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.
