The Matrix Alarm Interface is a scalable distributed digital input/output unit. Alarm input/output ports, each with a specific
functions, control the alarm processes. The basic input/output element (MXALM) has a maximum capacity of 512 digital inputs
or 512 digital outputs. Capacity can be expanded up to 1 024 inputs/outputs by combining two units.
The MXALM is composed of the following individual functional modules:
• Card cage
WJ-SX850
• 32ch Alarm Input Board
WJ-PB85A32
• 32ch Alarm Output Board
WJ-PB85L32
