Type Programmable Single-Loop Controller
Programming FBD (Function Block Diagram) language. Includes function blocks for PID control, arithmetic, logic, timers, counters, and more.
Display • Type: Backlit LCD with bargraph
• Primary Display (PV): Shows process value
• Secondary Display (SV): Shows setpoint or other parameters
Inputs (Built-in) • Analog Input (AI): 1 point. Typically universal, accepting thermocouple (T/C), RTD, DC voltage, and DC current (4-20mA) signals (software-selectable).
• Digital Inputs (DI): 4 points. For contact inputs, status signals, or interrupts.
Outputs (Built-in) • Analog Output (AO): 1 point. Typically 4 to 20 mA DC.
• Digital Outputs (DO): 2 points. Relay outputs (common rating: 250V AC, 2A).
