maxGUARD is a modular system for building customised

24Vcontrol voltage distributors. It consists of electronic

load monitors, potential distribution terminals, and feed-in,

control and alarm modules.

The electronic load monitors selectively protect individual

load circuits against overload and short circuit. They are

available as xed-value variants or with an adjustable trip-

ping characteristic, as well as with a 2-pole output relay.

Active feed-in modules, control modules and alarm modules

are used to control and monitor the electronic load monitors.

Multiple control modules can be used to segment the control

voltage distributor into separate load groups. Alarm modules

can be used to transmit signals potential-free to external con-

trol boards.

All connections between the modules of a maxGUARD sta-

tion are established using cross-connectors. All connection

terminals are PUSH IN connections, are colour-coded and

have an additional 2 mm test socket.

A large number of the modules are available in two perfor-

mance classes:

– standard version with uncoated PCBs

– enhanced version with coated PCBs and enhanced certifi-

cation for maritime applications and applications in explo-

sive risk zones.
