HARSH ENVIRONMENT CONTROLLER WITH LADDER LOGIC PROGRAMMING

Divelbiss Corporation, providing cost-effective customized solutions to standard industrial automation and control problems since 1974, announces the HEC-1000 Harsh Environment Controller based on PLC on a ChipT technology. The HEC-1000 Harsh Environment Controller allows for programmable intelligence under less than ideal conditions due to a sealed, water-tight enclosure with pluggable connectors. The standard enclosure is submersible to three feet and is screw and sub-plate mountable. The HEC-1000 is programmed using Divelbiss EZ Ladder software which supports ladder diagram and function block programming. The HEC-1000 Harsh Environment Controller features 12 to 26.4 VDC input power. I/O includes 10-32 VDC inputs; two 40 kHz high-speed counters; two 10-bit resolution 0-20mADC analog inputs; and PWM/digital outputs rated to three amps with automatic over-current safety and programmable status monitoring for each. Network communication is accomplished via two CAN ports; one of which is dedicated J1939. Expansion I/O includes both digital and analog with allowance for future custom modules as required. The HEC-1000 Harsh Environment Controller also includes a RTC (Real Time Clock) with skip-a-day capability that allows the program to deal with hour, minute, second, month, day, year and day of week. Typical industrial use includes control for engine driven pumps and compressors, mobile asset management and tracking, intelligent mining or oil field equipment, conveyor systems, and marine application. The 12 to 26.4 VDC input power is particularly useful for ease in utilization by off-highway platforms.
