Additional specifications and description
24 VDC power supply
This 24 VDC switch mode power supply offers protection against short-circuit, overload and overvoltage. The overload function prevents damage to the power supply due to an overcurrent of the load. In case of short circuit, it simply shuts down until the fault condition is removed. The overvoltage protection prevents that excessive voltage is applied to the load - even in case of instable input voltages. Only the output channel offers 24 VDC supply. The input channel is only used for the Modbus RTU repeater.
Modbus RTU repeater
This is not just a power supply. It's also a galvanic isolated, half-duplex line repeater for Modbus RTU communication. It can be used to interconnect Sentera devices and to reinforce Modbus RTU communication. It helps to establish a stable communication in applications with long cable lengths and high distance between the different Sentera devices.
E.g. DPOM8-24-20 can reinforce the Modbus communication in applications where the distance between different Sentera devices becomes so long that communication gets disturbed. PDM-8-MB guarantees a stable Modbus communication, even in case of longer cable lengths.
The wide range of supply voltage (85 - 264 VAC, 50-60 Hz) makes them compatible with most applications.
Easy to connect
The load can be connected via the terminal blocks or via the RJ45 connectors.
DIN rail mounting
This device can be mounted on a standard DIN rail, preferrably in an electric cabinet. The enclosure offers an IP20 protection against dust and dirt.
