Key Benefits of Ladder Logic Controllers (used for control of items other
than compressors, condensers and evaporators):
LL1632 Ladder Logic Controller Module
Ladder Logic Module can be used for miscellaneous control needs, such as pump packages,
lighting, floor warming, heat exchangers, battery chargers, water chemistry
control, etc.
Has 16 digital inputs and 32 analog inputs, which can be used to control 32 digital outputs.
Ladder logic programming also can use counting, time delays and time-of-day in logic.
Ladder logic can use separately displayed and adjustable set points in logic.
Logic is written in easy-to-use English language tables.
Six pages of logic tables are available in password protected region.
32 internal flags and 16 counters are also available for use in logic.
LL3216 Ladder Logic Controller Module
The LL3216 Ladder Logic Module is the same as the LL1632 described above, except that
there are 16 digital inputs instead of 32; and there are 32 digital outputs instead of 16.
LLPID Ladder Logic Controller Module
The LLPID Ladder Logic Controller is identical with the LL1632 Ladder Logic module,
except that it also has 16 analog outputs, each with a PID loop which can be used to control
variable speed drives, regulating valves, or other devices which require an analog input
for control.
Can control with voltage (0-5V, 0-10V) or current (4-20mA).
Output can be specified as a fixed amount by the operator, if needed.
Analog output can be set to increase or decrease with the control parameter.
