Based on the patented PLC-on-a-Chip technology, the HEC-HMI series controller allows programmable intelligence under lesser ideal conditions thanks to a water-tight enclosure with gland connectors. This standard enclosure is screw and sub-plate mountable, as well as sealed against the environment. The HEC-HMI series is programmed with Divelbiss EZ Ladder software that supports ladder diagram with function block programming.

The HEC-HMI series is offered as a HMI only or a HMI with Programmable Logic Controller (PLC) in the same enclosure. The entire series is available with an extended operating temperature range from -40°C to 80°C and 8VDC to 32VDC input power. A backlit LCD display is also offered in either 4 line by 20 character or 2 line by 16 character configurations. Character heights for the 2×16 and 4×20 options are 0.38” and 0.187”, respectively. Moreover, a total of four programmable indicators and nine pushbutton inputs are also provided. Four of the pushbuttons – in a horizontal row – are labeled as function keys, while the remaining five buttons are arranged in a compass pattern to be used as a joystick input. Network communication is achieved through a CAN port or a second serial communication port that is field configurable for RS323/422/485.

The HEC-HMI model series with integral PLCs integrate these additional features to the HMI only version. I/O includes six 8VDC to32VDC inputs (two are 200kHz high-speed counters) and six digital outputs with four rated to four amps with programmable status monitoring and automatic over-current safety. In addition, there are two analog inputs that can be individually configured to 0-5VDC or 0-20ma as required. Analog is offered in either 10- or 15-bit resolution.

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.
