Controller Components
I/O modules
Eleven different module types can be installed in the controller to support both analog and digital inputs
and outputs of various types and signal levels. The signal type and I/O capacity for each module type is
indicated in Table 1.
Module Type
Universal Analog Inputs (AI)
Analog Outputs (AO)
Digital Inputs (DI) - 4 types:
AC
DC
Logic
16 point
Digital Outputs (DO) - 4 types:
AC
AC
High current outputs
DC
Relay
Pulse Input/Frequency Input
pH Power Module
NOTE: Total combined digital I/O is 96 points.
Control architecture
The UMC800 uses a function block configuration architecture to develop control strategies for both analog
and digital operations. A function block may represent a physical input or output, a group of physical inputs
or outputs, an internal calculation, or an internal function such as a PID algorithm. More than 70 standard
UMC800 function block algorithm types are available for configuring analog and logic functions.
Typically, a function block algorithm type may be used any number of times up to the limit of 250 blocks.
Some of these with specific limitations are:
Control loops (i.e., PID, ON/OFF, TPSC, and Carbon potential)—eight or sixteen maximum
Setpoint programmer and associated support blocks—four maximum
Setpoint Scheduler and associated support blocks—one maximum
Time proportioning output blocks—sixteen maximum
Pushbutton blocks—four maximum
4 Selector Switch blocks—four maximum
Modbus Slave blocks—sixteen maximum
