CN 2110 Temperature Controller
Section 6—Replacing Output Modules
Module Option Descriptions
The CN 2110 Temperature Controller was shipped with the output modules installed as ordered. The 10A Solid State Relay and 20A Mechanical Relay output cards control small cartridge heater or strip heater loads directly, eliminating the need for a remote contactor or solid state relay. If a larger load is required, the CN 2110 can be configured with a 1A Pilot Duty Relay or Solid State Relay Drive.
The CN 2110 may be optionally configured with a 5A/120V Alarm Relay. Alternate modules, configured with or without alarm, can be installed as needs change.
Control and alarm outputs can be changed in the field.
Output Module options are as follows
