DIN rail mounted base module RTU520:

Input voltage: 24 VDC, 20 W

Natural convection cooling

Reverse voltage protection

LEDs for monitoring the output voltage

Available with up to 16 RTU520 IO modules

Efficiency: 85 per cent

Features

The Power Supply Unit 520PSD01 has the following features and functions:

– Natural convection cooling

– Electronic power limiting at the outputs

– Short-circuit protection at the output

– Input overvoltage protection

– Reverse voltage protection on inputs

– Potential-free isolation between inputs and outputs

– LEDs to monitor output voltage

When interacting with the 520CMD01. the input voltage (24 VDC) passes through the I/O module.

During power-up, the 520CMD01 switches the 24 V output voltage to the active voltage of the I/O module.

Applications

The Power Supply Unit 520PSD01 generates or switches 24 VDC, ±15 VDC, and 5 VDC for RTU520 systems.

The output power is sufficient to power an RTU520 with up to 16 I/O modules. The input voltage to the power supply unit is 24 VDC.
