8. TECHNICAL DATA ON CONTROL CONNECTIONS
94
* If you use 230 VAC as control voltage from the output relays, the control circuitry must be powered with a separate isolation
transformer to limit the short circuit current and the overvoltage spikes. This is to prevent welding on the relay contacts. Refer
to standard EN 60204-1, section 6.2.9.
Digital inputs can be isolated from ground, see chapter 5.2.2.2 Iso-
lation of digital inputs from ground.
Analogue output channel 1, selection 0 ...20 mA, load < 500 Ω
