The Trusted @ Multi-Power Field Terminal Assembly (IFTA) T8842 is primarily designed to serve as the primary interface to field equipment for fire and gas detection and suppression and the trusted dual module TMR) area interface module T8448. It also acts as an interface to the trusted TMR valve monitoring module T8449, whose teaching word output to the solenoid valve is used alternately with the valve position analog input. Each channel of the VFTA is configurable to enable access to multiple field devices. These include devices that generate analog and digital input signals, as well as output devices that require up to 28 Vd for digital signals.
peculiarity
Each VFTA has 40 channels that can be configured as input or output
. Industry standard field device connections (2 or 3 wires).
. Standard DIN rail compatible.
Simple installation and connection.
Simple configuration using plug-in fuses and built-in resistors
Operation from 18vdc to 28vdc.
The on-site power supply is divided into 5 groups with 8 channels in each group
Select power from the controlled output of each group.
Melt field power supply for each channel.
