ABB TA571-SIM:AC500-eCo, Input simulator for onboard IO, 6 switches, 24VDC
ABB TA571-SIM 1TNE968903R0203 is a 24 V DC AC500-eCo digital input simulator with six switches for manually simulating onboard PLC inputs DI0 to DI5 during commissioning, programming and troubleshooting.
Why Choose the ABB TA571-SIM 1TNE968903R0203 Input Simulator?
The ABB TA571-SIM 1TNE968903R0203 is a dedicated digital input simulator for ABB AC500-eCo PLC CPUs, designed to simplify commissioning, testing, training and troubleshooting of PLC applications. The compact accessory provides six integrated switches for manually simulating the onboard digital inputs DI0 to DI5 of compatible AC500-eCo CPU modules.
Designed specifically for 24 V DC applications, the TA571-SIM allows engineers to change individual digital input states without connecting external sensors or switches. Each of the six switches represents a digital input, with open and closed positions enabling straightforward verification of PLC programs, input assignments and machine-control logic during development and commissioning.
The simulator connects directly to the terminal block of the CPU's onboard I/O and also incorporates the terminal connection required for the CPU power supply. It is intended for compatible ABB AC500-eCo PM55x and PM56x CPU modules, providing a convenient hardware tool for automation engineers, system integrators, maintenance technicians and training environments.

Convenient PLC Input Simulation and Commissioning
Testing PLC software normally requires digital input signals from sensors, switches or other field devices. The ABB TA571-SIM provides these test signals directly at the compatible AC500-eCo CPU, allowing each of the six onboard digital inputs to be manually switched between open and closed states. Engineers can therefore verify program logic and input responses before the complete machine or field installation is available.
The simulator is particularly useful during control panel commissioning, PLC programming and fault diagnosis. By providing predictable manual input states, it helps engineers isolate software and wiring issues, verify sequences and test control functions without repeatedly modifying external field wiring.
Typical Applications
- AC500-eCo PLC commissioning.
- PLC program and logic testing.
- Digital input function verification.
- Control panel testing and factory acceptance testing.
- Industrial automation troubleshooting.
- PLC training and educational systems.
- Machine development and prototype testing.
