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 controller 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
solenoids 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 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.
Y 5 A (120/240 Vac) relay, but normally closed (output 2 only).
