Modular, Powerful Multi-Loop Temperature and Process Control

The Watlow SERIES MLS300 is a powerful line of controllers that combines performance and flexibility with compact design. The 16 and 32 loop versions provide complete control solutions for a broad range of applications. Each controller includes built-in serial communications. Optional features include programmable ramp and soak profiling, cascade control and process variable retransmit. The SERIES MLS300 controllers are UL® and C-UL® listed and carry the CE mark.

Applications

• Electronics and semiconductor equipment
• Life sciences
• Packaging
• Plastics processing
• Processing industries
• Food processing

Firmware Options

• Standard—PID control, auto-tune, alarms, job memory, and failed sensor detection.
• Extruder—PID control specifically adapted for plastic extruders.
• Ramp and Soak—standard features plus ramp and soak profile programming and process variable retransmit. Configure each channel for PID control or ramp and soak. Use any spare control output for retransmit.
• Enhanced Features—standard features plus process variable retransmit, remote analog set point, cascade control, ratio control and differential control algorithms. Configure each channel for any algorithm. Each cascade and remote analog set point channel requires two analog inputs. Use any spare control output for retransmit.

Process variable retransmit requires one SDAC module per retransmitted signal.

Input Module Options

• AIM316 and AIM332 provide screw terminations for 16 or 32 sensors
• CIM316 and CIM332 provide DB-50 connector terminations for 16 or 32 sensors in a compact size

 

 

Advanced, closed-loop PID control of up to 16 heat and cool loops or 32 heat loops	Minimal panel space per loop Reduced installation time More reliable: fewer parts means fewer failures
Simple auto-tune	Less time tuning Excellent control with less expertise
Menu-guided operation with full text display	Fast controller set up Easy to operate
Eight jobs stored and recalled	Quick to change from one process to another
Multiple and mixed inputs including thermocouples, RTDs, linear voltage, current and frequency	Easy to change sensor types at the last minute Less to learn Less inventory
Sensor failure detection	Reduced time troubleshooting
High/low process and deviation alarms for each input	Configure alarms as needed to integrate with PLC or other control elements
34 flexible digital outputs	Use as needed for control and alarms
EIA/TIA-232 and 485 communications	Use software to configure and operate Data acquisition Integrate with other controllers and software
Remote analog inputs provide flexibility in mounting	Reduces sensor cost by moving terminations closer to process Reduces installation time when sensors do not have to be brought all the way to the control enclosure
Mass termination of sensors (CIM300 option)	Small footprint per loop requires less panel space Reduces installation time
