HEC-HMI PLCs have a sealed, watertight enclosure with gland connectors, and an operating range of -40 to 80 °C. I/O provides six 8-32 Vdc inputs and two analog inputs field-configurable to 0–20 mA or 0–5 Vdc and available in 10- or 15-bit resolution. There are a total of six digital outputs. Four are rated to 4 A with automatic over-current safety and programmable status monitoring. These outputs are selectable as PWM with internal analog current-sensing variables to allow closed-loop control of the output loads.
