Introduces the characteristics of the IQM type electric actuator, including power supply voltage, performance, solid state starter, dynamic braking, etc.
This document provides the technical specifications and control/monitoring facilities for Rotork's IQM and IQML actuator series. It covers supply requirements, performance limits, solid‑state starter design, dynamic braking, positional accuracy and power fuse recommendations.
The manual also describes optional add‑on modules such as the Folomatic analogue controller, Current Position Transmitter, alarm relays, and the IQ Setting Tool for remote configuration via infrared. Wiring diagrams, circuit options and dimension data are included to aid installation and commissioning.
| Maximum supply voltage | 480 V, 50/60 Hz |
|---|---|
| Minimum supply voltage (IQM30) | 380 V, 50/60 Hz |
| Positional accuracy (repeatability) | 0.1 output turns |
| Rated current IQM10‑IQM20 | 10 A |
| Suggested power fuse IQM10‑IQM20 | Ferraz G3300 |
| Suggested power fuse IQM25‑IQM35 | Ferraz K3300 |
The actuators can be supplied with up to 480 V at 50/60 Hz.
The minimum pulse length is 18 ms and the minimum interval between pulses is 500 ms.
The Folomatic controller enables analogue current or voltage control of the valve position.
The Rotork IQ Setting Tool can read and set all actuator functions via an infrared receiver.
