Output Type
Description
R
5 A (120/240 Vac) relay, normally open,
used for switching resistive loads. If an “R”
output is selected, order CNQUENCHARC. If
relays or solenoids are to be driven, select
the “T” output.
DC
20 Vdc pulsed output for solid-state relays.
T
1 A @ 120/240 Vac, solid-state relay, zero
voltage-switched and optically isolated from
drive signal. Only resistive loads to 1A may
be controlled directly. Larger loads may be
controlled using an external contactor.
F
4-20 mA, full output to load with 500 ohm
impedance max. (suppressed).
FH
High impedance 4-20 mA (1000 ohm max).

Output Types
The Type “R” output
is a mechanical device
and subject to wear.
To extend the life of
the relay, set the Cycle
Time for the relay
output to the longest
duration that still
affords good control.
When you ordered your Series CN8200 controller specific
output types were specified, designated as “R”, “DC”, “T”,
“F”, or “FH”. You also had the option of configuring your
controller with either one or two output actions. The numbers
below are suggested for most typical applications.

*“T” outputs directly driving non-inductive loads (small heaters) can have
cycle times as low as 0.2 seconds.
