4.3 Timing M/R module
The Timing M/R module measures timing on Main
and Resistive (parallel) contacts. The module measures
up to six breaks with both main and resistive contact,
giving in total 12 measuring channels. The TM1800
system can be equipped with multiple Timing M/R
modules that enable any type of test setup to be per-
formed. All three connectors (phases) are galvanically
isolated and have built-in voltage source.
For specifications, see “Timing M/R Module” in chap-
ter 9 Specifications.
Terminal configuration
The module is equipped with three XLR female con-
nectors on the front grouped in phase sections named
A, B and C. Each connector has three pins for connec-
tion to two breaks.
1 First break point
2 Second break point
0 Common point for both breaks
