1. FUNCTIONAL DESCRIPTIONS
All models feature a water proof & corrosion resistant IP65/NEMA
4X enclosure for bench or surface mounting. The CTCII is a
compact 4.7” (120mm) x 6.3” (160mm).
Bright dual GREEN/RED LED indicates ON/OFF (above or below
set point). All models feature TWO heavy-duty 10 amp output
relays, operating on increasing concentrations.
All models include input power cord* (115 VAC powercord 8 ft.
with USA 3 prong plug - NOT for use with 230 VAC), two (2)
output power connectors, CSAR sensor, and appropriate strain
reliefs.
The CS51R sensor for more demanding applications may be
substituted at an additional cost.
For specific CTCII configurations, reference the following
individual model descriptions.
*NOTE: for 230 VAC or other power requirements the plug must
be cut off or removed and hard wired directly to the source or a
local plug or adapter may be installed.
