Up to ten requires PS501 version 1.2 or later and CPU firmware 1.2.0 or later.
      • What are the dimensions and weight?
        ABB lists 123.5 x 135 x 75 mm with CPU inserted and a weight of 215 g.
      • Is 1SAP112100R0270 the same order code?
        No. R0270 is a distinct ABB article. No cited ABB source establishes automatic interchangeability with R0170.
      • What is the lifecycle phase of R0170?
        The exact phase remains unknown because the cited ABB sources do not label R0170 Active, Classic, Limited, or Obsolete.
      • What are the country of origin and tariff code?
        They remain unknown for exact R0170 because the cited ABB sources do not publish those fields.
