Product Features
The CAS200 is a modular monitoring system with 16 analog inputs. It can function as a stand-alone system; the CAS200 1/8 DIN front panel has a Vacuum Fluorescent Display (VFD) and touch keypad for local display and local parameter entry. You can also use it as the key element in a computer-supervised data acquisition system; the CAS200 can be locally or remotely controlled via an EIA/ TIA-232 or EIA/TIA-485 serial communications interface.

Features include:
Direct Connection of Mixed Thermocouple Sensors
Connect most thermocouples to the scanner with no hardware modifications. Thermocouple inputs feature reference junction compensation, linearization, process variable offset calibration to correct for sensor inaccuracies, detection of broken, shorted, or reversed thermocouples, and a choice of Fahrenheit or Celsius display.
Automatic Scaling for Linear Analog Inputs:
The CAS200 series automatically scales linear inputs used with industrial process sensors. Enter two points, and all input values are automatically scaled in your units. Scaling resistors must be installed.
Flexible Alarm Outputs:Independently set high/low process alarms and a high/low deviation band alarm for each channel. Alarms can activate a digital output by themselves, or they can be grouped with other alarms to activate an output.
Alarm Outputs:You can set high/low deviation and high/low process alarm setpoints to operate digital outputs as latched or unlatched functions.
Global Alarm Output:When any alarm is triggered, the global alarm output is also triggered, and it stays on until you acknowledge it.
CPU Watchdog:The CAS200 series CPU watchdog timer output notifies you of system failure. Use it to hold a relay closed while the system is running, so you are notified if the microprocessor shuts down.
Front Panel or Computer Operation:Set up and run the scanner from the front panel or from a local or remote computer. Watlow Anafaze offers WatView, a Windows® compatible Human Machine Interface (HMI) software package that includes data logging and graphing features in addition to process monitoring and parameter setup screens.
Multiple Job Storage:Store up to eight jobs in protected memory, and access them locally by entering a single job number or remotely via digital inputs. Each job is a set of alarm conditions.
Pulse Counter Input: Use the pulse counter input for precise monitoring of motor or belt speed.

Mounting Scanner Component
Install the scanner in a location free from excessive heat(>50°C), dust, and unauthorized handling. Electromagnetic and radio frequency interference can induce noise on sensor wiring. Select locations for the CAS200 and TB50 such that wiring can be routed clear of sources of interference such as high voltage wires, power switching devices, and motors.
