Core Technical Specifications

This digital output module delivers robust switching for demanding industrial loads. We engineered the 6ES5436-4UB12 to control high-current actuators with exceptional reliability.

High-Current Output Capability

The 6ES5436-4UB12 provides eight powerful output channels, each sourcing up to 2 A continuously. This capacity allows direct connection to large solenoids, contactors, and heavy-duty indicator lamps. The total load across all channels must not exceed 16 A simultaneously. Consequently, you can eliminate external interposing relays for most applications, simplifying panel design and reducing wiring complexity.

Advanced Thermal Management

This output module maintains exceptionally low on-state resistance below 0.2 Ω, minimizing heat generation during operation. The efficient power dissipation ensures stable performance even at maximum load current. In addition, built-in over-temperature protection safeguards the transistors from overheating under fault conditions. This thermal management extends the module’s service life and enhances overall system reliability.

Robust Protection and Diagnostics

The 6ES5436-4UB12 integrates short-circuit protection on each output channel to prevent catastrophic failures. When a fault occurs, the module limits the current and reports the condition via the system bus. The diagnostic feedback enables your PLC program to identify faulty channels quickly. This real-time visibility allows you to implement conditional logic for safe machine operation and rapid troubleshooting.

Fast Switching Performance

This module handles inductive loads up to 10 W per channel without requiring external suppression circuits. For resistive loads, it achieves a maximum switching frequency of 50 Hz. The integrated freewheeling diode effectively suppresses back-EMF, protecting the output transistors from damage. This robust design suits applications such as conveyor control, valve actuation, and motor starter management.

Superior Electrical Isolation

The 6ES5436-4UB12 provides 1,500 V AC isolation between the field outputs and the backplane logic. This high isolation rating effectively protects the PLC processor from transient surges and ground potential differences. The module draws minimal current from the backplane supply, reducing the burden on the overall system power budget. This efficient operation allows dense rack configurations without overloading the power supply.

Compact and Serviceable Design

This module mounts on standard DIN rails or installs in 19-inch racks with ease. Its compact width of 25 mm maximizes valuable panel space for additional modules. Weighing just 0.48 kg, the 6ES5436-4UB12 places negligible mechanical stress on mounting hardware. You can quickly swap the module during maintenance, minimizing costly production downtime.
