The Chameleon Process Control Module (PCM-1+) offers high-performance control for multiple process loops.  With four analog inputs, four analog outputs, two digital inputs, two digital outputs, and an on-board 24VDC auxiliary output source, a PCM-1+ can regulate up to six independent loops (4 process loops and 2 digital/motor control loops).  It is powered by a modern cyber-secure processor with computational power to handle the most demanding applications.  The PCM-1+ embedded firmware is stored in its flash memory and is upgradeable: you can rest assured that the hardware investment you make in Chameleon will not become obsolete.

Using Fairmount Automation’s intuitive and easy-to-use graphical programming package (Design Pad G5) you can develop sophisticated control schemes for the PCM-1 in a matter of hours—even without any prior programming experience.  Programming the device entails “drawing” a desired control scheme using a vast array of configurable function blocks.  These function blocks are wired together to indicate the signal flows from device inputs to device outputs.  Once complete, configuration programs are downloaded to the unit via a wireless IR interface.

The PCM-1+ provides a versatile I/O suite configurable in software.  Its analog inputs can read a variety of signals, including voltage, current, resistance, and RTD.  Its analog outputs can drive voltage and current loads.  Its digital inputs can be used separately as switches, pulse counters, and frequency counters, or they can be used together for event timing and quadrature decoding.  Its digital outputs can generate on/off, variable frequency square wave, and pulse-width modulated (PWM) signals.  In addition, multiple PCM-1+ units can be attached to each other and configured to provide redundant power and I/O connections (both inputs and outputs) – the redundant output capability is built-in hardware and requires no external hardware.   PCM-1+ units are also hot swappable: to replace one, simply swap the front panel (with attached processing board) and the unit is back online—there is no need to shut off the power.

Each PCM-1+ unit also provides a rich set of prominent displays, including four four-digit numeric displays and eight status-indication LEDs.  Each display set has an associated tag holder that you can use to label signals.

As with all Chameleon modules, the PCM-1+ offers unequaled ruggedness.  It is specifically designed for sustained operation in severe environments, including those characterized by extreme shock, vibration, electro-magnetic interference, temperature, and/or humidity.  Its fully-sealed enclosure (sealing end-caps not pictured) ensures long-lasting operation in the grimiest settings.  In fact, Chameleon modules can operate fully submerged.
