Supply via internal voltage source
ƒ If a freely assignable digital output (e.g. X5/A1) is assigned permanently to HIGH
level, it serves as an internal voltage source. Every output has a maximum load
capacity of 50 mA.
– The relay K
SR
and two digital inputs (X5/28 and e.g. X5/E1) can be supplied with
voltage via a digital output.
– Two digital outputs must be connected in parallel and assigned permanently to
HIGH level in order to obtain the maximum wiring (relays K
SR
and X5/E1 ... X5/E5,
X5/ST1).
ƒ For the supply of the analog inputs (X6/1, X6/2 and X6/3, X6/4) you have to set a
freely assignable analog output (e. g. X6/63) permanently to HIGH level.
