small but super power for your automation 731 relay box is the name of the new switchable power supply automated systems require the switching of heating systems pumps valves thermostats or other external devices for this relays are needed that can switch the line voltage or low voltage on and off when required the switching step should be effected by a titrino titroprocessor sample changer or any other metrohm instrument via «remote» lines the new 731 relay box combines all these requirements in a housing of only 10 cm x 19 cm x 23 cm alternating voltage the 731 relay box offers four voltage outputs two 115/230 v alternating voltage outputs are used for switching the line voltage as the maximum power output is 1150 w per output the instrument is also suitable for the power supply of loads with a high power consumption such as heating baths or thermostats or direct voltage the 731 relay box also has two direct voltage outputs whose voltage can be set to values of 5 10 18 or 24 v one cable is enough a very wide range of metrohm instruments can control the relaiy box via their «remote» interfaces no matter what type of instrument you are using one single standard cable 6.2125.100 suffices for communication the 731 relaiy box scans the 14 input lines and switches the assigned voltage outputs correspondingly everything configured at the turn of a switch the user has the possibility to connect each voltage output to its own signal line or to link one signal line with several outputs simply turning the selector switch is all that is needed to configure the instrument fig 1 back and front of the practical 731 relay box.
