PCLT-2A
Dual current limited over-voltage protected digital termination
Applications
■ Type 1, 2 and 3 logic input termination for
www.DataSheet4U.comindustrial automation
■ AS-Interface bus input termination
■ I/O termination in programmable logic
controller
■ Proximity detector interface
■ Decentralized Input / Output modules
Features
■ 2 channel topology
– Low side input with common ground
■ Wide range input DC Voltage:
– VI = - 0.3 to 30 V with RI = 0 Ω
– VI = - 30 to 35 V with RI = 750 Ω
■ Current limiter:
– 3 to 7.5 mA programmable reference
– ILIM = 6.1 mA to 8.8 mA with RREF = 10 kΩ
– ILIM = 2.8 mA to 4.3 mA with RREF = 22 kΩ
– Narrow limiter spread: < 17 %
– Temperature compensated operation
■ Output drive:
– No output activation below 2 mA input
current
– 1.5 mA minimum output activating current
in opto-coupler mode
– Programmable CMOS output mode option
(VMOD > 2.9 V)
■ LED drive for sensor status: 4.4 mA typical with
RREF = 10 kΩ
■ Input protection (RI = 750 Ω CIN = 22 nF)
■ IEC61000-4-2 electrostatic discharge ESD,
Level 4
– In contact, ± 8 kV; in air, ± 15 kV
– Criteria B: temporary disruption

TSSOP14
Exposed pad
■ IEC61000-4-5 voltage surge, Level 3
– ± 500 V with 42 Ω series resistor in
differential mode
– Criteria B: temporary disruption
■ IEC61000-4-4 transient burst immunity
– ± 4 kV peak voltage; 5 kHz repetitive rate
– Criteria A: fully functional
■ IEC61000-4-6 conducted Radio Frequency
Interference immunity
– 10 VRMS voltage
– Criteria A: fully functional
■ Input protection against -30 V reverse polarity
■ Ambient temperature: -25 to 85 °C
Benefits
■ Enable input to meet type1, 2 and 3
characteristics of IEC61131-2 standard
■ Compatible operation with 2 & 3 wires
proximity sensor according EN60947-5-2
standard
■ Flexible configuration driving either opto
coupler, or CMOS bus controller input, or 12 V
AS-interface network
■ Reduced overall dissipation
■ Enhanced functional reliability
■ Compact with high integration
■ Surface Mount Package for highly automated
assembly
■ Insensitive to the on state sensor impedance
