CAN Expansion Module CEMA

Expansion for use of an additional

control unit, Version 10

RE 95 340/11.04 1/6

Features

– A control unit can be used to electronically actuate a hydraulic

drive. The CEMA CAN expansion module allows an additional

RC2-2 control unit to be used, which provides a master

control unit with supplementary inputs and outputs.

– The inputs and outputs are designed for use with Rexroth

hydraulic pumps and motors.

– Diagnostics and conﬁ guration are carried out using the

BODEM PC software or the BB-3 control panel.

– Monitoring for wire breaks and short circuits
