Physical Dimensions and Component Layout

This unit measures 23.0 cm in length and 13.0 cm in width. Its total height reaches 5.0 cm including terminal blocks. 6ES5130-3WE63 weighs 0.58 kg for DIN rail mounting. You will find 156 discrete components on a four-layer PCB.

Moreover, the unit integrates a 2200 µF bulk capacitor bank. This bank stores energy for 40 ms during power dips. It also filters high-frequency noise from the 24V DC supply.

Integrated I/O and Expansion

The onboard I/O includes 16 digital inputs and 16 transistor outputs. Each input accepts 24V DC from switches or sensors. Each output sources 0.5 A for small loads like indicator lamps. You can expand I/O using the external S5-100U modules if needed.

Processing Performance and Memory

The 8-bit processor executes 1K instructions in just 1.2 ms. This speed handles simple sequencing and logic control tasks easily. The 8KB RAM stores ladder logic programs for small machines. A lithium battery retains memory for up to 200 days without external power.

Connector Interfaces and Programming

A 25-pin D-sub connector provides the TTY programming port. This port uses a 20 mA current loop for reliable communication. Two separate 20-pin terminal blocks handle the integrated I/O wiring. LED indicators show power status, run/stop, and I/O activity.

Typical Application Scenarios

You can deploy 6ES5130-3WE63 in small conveyor systems and packaging machines. It also works well for pump control, fan sequencing, and gate automation. This unit controls small batch processes and material handling stations. Its 8KB memory suits applications with up to 64 I/O points.
