The D204C module is a communication device that performs the function of distributing and amplifying the control-bus signal in those facilities with special characteristics that require it, taking into account the restriction of not installing more than three segments in cascade.

CAPACITY

Each module can distribute the control bus in four branches called BUS1 to Bus4, increasing the bus distance up to 600 m from the control module to the distributor / amplifier and 600 m from the expander / distributor module to the substation.

The system allows to fix the distribution units with a maximum of three links in cascade, allowing to mix copper and fibre bus distributors.

POWER SUPPLY

It operates on 12-Vdc external power, with a consumption of 20 mA when in standby mode and a maximum consumption of 25 mA.

INSTALLATION

The bottom of the equipment is prepared for easy installation on a DIN-standard mounting rail. The connection is made via pluggable terminal block.
