Description
Watlow CLS216 105996005
Technical Specifications Total independent control loops:16; supported sensor inputs include multiple thermocouple types, platinum RTD, 4-20mA, 0-10V and frequency pulses; analog conversion precision 0.1% full scale; serial ports selectable EIA/TIA-232 or EIA/TIA-485 with termination jumper; operating ambient temperature -20 ℃ to +60 ℃; memory capacity for multiple ramp-and-soak batch recipes; optional 50-pin termination board with 3-foot SCSI interconnect cable.
Functional Features Dense multi-zone PID auto-tuning for synchronized thermal zones; enhanced algorithm option enables cascade control, ratio control, remote analog setpoint and process variable retransmission; nonvolatile recipe storage retains batch profiles through power loss; per-channel open-loop and over-range diagnostics; digital outputs can be mapped freely to any internal control loop.
Application Scenarios Continuous web drying ovens, composite autoclave multi-zone heating, solar cell manufacturing furnaces, multi-channel material thermal aging racks.
Material Composition Flame retardant plastic instrument housing; industrial FR4 PCB with conformal coating; high-density multiplexer signal chips; precision thin-film reference resistors; SCSI or screw-type field termination terminals.
Structural Characteristics 1/8 DIN panel mount package; front panel shared display and keypad for loop selection and adjustment; rear connector supports SCSI direct connection or 50-pin field terminal assembly; internal signal multiplexing architecture reduces external wiring quantity.
Working Principle Multiplexer circuits sequentially sample each sensor channel and feed measurements to ADC. The embedded processor runs sixteen separate PID loops simultaneously. Calculated output values drive solid-state relays or analog valve actuators. Serial communication services upload zone temperatures, alarm states and download batch recipes to host computers.
Installation Requirements Install in 1/8 DIN panel cutout; separate high-current heater wiring from low-level sensor cables; terminate communication bus resistor at physical cable endpoints; apply anti-static precautions during card replacement.
Operation Notes Load all batch recipe files to external storage before controller replacement; confirm jumper setting for signal mode before energizing instrument; inspect SCSI connector pins for corrosion in high-humidity plant environments.
