PowerTune ®Functions PowerTune ® Adaptive Tune modifies PID parameters to eliminate oscillation or drift when load changes occur. Adaptive tune works automatically without disturbing the process. PowerTune ® Pretune gets process up and running quickly and accurately. Optimal pretune performance is achieved by selecting a pretune algorithm appropriate for your process. PowerTune ® Pretune automatically sets: 1) Initial PID parameters 2) Adaptive Tuning parameters 3) Powerback parameters ➤ Four Field changeable output module locations (MA, Relay, SSR, DC, Logic, Loop Power) Rugged...

INPUT FUNCTIONS PROCESS VARIABLE Two universal inputs are available. Any input type may be field selected via jumper. Thermocouple and RTD inputs are automatically linearized. Transmitter inputs may be linearized with a square root function or user-defineable 15-point straight line linearization function. Current Input: 250 ohms Voltage Input: 1 Mohm Transmitter Signals Milliamps DC Voltage DC Millivolts DC Themocouple: 10 Mohms RTDs: 10 Mohms UPDATE RATE Input is sampled and output updated 10 times per second. Display is updated five times per second. TRANSMITTER LOOP POWER Isolated 24Vdc...

OUTPUT FUNCTIONS Manual Rest/Load Line: 0 to 100% output OUTPUT MODULES The controller can have a total of four control outputs, alarm outputs and/or loop power modules installed. There are five types of output modules which can be configured to suit your particular application. The modules may be ordered factory-installed, or they may be installed in the field. Cycle Time: 0.3 to 120 seconds Analog module: Either 0–20mA or 4–20mA (front panel selectable) into a load up to 1000 ohms. Accuracy ± 5µA @ 25°C. Mechanical relay module: SPDT electromechanical relay. Resistive load rated at 5 amps...

GENERAL SPECIFICATIONS CONTROLLER ARCHITECTURE The 545 Controller hardware can be configured as follows: Inputs: Two universal process variable inputs are standard. Available options include: remote setpoint, slidewire feedback and 5 digit inputs. Outputs: Four outputs are available See Ordering Information. RS-485 Communications: Available as option with any configuration. SERIAL COMMUNICATIONS Isolated serial communications is available using an RS-485 interface. Baud rates of up to 19,200 are selectable. The protocol supports CRC data checking. If communications is lost, a timeout...

AGENCY APPROVALS LISTED Process Control Equipment 4N66 (Heavy Industrial) (Available as an Option) SECURITY There are two levels of access: restricted and full. A configurable code is used to enter the full access level. Functions not available in the restricted level are configurable. MEMORY RETENTION Lithium battery maintains all programming for approximately ten years.
