40 Channel Analogue or
Digital Output FTA
Introduction
The TrustedTM 40 Channel Analogue Output or Digital Output FTA is designed to act as the main
interface between the TrustedTM TMR 24V dc Digital Output Module T8451 or TrustedTM TMR
Analogue Output Module T8480 and TrustedTM the field device. The signal from the output modules
are 24V dc and 0-20mA respectively.
Features
• 40 output channels per FTA.
• Industry standard field device connections (2-wire).
• Standard DIN rail compatibility.
• Screw clamp terminals on both field and power.
• Simple installation and connection.
• 24V dc operation.
• SmartSlot connection for ‘one to many’ hot replacement of output modules.
• Field power supply arranged in five groups of eight channels, with OV
isolation between groups.
• On-board LED indication field power supply integrity.
• Field terminal wire size allowance 12 to 28 AWG

Figure 2 Two Channel Schematic
Indication of of the presence of the field power supply is provided by a green LED (one for each power
group). The supply is then fed to each channel within the power group.
The signal to the field device is fed directly from the output module.
The cable linking the 40 channels on the output module to the FTA is terminated at the 96-way socket
SK1. SmartSlot (Version 1) signals from the module are connected to SK1. The dc field power
supplies can be connected to the FTA via a 10-way terminal block PWR TB. The output signals to the
field (40-off) are connected by 2-wire arrangements terminated on the dual height terminal blocks.
