Overview
The Modicon AS-B804-016 is a 115VAC discrete output module designed for integration with Modicon PLC systems. This module consists of sixteen independent outputs divided into two groups of eight. The B804-115 Vac (16 point) Output Module converts logic signals used in the PLC into 16 independent 115 Vac outputs, with each output capable of driving a relay, pilot lamp, motor starter, solenoid, or any other load up to 2.0 A.
Key Features
- 16 discrete output points, arranged in two groups of eight per common for structured signal control
- Capable of handling a total continuous current of 6 A/group of eight points and 12 A/module
- Uses triac switches to control loads connected to an external power source; switches are designed to withstand high surge currents typical of industrial loads
- Compact form factor for space-efficient panel installation
- Optical isolation from controller for noise immunity and safety
