AC Interface Box
Overview
The EZ-SCREEN AC Interface Box (EZAC Series) is powered by 100-250V ac.
EZAC-R.. models can supply one EZ-SCREEN receiver, a single emitter-receiver pair, or two
cascaded emitter-receiver pairs; see Figure 4. Emitter-only models (EZAC-E..) can supply up
to four cascaded emitters, and have no output circuitry.
The integrated interface module, located on a replaceable PC-board, converts the
EZ-SCREEN receiver OSSD output signals into isolated redundant output channels with an
8 amp / 250V ac/dc switching capacity for ac or dc safety circuits (see Models on page 1 for
output descriptions). The outputs of the interface module follow the action of the EZ-SCREEN
OSSD outputs, with a 10 millisecond response time in turning OFF, and approximately 10
millisecond delay in turning ON. All models feature external device monitoring (EDM) in the
form of 1-Ch, 2-Ch or power monitoring.
All models have one 8-pin M12 Euro-style QD to connect to the EZ-SCREEN receiver or
emitter. Other connections are dependent on model; see page 1. Hookups, therefore, are also
model-dependent; see pages 6-9. See pages 14 and 15 for cabling options.
Indicators
A bicolor LED indicates the output contact status of internal relays K1 and K2. (Emitter-only
models have a Green Power ON/OFF indicator.)

WARNING . . .
This Interface
Box is not a point-of-operation
guarding device, as defined by OSHA
regulations.
It is necessary to install point-of-operation
guarding devices, such as safety light screens
and/or hard guards, to protect personnel from
hazardous machinery. Failure to install point-
of-operation guards on hazardous machinery
could lead to serious injury or death.
