Integration with existing process-control systems is through an isolated 4-to-20-mA input/output signal.
Standard features include 1/50 to 2.0-hp range, universal power supply supports 85 to 265-Vac input, 1/8 or …-DIN panel mount with NEMA-4X faceplate, or NEMA-4 stand-alone enclosure, and front-panel field-programming (with lock-out jumper). Target and actual speed can be any engineering unit of measure. There are two alarm-relay outputs (form C, 5 A @ 250 Vac), a large -in. LED display, master/follower modes, and the unit displays setpoint or actual running speed.
