A1-A: 115V ac (Model ES-UA-5A) or 230V ac (model ES-VA-5A), ± 15%; 50/60Hz
B1-B: 12-24V dc, ± 15%, 10% max. ripple
Power consumption: approx. 4W/7VA
Protected against transient voltages and reverse polarity
Outputs (K1 & K2): four redundant (total of eight) safety relay (forced-guided) contacts – AgNi, 5 µm gold-plated,
plus 1 N/C Auxiliary Monitor output – 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-
To preserve the gold plating on the contacts, the following max. values should not be exceeded at any time:
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:
Mechanical life: 50,000,000 operations
Electrical life: 150,000 operations (typical, @ 1,500 VA switched power, resistive load)
NOTE: Transient suppression is recommended when switching inductive loads. Install suppressors
Solid-State Monitor Outputs:
Two non-safety solid-state dc outputs
Output at Y32 monitors state of outputs – conducts (output high) when both K1 and K2 are energized
Output at Y35 conducts (output high) when internal power supply is OK
Output circuits require application of +12-24V dc ± 15% at terminal Y31; dc common at Y30
Maximum switching current: 100 mA at 12-24V dc
Both outputs are protected against short circuits
25 milliseconds typical
E-stop switch must have normally closed contacts each capable of switching 20 to 50mA @ 12 to 30V dc;
and must be open ≥ 10 ms for a valid stop command. Maximum input resistance 250 Ω per channel.
Reset switch must have one normally open contact capable of switching 20 to 50mA @ 12 to 30V dc.
100 ms; time from the E-stop contacts to close (Auto Reset) or the reset button to open (Manual Reset) and the
safety outputs to close.
 green LED indicators: Power ON, K1 energized, K2 energized
1 red LED indicator responds to fault of internal power supply, ground fault, or cross-short of input channels (see
“Troubleshooting” on back cover for LED condition descriptions).
Polycarbonate. Rated NEMA 1 (IEC IP20)
Mounts to standard 35 mm DIN rail track. Safety Module must be installed inside an enclosure rated NEMA 3
(IEC IP54), or better.
10 to 55Hz @ 0.35 mm displacement per IEC 68-2-6
Operating Temperature: 0° to +50° C (+32° to 122° F)
