Unitronics' Jazz 2 Series JZ20-R16 and JZ20-R10 Controllers
Jazz 2 Series JZ20-R16 and JZ20-R10 controllers are backward-compatible, have 48K (virtual) Ladder Logic memory, built-in mini USB programming port, and include four auto-tune PID loops. PID can be set using the onboard temperature/analog inputs, and the analog or PWM outputs; all onboard transistor outputs can function as PWM outputs. A full-function HMI with a two line LCD text display shows up to 60 user-designed screens. Communications include SMS messaging, Modbus, and PC access via Modbus or OPC.
