The Built-in Microprocessor Based Circuitry Accepts Milliamp, Volt &
Resistance Input Signals. One Unit Does It All!

优点：
• 90° or 180° stroke, switch selectable
• One mA and three VDC input ranges
• Potentiometer input, 100 to 1000 ohms
• Control overrides for either direction of travel
• Field configurable direction of travel
• NEMA 4 housing standard on most models

节省费用 以一当十

Rapid delivery can be so critical in those “down” situations. The versatility of the analog circuit means that one unit can replace several of the older models. Switch selectable input circuitry accepts current, voltage or resistance input signals. All of the analog input actuators are manufactured for a 180°stroke. Flip a switch and it becomes a 90°actuator. Need a custom stroke? 15 turn zero and span trimpots allow you to set any stroke length from 60°to 180°. Need to change the direction of travel? A simple procedure in configuration mode will do it. No wiring changes required.

Reliability is assured by the use of high temperature rated components. Every item is rated for continuous operation at a temperature of 105°C. Some components are rated much higher. Plastic safety barriers on the mains terminal strip and over a portion of the circuit board provide protection against shock hazard during installation.
