P4810101 Red Lion Controls 1/16 Din Process Control Units - w/Dual Relay, and Analog
The T48 Controller accepts signals from a variety of temperature sensors thermocouple or RTD elements, while the P48 Controller accepts either a 0 to 10 VDC or 0/4 to 20 mA DC input signal. Both controllers precisely display the process, and provide an accurate output control signal time proportional or linear DC to maintain a process at the desired control point. The controllers" comprehensive programming allows them to meet a wide variety of application requirements. The controller can operate in the PID control mode for both heating and cooling, with on-demand Auto-Tune, which will establish the tuning constants. The PID tuning constants may be fine-tuned by the operator at any time and then locked out from further modification. The controller employs a unique overshoot suppression feature, which allows the quickest response without excessive overshoot. Operation of the controller can be transferred to manual mode, providing the operator with direct control of the output. The controller may also be programmed to operate in the ON/OFF control mode with adjustable hysteresis. Dual 4-digit displays allow viewing of the process/temperature and setpoint simultaneously. Front panel indicators inform the operator of the controller and output status. The control output and the alarm outputs are field replaceable on select models. Optional alarm s can be configured to activate according to a variety of actions Absolute HI or LO, Deviation HI or LO, Band IN or OUT, and Heater Current Break with adjustable hysteresis. A standby feature suppresses the alarm during power-up until the process stabilizes outside the alarm region. Optional Main Linear DC output 10 V and 20 mA can be used for control or retransmission purposes. Programmable output update time reduces valve or actuator activity. The output range can be scaled independent of the input range. Optional Second Linear DC output 10 V or 20 mA provides an independent process retransmission, while the main Linear DC output is being used for control. The output range can be scaled independent of the input range. The T48 optional Heater Current Monitor provides a direct readout of process heater current. An alarm can be programmed to signal when the heater has failed. This provides early warning of system failure before product quality is affected. A Remote Setpoint input 0/4 to 20 mA allows for cascade control loops, where tighter control quality is required; and allows for remotely driven setpoint signal from computers or other similar equipment. Straightforward end point scaling with independent filtering and local/remote transfer option expands the controller"s flexibility. The optional RS485 serial communication interface provides two-way communication between a controller and other compatible equipment such as a printer, PLC, HMI, or a host computer. In multipoint applications up to thirty-two, the address number of each controller on the line can be programmed from 0 to 99. Data from the controller can be interrogated or changed, and alarm outputs may be reset by sending the proper command code via serial communications. PC software, SFCRM, allows for easy configuration of controller parameters. These settings can be saved to disk for later use or used for multi-controller down loading. On-line help is provided within the software. The unit is constructed of a lightweight, high impact plastic case with a tinted front panel. The front panel meets NEMA 4X/IP65 specifications when properly installed. Multiple units can be stacked horizontally or vertically. Modern surface-mount technology, extensive testing, plus high immunity to noise interference makes the controller extremely reliable in industrial environments
