System data

Environmental conditions
Process and supply voltages
24 V DC Process and supply voltage 24 V DC (-25 %, +30 % inclusive ripple)
Absolute limits 18 ... 31.2 V inclusive ripple
Ripple < 10 %
Protection against reverse polarity yes
Allowed interruptions of power DC supply Interruption < 10 ms, time between 2 interruptions > 1s, PS2
supply
Important: Exceeding the maximum process or supply voltage (< -35 V DC and > + 35 V DC) could lead to unrecoverable damage of the system. For the supply of the
modules, power supply units according to PELV or SELV specifcations must be used. The creepage distances and clearances meet the requirements of the overvoltage
category II, pollution degree 2.

Note: In order to prevent malfunctions, it is recommended that the operating personnel discharge themselves prior to touching communication connectors or perform other
suitable measures to reduce effects of electrostatic discharges. Unused sockets for Communication Modules on Terminal Bases must be covered with TA524 Dummy Communi-
cation Module. I/O-Bus connectors must not be touched during operation.
