Introduction
The Trusted
T

Speed Monitor Output Field Termination Assembly (SOFTA) is a DIN rail mounted
piece of equipment. It provides the output field interface for one rotating machine group when used as
part of a Trusted
TM
T8442 TMR Speed Monitor system.
Both normally open and normally closed volt free contacts are available on the field terminals. This
allows the SOFTA to be used in energised to trip and de-energised to trip configurations. .
The two relay output channels are arranged as quad redundant, fault tolerant structures. Failure of any
one relay or contact will not affect the load, or the ability to control the load.
Load current feedback to the T8442 Speed Monitor is provided for each switching path on each
channel.
Force guided contact safety relays are used. These allow the T8442 Speed Monitor to detect welded or
stuck output contacts via the contact status and load current feedback from the SOFTA.
Each relay, fuse and current-sensor can be replaced in situ.
Features
Two online tested, fault tolerant, volt free contact output channels
Each output can be used as either a normally open or a normally closed contact.
Fault tolerant quad redundant output relay structure.
Load feedback monitoring.
Contact status feedback.
Force guided contact, safety relays.
Standard DIN Rail mounting
Each output rated
Relays, fuses and current sensors can all be replaced in situ.
