While the role of the heater control lop for the E-Series analyzers is basically unchanged from the previous version (see Figure 2-4) the configurability of the Thermocouple inputs has been enhanced. Previously, the two T/C inputs could be configured for either type-T or type-K thermocouples. The 04523 relay PCA adds the following.

∙Both T/C’s can now be configured as either grounded or ungrounded thermocouples.

∙Standard configuration of the both type of thermocouples is 10 mV/°C. In order to accommodate the M200EH’s Mini High-Con converter option, a type-K; 5mV/°C output configuration has been added.
