Page 11: Lcd Display (Exdul-581E And Exdul-581Poe Only)
3.9 Power over Ethernet (EXDUL-581PoE only) The module supports the IEEE802.3at standard when powered via PoE. The supplied voltage must be between 44V and 57V. IEEE802.3 standard specifies a typical voltage of 48V. EXDUL-581E / EXDUL-581PoE / EXDUL-581S © 2021 by Messcomp Datentechnik GmbH EV06...
Page 12: Getting Started
The EXDUL-581E / EXDUL-581S requires a supply voltage from +10V ... +30V DC at terminal 23 (Vcc) and terminal 24 (GND) to operate. The EXDUL-581PoE can be powered both via the terminals 23 (Vcc) und 24 (GND) as well as via the Ethernet cable using PoE. The power supply via PoE is only used if no power is available at the terminals.
