6. Replacing Output Modules

The Chromalox 2110 Temperature Controller was 

shipped with the output modules installed as ordered. 

The 10A Solid State Relay and 20A Mechanical Re-

lay 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 2110 can be configured with a 1A Pilot Duty Relay 

or Solid State Relay Drive.

The 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.

Module Installation

Remove power from the controller before 

changing the output module. Failure to do so 

could cause damage to controller and/or per-

sonal injury or death from electrical shock.

When handling output modules, be careful to guard the 

module against static discharge. Follow the steps be-

low 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.
3.  Remove the back cover by lifting four housing clips 

on the controller. This releases the back cover. Then 

pull cover straight off the controller.

4.  Gently pry around the sides to loosen and remove 

the module. Pull module straight out to avoid bend-

ing pin connections.

Do not remove module by the handling compo-

nents on the module board. This could damage 

the module.

  When removing an S2 output module (SSR with 

fan), a cable connects the fan to the far right center 

of the S2 board. Gently disconnect the cable from 

the connector on the output board. 

Do not remove 

the fan from the back cover. This is a single as-

sembly.

  For the S2 output module, reconnect the fan cable 

to the connector on the far right center of the mod-

ule. Tuck the cable around the heatsink.

Replacement
1.  Line up pins on the controller with pin connections 

on either side of the module and push the new mod-

ule into place.

2. Reinstall the back cover.
