Modicon B350

The Gould B350-001, 115 VAC Output Module converts logic signals used within the Micro 84" Programmable Controller into 8 independent 115 VAC outputs. Each output is capable of driving relays, pilot lamps, motor starters, solenoids, or other loads up to 2.0 amperes. The module uses 8 triac switches to control loads connected to an external power source. These switches are designed to withstand the high surge currents typical of industrial loads.

Each output is electrically isolated from the controller by an optical coupler. This enables the module and controller to withstand the severe voltage transients prevalent in an industrial environment. The module employs a zero-cross switching technique. This feature minimizes switching noise, extends the life of the triacs, and improves system reliability. Both IEEE and ANSI standards for surge withstand capability (SWC) tests are fully satisfied.

The output circuits are divided into two groups of four outputs each. Each group is driven by a separate voltage source. A neon lamp connected to each circuit's field side displays the ON/OFF status of the output. This lamp indicates the output's true state.
