MLS300: Modular
Loop System
Providing up to
32 Zones of Control
The Watlow Anafaze MLS300 SERIES 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.
Support for multiple types of sensor inputs is available;
including thermocouples, RTDs, linear voltage, current and
frequency. Each controller can operate as a stand-alone
system, and includes built-in serial communications for
computer interface and data acquisition. Optional,
programmable ramp and soak features allow complex
batch processing and sequencing. The enhanced
features option offers cascade, ratio and differential control,
process variable retransmit and remote analog setpoint.
The remote analog input options allow for shorter sensor
wires and flexible mounting which reduces sensor cost and
installation time. Watlow’s new CIM option provides OEMs
with a space and labor saving alternative to the standard
AIM module. This innovation allows users to construct a
wiring harness to attach sensors via a connector instead of
connecting individual wires to the controller.
The MLS300 SERIES controllers are UL
®
and C-UL
®
listed,
meet the requirements of the European Community EMC
Directive and carry the CE mark.
