Product Introduction
The Siemens 6ES7138-4CB10-0AB0 Industrial Automation Module is a Simatic DP Power Module PM-E designed for the ET200S distributed I/O system. This module provides reliable load voltage monitoring and distribution to electronic modules in its voltage group. With reverse polarity protection, replaceable fuse, and diagnostic LEDs, it ensures system uptime and simplifies troubleshooting.
Technical Specifications Breakdown
The key parameters of the Siemens 6ES7138-4CB10-0AB0 enable versatile operation across both DC and AC applications:
-
Rated load voltage: 24 VDC to 56.7 VDC, or 24 VAC to 48 VAC / 120 VAC / 230 VAC – handles a wide range of industrial power supplies.
-
Reverse polarity protection: Yes – prevents damage from incorrect DC wiring.
-
Power dissipation (max.): 5 W – low thermal load improves cabinet energy efficiency.
-
Insulation test voltage: 1500 VAC – ensures galvanic isolation between load and backplane bus.
-
Diagnostic function: Yes – with red SF and green PWR LEDs for immediate status feedback.
-
Current-carrying capacity: Up to 10 A (DC) or 8 A (AC) at 30 °C, derated at higher temperatures.
Industry Applications
In manufacturing lines, the Siemens 6ES7138-4CB10-0AB0 powers control valves and actuators with reliable AC/DC voltage. For material handling, it monitors load voltage for up to 10 electronic modules in a group, reducing downtime from voltage faults. Its replaceable fuse (5x20 mm) allows quick restoration without module replacement.
Maintenance & Reliability
The Siemens 6ES7138-4CB10-0AB0 is built for long service life. Replace the fuse only when blown, using IEC 127-2/1 250V 10A fast-acting type. Keep the fanless module in a clean, dry environment up to 60 °C. No periodic calibration is needed; visual inspection of LED status ensures proactive fault response.
Compatibility & Integration
This power module integrates seamlessly into Siemens ET200S systems. It must be placed to the right of the interface module (e.g., IM151-1). Use with TM-P terminal modules to feed supply voltage. Supports DC and AC loads without parameter assignment, making it a universal solution for mixed voltage groups.
Selection Guide & Purchasing Advice
Before ordering, verify your terminal module type and load voltage range. The Siemens 6ES7138-4CB10-0AB0 is a standard component for ET200S. For authentic parts and fast shipping, rely on PLC Source PRO (ubest101). Ensure your system power and ambient temperature match the derating curves provided.
