Divelbiss Corporation (www.divelbiss.com) announced its latest Programmable logic controller (“PLC”) in addition to the Harsh Environment Controllers family on a ChipT technology, the HEC-4000-E-R.

It is based on PLC-on-a-ChipT technology that allows programmable intelligence in less than ideal conditions because of its sealed and watertight enclosure with pluggable connectors. Its standard enclosure is submersible to 3-feet and is sub-plate and screw mountable. The HEC-4000 is programmed by using Divelbiss EZ Ladder software supporting the ladder diagram, which has a function block programming.

The HEC-4000-E-R features 8 to 32 Virtual Design and Construction (“VDC”) input power and an extended operating temperature ranging from -40 degrees to 80 degrees Celsius. Its I/O includes four 8 to 32 VDC inputs (“two are 40 kHz high-speed counters”); six digital outputs rated to four amps, including a programmable status monitoring and an automatic over-current safety. The four outputs are selectable as pulse-width modulation (“PWM”) with internal analog current sensing variables allowing closed loop control of the output loads. Also, there are four analog inputs factory set to 0 to 5 VDC or 0 to 20ma when recorded. Network communication is done by using a second serial communication port or via CAN port. Expansion I/O includes both analog and digital with required allowance for custom modules in the future.

Typical industrial use such as improved proportional valve control via marine application, conveyor systems, oil field equipment or intelligent mining, mobile asset tracking and management, closed loop, control for engine compressors and driven pumps. The wide operating temperature range (“-40 degrees to +80 degrees Celsius”) and 8 to 32 VDC input power gives ease particularly in utilization by marine platforms and off-highway.
