FPAS(M)
Freeze Protection
Ambient Sensing
(Monitoring) Series
The FPAS series controls multiple heat trace cir-
cuits via an ambient sensing external thermostat,
external electronic controller or via an ambient
sensing, door mounted 6040 DIN controller.
Chromalox recommended controllers include:
RTAS, RTAS-EP, B100, E100 or the 6040 DIN
controller. NEMA 4/4X options available.
PK557
FPLS(M)
Freeze Protection
Line Sensing
(Monitoring) Series
The FPLS series controls each heat trace line
with individual Chromalox RTBC, RTBC-EP,
E-100 or E121 line sensing controls. Each circuit
should be controlled by an individual sensor/
controller. Depending on the application, control-
lers can switch more than one circuit. NEMA
4/4X options available.
PK557
RSP
IntelliTrace Remote
Sensor Panel
NEMA 4 Painted Steel, NEMA 4X Fiberglass or
NEMA 4X 305SS enclosure. Fully integrated
package that consolidates up to 252 temperature
sensor signals in a single enclosure. Works
seamlessly with the Chromalox IntelliTrace ITLS/
ITAS heat trace control panels.
PK497
DTS-HAZ
Heat Trace Digital
Thermostat
The DTS-HAZ digital thermostat is a NEMA 4X
rated power connection kit and microprocessor-
based temperature control. It is used for freeze
protection or process temperature maintenance
of pipes or tanks protected by heat tracing prod-
ucts.
