Red Lion - Model T48/P48 -PID Controller

Alarms:
Optional alarms can be configured to activate according to a variety of actions (absolute high or low, deviation high or low, 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 and 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 independently of the input range. The T48 optional heater current monitor provides a direct readout of process heater current and can be associated to an alarm to signal prior to heater failure.

Remote Communications:
A remote setpoint input (4 to 20 mA) allows for cascade control loops, where tighter control quality is required; and allows for remotely driven setpoint signals from computers or other similar equipment. Straight forward end point scaling with independent filtering and local/remote transfer options expand the controller’s flexibility. The optional RS-485 serial communication interface provides two-way communication between a controller and other compatible equipment such as PLC, HMI, printer, or host computer. In multipoint applications (up to 32), 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. Crimson® software allows for easy configuration of controller parameters. These settings can be saved for later use or used for multi-controller down loading.
