Data Sheet • Mann Series U n i ve r s a l A u t o/ M a n u a l S t a t i o n AMS400A The AMS400A is an interface device used between controlling equipment and field devices to allow manual takeover of automatically controlled processes. Typical applications are: • manual start-up of sensitive processes before handover to automatic control • manual over-ride in case of controller failure or malfunction. A fully configured AMS400A can be installed in three I/O configurations, which interface between: • Analogue control equipment and analogue control devices • Digital control equipment and analogue control devices • Digital control equipment and digital control devices For analogue to analogue operation there are digital outputs available to force a change to automatic or manual mode. You can also set ramp rates and handover settings to ensure a smooth transfer of control. % \ Australia Weidmüller Pty Ltd. 43 Huntingwood Drive, Huntingwood NSW 2148 Phone +61 (0) 2 9671 9999 Fax +61 (0) 2 9671 9900 [email protected] www.mannseries.com United Kingdom Other countries Weidmüller Ltd. 1 Abbey Wood Road, Kings Hill West Malling, Kent ME19 4YT Phone +44 1732-877032 Fax +44 1732-873873 [email protected] www.weidmueller.com Weidmüller Interface GmbH & Co.
