1 Overview
1.1 Range of applications
The Metrohm 731 Relay Box is a versatile auxiliary instrument which
can be used in may different ways for switching various peripheral
devices in complex automated systems. It has been designed
specially for factory and laboratory use and makes a wide range of
applications possible. Together with a control instrument that is able
to set parallel remote lines, the 731 Relay Box allows the individual
switching of instruments that have no communication interfaces of
their own.
Thanks to the adjustable output level of the low-voltage direct
current outputs a wide range of instruments can be powered and
switched.
This means that you are able to assemble your laboratory
automation system according to your specific requirements.
1.2 Possible applications
The 731 Relay Box can be controlled by any Metrohm instrument (or
by an instrument from other manufacturers) that possesses a remote
output whose output lines (TTL level, 5 volt) can be set freely (e. g.
726 Titroprocessor, 730 Sample Changer, 711 Liquino) or which can
be set so that they are automatically event-controlled during a
method run (e.g. Titrinos, Metrohm pH meters).
Via the 230/110 volt current sockets (AC1 and AC2), instruments
such as pumps, heaters, coolers can be supplied with electricity.
Instruments that require a direct current supply voltage of between 5
and 24 volts or that can be controlled by voltage pulses, e.g. pumps
or Dosimats, can be connected to the low voltage direct current
outputs (DC1 and DC2).
