The Allen-Bradley 1336F-LA3 Analog Interface Option Board with dual isolated outputs is an optional analog interface card for the 1336 Plus II drives. This analog interface board is designed to work with all frame sizes that are available for the 1336 Plus II drives. The 1336 Plus II adjustable frequency drives series is a series of general-purpose drives that are designed to provide reliable speed and torque control. These drives produce Pulse Width Modulation (PWM) adjustable output frequency and voltage output for exceptional motor speed and torque control. The 1336 Plus II drives’ output can be adjusted to get the desired performance under a wide variety of loads. These drives support output power ratings from 0.37 kilowatts to 448 kilowatts (0.5 Horsepower to 600 Horsepower). The supported mounting options include the NEMA Open Type, NEMA Type 1, and NEMA Type 12 enclosures.

The Allen-Bradley 1336F-LA3 Analog Interface Option Board replaces the standard Analog Input 2 with 2 galvanic isolated analog outputs (Analog Output 0 and Analog Output 1). Both analog output channels are configured for 0 to 10 Volts DC or 20 milliamps of power. The 1336F-LA3 Analog Interface Option Board is wired to  Terminal Block 2 (TB2) with jumper connectors J10 and J9 in the host drive. Both the J10 and J9 connectors have 4 connector pins each that must be in place with the terminal block before the 1336F-LA3 Analog Interface Option Board’s outputs are activated. Like most 1336 analog interface boards, the 1336F-LA3 Analog Interface Option Board is configured with DIP switches. It has 2 DIP switches (SW51 and SW1) on its surface for configuring the off or on state and for choosing voltage or current operation.
