ES-..A-5A Safety Module 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 Circuitry Protected 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 1 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, the following max. values should not be exceeded 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: 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, @ 1,500 VA switched power, resistive load) 150,000 operations (typical, @ 200 W switched power, resistive load)
SAFETY MODULES Output Response Time Note: Transient suppression is recommended when switching inductive loads. Install suppressors across load. Never install suppressors across output contacts.Solid-State Monitor Outputs: 25 milliseconds typical
PICO-GUARDCONTROLLERS Input RequirementsInput switch must have normally closed contacts each capable of switching 20 to 50 mA @ 12 to 30V dc; and must be open ≥ 10 milliseconds for a valid stop command.
E-STOP/GUARDMONITORING - 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 Reset switch must have one normally open contact capable of switching 20 to 50 mA @ 12 to 30V ac/dc. ON-Time Delay 80 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.
SAFETY MATMONITORING MUTINGMODULES Status Indicators3 green Led indicators: 1 Red LED indicator: Construction Polycarbonate housing Power ON Fault (internal power supply, ground fault, K1 energized short across the input channels or other K2 energized internal failures) Environmental Rating Rated NEMA 1; IEC IP20
EXTENSIONMODULES Mounting Mounts to standard 35 mm DIN rail track. Safety Module must be installed inside an enclosure rated NEMA 3 (IEC IP54), or better.
INTERFACEMODULES Vibration Resistance 10 to 55Hz @ 0.35 mm displacement per IEC 68-2-6 Operating ConditionsTemperature: 0° to +50° C Relative humidity: 90% @ +50° C (non-condensing) Certifications For a list of certifications see page 237.
