June 2, 2011 - Divelbiss announces the HEC-1500-E-R extended temperature range (-40° to +80°C) Harsh Environment Controller. Based on PLC on a Chip technology, the HEC-1500-E-R Harsh Environment Controller allows for programmable intelligence under less than ideal conditions due to a sealed, water-tight enclosure with plug connections. The standard enclosure is submersible to three feet and is screw and sub-plate mountable. The HEC-1500-E-R is programmed using Divelbiss EZ Ladder software which supports ladder diagram with function block programming. The HEC-1500-E-R Harsh Environment Controller features 8 to 32VDC input power.
I/O includes six (6) 8-32 VDC inputs - two (2) of which are independently field selectable for sinking or sourcing in addition to providing 40 kHz high-speed counting ; two 10-bit analog channels field selectable for 0-5VDC, 0-10VDC, or 0 to 20mA; and six (6) digital/PWM outputs rated to four (4) amps with automatic over-current safety and programmable status monitoring for each. Network communication is accomplished via the CAN port (J1939 capable) or by means of a serial communication port which is field selectable for RS-232, RS-422, or RS-485 configuration. Typical industrial use includes control for engine driven pumps and compressors, spreaders, diesel powered mining equipment, agriculture, forestry, and marine application.
The 8 to 32 VDC input power and wide operating temperature range ( -40° to +80° C ) is particularly useful for ease in utilization by off-highway platforms and outdoor applications where extreme ambient temperatures are the norm.
