Pepper Computer RS232, RS485 user manual B a SE Power Consumption Min

Introduction SMART I/O User’s Manual

The attachment of both units is achieved by sliding them over the DIN rail with the clip assembly pulled out and then releasing it when correctly posi- tioned.

The 24V supply source should possess the following characteristics:

V o l t a g e		Current
min	m a x	Continuous P e a k
18V	36V	400mA	1.5A (2ms)

Because of power limitations, it should be noted that although up to 11 SMART-Modules are possible in a complete configuration, attention should be paid to the following tables that show the individual component power requirements. The maximum of 6750mW should not be exceeded as damage to the on-board DC-DC converter may result due to overheating or entering a reset status due to the thermal cutoff protection switching mechanism.
