Output Type Description
B5A/3A (120/240 Vac) relay, normally
open, used for switching resistive loads. If
relays or solenoids are to be driven, select
the “T” output. If a “B” output is selected,
order snubber network 235Z005U01.
E0-20 mA
F4-20 mA, full output to load with 500 ohm
impedance max. (suppressed).
S20 Vdc pulsed output for solid-state relays.
T1A @ 120/240 Vac , solid-state relay, zero
voltage-switched and optically isolated from
drive signal. Only resistive loads to
may be controlled directly. Larger loads
may be controlled using an external
contactor.
Y5A/3A (120/240 Vac) relay, but normally
closed (output 2 only).
Operation
Athena Series 16 Universal Controller
The Series 16 is a full-function, autotuning PID controller,
calibrated and pre-configured for your application require-
ments, according to the ordering code specified, either as a
temperature or linear process controller. (See page 39 for
specifications and ordering code).
Just a few easy steps are required before the instrument can
be placed into service. After completing the mounting and
wiring procedures as previously instructed, set your individ-
ual process parameter values by stepping through the Series
16’s setup menus, using the simple front-panel keys as
instructed. Then, initiate the autotuning sequence as shown
(or tune manually).
Notes on Outputs
When you ordered your Series 16 controller, a specific output
type was specified, designated as either “B”, “E”, “F”, “S”,
“T” or “Y”. You also had the option of configuring your
controller with either one or two output actions. Generally,
output 1 is a heat (reverse-acting) function and output 2 is a
cool (direct-acting) function. For best results, follow the
recommendations for setting cycle times for the output type
supplied with your controller. A brief description of output
types follows:
