EL1252, EL1252-0050, EL1254 - LEDs and pin assignment

LEDs

LED	Color	Meaning
INPUT 1 INPUT 2 INPUT 3* INPUT 4*	green	off	There is no input signal at the respective input
INPUT 1 INPUT 2 INPUT 3* INPUT 4*	green	on	Input signal at the respective input

*) EL1254 only

Note

EL1252-0050: damage to the terminal possible!

In the project planning of the Bus Terminal system, observe the different potentials on the power contacts (24 V_DC and 5 V_DC) and if necessary use separation terminals (EL9080) to isolate the potentials!
