8 lines are available for signal output (Output 0-7). The remote socket of the

717 Sample changer has 14 output lines available (Output 0-13).

For receiving signals (e.g. the "ready" signal from a Metrohm instrument)

there are 8 lines available (Input 0-7).

The control lines of the 726 Titroprocessor are purely signal leads (TTL-level)

and should not be misused for supplying devices.

Remote connections can be used with specially assembled cables to solve

complex connection problems in automated systems.

Connection of Metrohm instruments is solved in the following manner with

For the individual model series of Metrohm instruments different connection

cables are available with which the specific functions of the particular in-

strument can be addressed. On request Metrohm can supply special ca-

bles in accordance with the customer's wishes with which complex connec-

tions can be made (even to instruments from other manufacturers).

Output lines 8…13 can only be used

with the 717 Sample changer, but are

not used as input lines for Metrohm in-

struments. They are laid 1:1 on Pin

6…8,13,19…20.
