Specifications are subject to change without prior noticeCA20 |Introduction
Developed primarily for the healthcare sector, the analogue control
box CA20 is a compact solution optimised for flexible integration andmounting.
With built-in Switch Mode Power Supply (SMPS), the CA20 delivers 90 W
with four channels and a hand control port. This lightweight control box
represents value for money when applications require a simple, streamlinedsolution.
The CA20 has an elegant design and offers a choice of mounting options. By using screws or designatedbracket, it can be attached directly to the application and on the LA27 actuator using the unique slide-onbracket.
Via inbuilt signal switches, the CA20 communicates directly with the actuator, which means that motor
power is being cut off at the control box rather than the actuator is using power switches.
