E-Stop and Guard Monitoring Modules

ES-TN-14H.. Safety Module Specifications

Supply Voltage and Current 24V dc, ±20% Power consumption: approx. 5 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, gold flashed one auxiliary normally closed contact – AgNi, gold flashed Outputs K3 & K4: four redundant (total of eight) delayed relay (forced-guided) contacts – AgNi, gold flashed one auxiliary normally closed contact – AgNi, gold flashed Max. voltage: 250V ac or dc Contact ratings (all normally open and normally closed output contacts): Max. current: 4 A ac or dc Min. current: 30 mA @ 24V dc Max. power: 1000 VA, 100 W Mechanical life: 50,000,000 operations Electrical life: 100,000 at full resistive load NOTE: Transient suppression is recommended when switching inductive loads. Install suppressors across load. Never install suppressors across output contacts.Output Response TimeK1 & K2: 50 milliseconds typical K3 & K4 (ES-TN-14H5): 0, 0.5, 1, 2, 4, 6, 8, 10, 15, 20 seconds K3 & K4 (ES-TN-14H6): 0, 5, 10, 20, 30, 50, 70, 100, 150, 200 seconds Delayed Output Timing Tolerance: Set time ±100 milliseconds or ±2%, whichever is greater Input RequirementsInput switch must have a normally closed contact capable of switching 20 mA @ 24V dc. Reset switch must have one normally open contact capable of switching 20 mA @ 24V dc.NOTE: Inputs must be voltage-free, dry contacts.
SAFETY MODULES ON-Time Delay ≥ 100 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
