Universal Input Safety Modules

Overview

  • Monitors a wide variety of safety and non-safety input devices:
    • Optical-based safeguarding devices, such as Safety Laser Scanners
    • Positive-opening safety switches used for guard interlocking
    • Emergency-stop devices, such as palm buttons and rope/cable pulls
    • Standard sensors for non-safety applications, such as photoelectric monitoring position or end-of-travel
  • The safety inputs can monitor:
    • +24V dc solid-state (PNP) outputs in single-channel or dual-channel hookup
    • +24V dc source that is switched by hard/relay contacts in single-channel or dual-channel hookup
    • Hard/relay contacts in a dual-channel hookup using terminals S11-S12 and S21-S22
  • UM-FA-9A: Three normally open (N.O.) output switching channels for connection to control-reliable power interrupt circuits
  • UM-FA-11A: Two normally open (N.O.) and one normally closed (N.C.) output switching channels for connection to control-reliable power interrupt circuits
  • Automatic reset or monitored manual reset, depending on hookup
  • Design complies with Category 4 PLe (ISO 13849-1), SIL 3 (IEC 61508/IEC 62061), and Control Reliable (ANSI B11.19)
  • Safety Integrity Level (SIL) 3 (IEC 61508/62061)
  • Performance level (PL) e (ISO 13849-1)
  • For use in functional stop category 0 applications per ANSI NFPA 79 and IEC/EN 60204-1

Product Specifications

Supply Voltage and Current24V dc ± 10% (SELV-rated supply according to EN IEC 60950, NEC Class 2)

24V ac ± 10%, 50/60Hz (NEC Class 2-rated transformer)

Power consumption: approx. 2W/2VA

Supply Protection CircuitryProtected against transient voltages and reverse polarity
Overvoltage CategoryOutput relay contact voltage 1V to 150V ac/dc:Category III
Output relay contact voltage 151V to 250V ac/dc:Category II (Category III, if appropriate overvoltage reduction is provided, as described in datasheet.)
Pollution Degree2
Output ConfigurationModel UM-FA-9A:3 normally open (N.O.) output channels
Model UM-FA-11A:2 normally open (N.O.) output channels and 1 normally closed (N.C.) auxiliary output channel
Contacts:AgNi, 5 μm gold-plated
Low Current Rating: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, 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:
    Min. voltage:15V ac/dc
    Max. voltage:250V ac/dc
    Min. current:30 mA ac/dc
    Max. current:UM-FA-9A: 6 A; UM-FA-11A: 7 A
    Min. power:0.45 W (0.45 VA)
    Max. power:UM-FA-9A: 200 W (1,500 VA); UM-FA-11A: 200 W (1,750 VA)
Mechanical life:> 20,000,000 operations
Electrical life (switching cycles of the output contacts, resistive load):150,000 cycles @ 1,500 VA; 1,000,000 cycles @ 450 VA; 2,000,000 cycles @ 250 VA; 5,000,000 cycles @ 125 VA
Output Response Time25 milliseconds typical
Input RequirementsSafety Input Switch 2-Channel (contacts) hookup:10 to 20 mA steady state @ 12V dc
    NOTE:Inputs are designed with a brief contact-cleaning current of 100 mA when initially closed.
Solid-State Dual Channel hookup:5 to 20 mA steady state @ 18 to 28V dc sourcing ( PNP), < 2 mA leakage current
Single-Channel hookup:40 to 100 mA @ 24V ac/dc ± 10%; 50/60 Hz
Reset Switch:20 mA @ 12V dc, hard contact only
Minimum OFF-State Recovery Time250 ms (When used with the AG4 Safety Laser Scanner, the “Restart delay time after PF release” must be configured for 280 ms or greater.)
Indicators3 green LED indicators:Power ON, K1 energized, K2 energized
ConstructionPolycarbonate housing. Rated NEMA 1, IEC IP40; Terminals IP20
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 60068-2-6
Operating ConditionsTemperature:0° to +50°C (+32° to 122°F)
Max. Relative Humidity:90% @ +50°C (non-condensing)
Design StandardsCat. 4 PL e per EN ISO 13849-1; SIL 3 per IEC 61508 and IEC 62061
