HINWEIS!
Galvanic isolation of relay outputs DO2 and DO3
Mixed switching of mains voltage AC 230 V and SELV or PELV voltage is not admissible due to the basic
insulation between the relays!
(1) Terminal strip I out Current output AO1 (4 to 20 mA)
L+
V+ (positive power supply)
L- 0 V (ground for the power supply)
PE Functional ground, wired at the plant (  see "Terminal strip 1: Connecting
the grounding cable ", page 27)
