Output Types
The Type “B” 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 C controller specific output
types were specified, designated as “B”, “E”, “F”, “G”, “S”,
“T” or “Y”. You also had the option of configuring your con-
troller with either one or two output actions. The numbers
below are suggested for most typical applications.
For Control Output Type — Select Cycle Time
(in seconds)
B >15
E 0.2
F 0.2
G 0.2
S 0.2
T 15*
Y >15
* “T” outputs directly driving non-inductive loads (small heaters) can have
cycle times as low as 0.2 seconds.
Output Type Description
B 5 A (120/240 Vac) relay, normally open, used
for switching resistive loads. If relays or sole-
noids are to be driven, select the “T” output. If
a “B” output is selected, order snubber network
235Z005U01.
E 0-20 mA
F 4-20 mA, full output to load with 500 ohm
impedance max. (suppressed).
G High impedance ‘F’ (800 ohms).
S 20 Vdc pulsed output for solid-state relays.
T 1 A @ 120/240 Vac, solid-state relay, zero volt-
age-switched and optically isolated from drive
signal. Only resistive loads to 1A may be con-
trolled directly. Larger loads may be controlled
using an external contactor.
Y 5 A (120/240 Vac) relay, but normally
closed (output 2 only).
