AC Interface Box
Input Voltage and Current 100-230V ac ±15%
Input current: typ. 0.37A @ 100V ac in
typ. 0.23A @ 200V ac in
Inrush current: typ. 15A @ 100V ac in (5 ms max.)
typ. 30A @ 200V ac in (5 ms max.)
Output Voltage and
Current 24V dc @ 0.7 A (16.8 W)
SELV; capable of buffering 20 ms power interruptions
Input Channels 24V dc ± 15%; 40 mA per channel (pin 4 and pin 5 in Figure 3)
Supply Protection
Circuitry Protected against transient voltages
Output Configuration Models EZAC-R.. only; see models listing on page 1
Each normally open output channel is a series connection of contacts from two forced-guided (positive-guided) relays, K1-
K2. The normally closed contact is a parallel connection of contacts from K1-K2.
Contacts: AgNi, 5 µm gold-plated
Low Current Rating:
Caution: The 5 µm gold-plated contacts allow the switching of low current/low voltage. In these low-power
applications, multiple contacts can also be switched in series (e.g., “dry switching”)
To preserve the gold plating on the contacts, the following max. values should not be exceeded at any time:
Min. voltage: 1V ac/dc Max. voltage: 60V ac/dc
Min. current: 5 mA ac/dc Max. current: 300 mA
Min. power: 5 mW (5 mVA) Max. power: 7 W (7 VA)
High Current Rating:
If higher loads must be switched through one or more of the contacts, the minimum and maximum values of the contact(s)
changes to:
Min. voltage: 15V ac/dc Max. voltage: 250V ac/dc
Min. current: 250 mA ac/dc Max. current: 8 A
Min. power: 5 W (5 VA) Max. power: 200 W (2000 VA)
Mechanical life: 50,000,000 operations
Electrical life: 100,000 operations (typical @ 200 W [2000 VA] switched power, resistive load)
Feedback Contact Rating (Y1-Y, Y3-Y):
Min. voltage: 1V ac/dc Max. voltage: 60V ac/dc
Min. current: 5 mA ac/dc Max. current: 300 mA
Min. power: 5 mW (5 mVA) Max. power: 7 W (7 VA)
NOTE: Transient suppression is recommended when switching inductive loads. Install suppressors across load.
Never install suppressors across output contacts (see Warning, page 9).
Output Response Time 10 ms (max.)
Status Indicators Models EZAC-R.. : One bicolor (Red/Green) LED indicator on box cover indicates the power and output status of internal
relays K1 and K2; see page 2.
Models EZAC-E.. : One Green LED indicator on box cover indicates the power status (ON when power is ON).
