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.
