It is recommended that a mini- EV f mum of 5 VDC open circuit voltage with RS = I f an appropriate series resistance be used to drive LED devices. This minimizes cur- rent variation and its effect on temper- ature and forward voltage of the LED. WHERE: RS = Series Resistance Maximum drive current is 30 mA. Reverse E = Supply Voltage voltage breakdown of the LEDs is 4 volts V = Forward Voltage f (min.). of LED I = Circuit Current f MML92 ORDER GUIDE LEDs should be the same color as the lenses they illuminate. They are packed 10 per listing, including stand-off spacers for use when solder terminating to a printed wiring board, per procedure 3 on page 86.

LED INSTALLATION 1. With Printed Wiring Board Receptacle. (MML93K) 3 PWB receptacle enables T-1 4 or T-1 LEDs to be added or replaced from behind the printed wiring board, with- out soldering. LEDs and receptacles are ordered separately. See page 87. Printed wiring boards are not supplied. 1 1. Insert the LED/PWB receptacle as- 2.

With Solder Terminal Receptacle. (MML93J) This receptacle attaches directly to the rear of panel-mounted units. It enables incandescent lamps to be added or replaced without rewiring. LEDs and receptacles are ordered separately. This receptacle is for use with all rect- angular pushbuttons and MML41 or MML46 rectangular indicators only. 1 2. A 8turn clockwise applied to the re- 1.

By Soldering to Printed Wiring Board or Leadwire (MML44 indicators only). 3 T-1 4 LEDs are added to MML44 in- dicators via a procedure which is unique to this product. The LED is in- serted from the top of the housing with the leadwires protruding through the housing base. 1. Assemble LED to MML44 indicator, 2. Use pencil eraser to snap LED securely with the LED terminals protruding in place. through assembly slot in the middle of housing base. 86 Honeywell1 Sensing and Control1 1-800-537-6945 USA1 F1-815-235-6847 International 1 1-800-737-3360 Canada
