Product Specifications

Supply Voltage and CurrentES-UA-5A:115V ac (A1-A2), 12-24V dc, ±15%, 10% max. ripple (B1-B2)
ES-VA-5A:230V ac (A1-A2), 12-24V dc, ±15%, 10% max. ripple (B1-B2)
Power consumption:approx. 7 VA / 4 W
Supply Protection CircuitryProtected against transient voltages and reverse polarity
Output ConfigurationOutputs (K1 & K2):four redundant (total of eight) safety relay (forced-guided) contacts—AgNi, 5 µm gold plated, plus one normally-closed 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. To preserve the gold plating on the contacts, do not exceed the following max. values at any time.
Min. voltage:1V ac/dc
Max. voltage:60V
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 the following.
Min. voltage:15V ac/dc
Max. voltage:250V ac/dc
Min. current:30 mA ac/dc
Max. current:6 A
Min. power:5 W (5 VA)
Max. power:200 W (1,500 VA)
Mechanical life:50,000,000 operations
Electrical life:150,000 operations (typical, @ 200 W (1,500 VA) switched power, resistive load)
Note:Transient suppression is recommended when switching inductive loads. Install suppressors across load. Never install suppressors across output contacts.
Solid-state monitor outputs:Two non-safety outputs 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 circuit:requires application of +12-24V dc ±15% at terminal Y31; dc common at Y30
Max. switching current:100 mA @ 12-24V dc
Output protection:both outputs are protected against short circuits
Output Response Time25 milliseconds typical
Input RequirementInput switch must have normally-closed contacts each capable of switching 20 to 500 mA @ 12 to 30V dc; and must be open 10 milliseconds max. for a valid stop command. Maximum input resistance 250 ohms per channel.



Reset switch must have one normally-open contact capable of switching 20 to 50 mA @ 12 to 30V ac/dc.
ON-Time Delay80 milliseconds; time from the E-stop contacts to close (Auto Reset) or the reset button to open (Manual Reset) and the safety outputs to close.
Status Indicators3 Green LED indicators:
Power:power is supplied to safety module
Channel 1:K1 energized
Channel 2:K2 energized
1 Red LED indicator:fault (internal power supply, ground fault, short across the input channels or other internal failures)
ConstructionPolycarbonate housing
Environmental RatingRated IEC IP20; NEMA 1
MountingMounts to standard 35 mm DIN-rail track. Safety module must be installed inside an enclosure rated NEMA 3 (IEC IP54), or better.
Vibration Resistance10 to 55 Hz @ 0.35 mm displacement per IEC 68-2-6
Operating ConditionsTemperature:0° to +50° C
Relative humidity:90% @ +50° C (non-condensing)
