They can be used for on/off and proportional control; the proportional models have 4-20mA or 2-10vdc feedback output port. It has a lightweight, aluminum alloy enclosure that is electrostatic coated to provide NEMA 4/4X/IP67 and Class B motor protection. The auto-ranging power supply is compatible with 24 VAC/VDC or 85 to 265 VAC for on/off and proportional control. The 39" long power cable facilitates field connections with a PG6 EMT entry port having a sealed cable gland.
