PM1205

The PM1205 is a AC Solid State Switch using optical coupling with dual power SCR outputs to produce an alternative to optocoupler and Triac circuits. The PM1205 switches are robust enough to provide a blocking voltage of up to 500V. In addition, tightly controlled zero cross circuitry ensures switching of AC loads without the generation of transients. The input and output circuits are optically coupled to provide 3750V of isolation and noise immunity between control and load circuits. As a result the PM1205 is well suited for industrial environments where electromagnetic interference could disrupt the operation of electromechanical relays.

Features of the PM1205 are:(1)load current up to 0.5A; (2)500V Blocking voltage ; (3)5mA sensitivity; (4)zero-crossing detection; (5)DC control, AC output; (6)optically isolated ; (7)TTL and CMOS Compatible; (8)low EMI and RFI generation; (9)high noise immunity; (10)VDE compatible; (11)machine insertable, wave solderable.

The absolute maximum ratings of the PM1205 can be summarized as:(1)reverse input voltage:5 V;(2)storage temperature range:-40 to 125;(3)input control current:50mA;(4)input power dissipation:150mW.Absolute Maximum Ratings are stress ratings. Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this data sheet is not implied. Exposure of the device to the absolute maximum ratings for an extended period may degrade the device and effect its reliability.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
