WARNINGS AND CAUTIONS

WARNING: EXPLOSION RISK

Do not connect or disconnect equipment while the circuit is live or unless the area is

known to be free of ignitable concentrations or equivalent

AVERTISSEMENT - RISQUE D’EXPLOSION

Ne pas connecter ou déconnecter l’équipement alors qu’il est sous tension, sauf si

l’environnement est exempt de concentrations inflammables ou équivalente

MAINTENANCE

Maintenance must be carried out only by qualified personnel. Failure to follow these

instructions may result in personal injury.

CAUTION: RADIO FREQUENCY INTERFERENCE

Most electronic equipment is influenced by Radio Frequency Interference. Caution

should be exercised with regard to the use of portable communications equipment

around such equipment. Signs should be posted in the vicinity of the equipment

cautioning against the use of portable communications equipment.

CAUTION:

1. Description

Figure 1 T8871 Photo

The Trusted 16 Channel 120 Vac Digital Output FTA T8871 provides termination for a

maximum of 16 output channels. Figure 2 below shows the configuration of a single

channel.

Figure 2 Single Channel Schematic

The supply for the field is connected via terminal blocks TB2 (Group 1) and TB4 (Group 2) on

the FTA. This is supplied to the module on sockets SK2 and SK4 via harmonic and transient

protective devices as shown.

The output signals to the field (16-off) are connected from the module on sockets SK1 and

SK3. TB1 and TB3 provide screw terminals for field wiring.
