GENERAL:

The CWM-EFM-2 is an enclosed device that employs a scalable, modular hardware design. Units contain a base backplane that supports 2 or 6 I/O modules. An expansion backplane can be added to the base backplane providing an additional 2, 4 or 8 I/O Modules. Each ControlWave Micro Process

Automation Controller is comprised of a Backplane Board (mounted in the

Chassis), a Power Supply Module, a CPU Module and from 0 to 14 I/O modules.

All system modules plug into the Backplane Board (2 I-O slot base, 6 I-O slot base, or 2, 4, 8 I/O expansion backplanes). Each I/O Module provides the circuitry and field interface hardware necessary to interconnect the assigned field I/O circuits. CPU Board implements a 6 status LEDS. Power is generated and regulated by the Power Supply/Sequencer Module that provides

+3.3 V dc. The digital input isolated card provides an isolated 21 VDC for contact closure.

The CWM-GFC-2 is a scaled down version of the CWM-EFM-2.

The CWM-GFC-T4, Control Wave Express PAC, and CW-Express are scaled down, cost-effective versions of the CWM-GFC-2, with identical differential/gauge pressure ranges, power systems, RTD, RTD Thermowell options, RF Communication options, and RF Radio options as the CWM-GFC-2.

The three models have identical I/O Modules. The CWM-GFC-T4 and Control Wave

Express PAC are housed in identical enclosures as the CWM-GFC-2 and are similar except for a CPU option on the Control Wave Express PAC and differential/gauge pressure sensors (wet end) on the CWM-GFC-T4. The CW-

Express has an identical CPU option as the Control Wave Express PAC, but is an open-type device and housed in a sheet metal enclosure.

The CWM-GFC-T4P uses the electronics of the CWM-GFC-T4 with the enclosure and power systems of the CWM-EFM-2.

The CWM-GFC-TC is similar in design to the CWM-GFC-T2. The CWM-GFC-TC employs a gauge pressure sensor similar to the one used on the CWM-GFC-T2 except for the presence of one sensor on the transducer instead of two, the absence of a differential chip, and a ½” female NPT process connection instead of a ½” male NPT process connection. The CWM-GFC-TC also employs a pulse counter.
