ROSSLARE MD-IO84 IO Expansion Card

The MD-I084 is an optional expansion card for Rosslare's family of state-of-the-art network access controllers, especially the AC-225 and AC-425 models.

The expansion card adds four additional relay outputs and eight monitored inputs to the access control center.

The host access controller can fully control the additional inputs and outputs of the MD-IO84 expansion card. Inputs and outputs can be configured using the Rosslare access control software system. The software system also configures the input connection topology of the MD-IO84.

- 8 supervised, 4-state, dual EOL input relays
- 4 fully programmable 5 A Form-C relay outputs
- 4 indicator LEDs
- Optional extension for AC-225, AC-425
