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

Module Installation

!

WARNING: Remove power from the controller before changing the output module. Failure to do so could cause damage to controller and/or personal injury or death from electrical shock.

When handling output modules, be careful to guard the module against static discharge. Follow the steps below to remove an existing output module and replace it with a new module.

Removal

1.	Remove power from the controller.
2.	Remove all terminal connections.	continued
