AK input-output module family
Put line-ups of up to nine self-addressing I/O modules wherever
you need them, and in any combination. Modules are available
with:
• 8 relays (with or without override)
• 8 relays (with or without override) and 8 universal inputs
• 8 universal inputs
• 8 digital inputs (high and low voltage versions)
• 4 bi-polar EEPR outputs
Each module lineup begins with a communications and power
module that is connected to the AK-SC 255 system controller via
Echelon® Lonworks®. No wiring to individual modules is required
because of a unique intermodular bus.
AK-SC 255 Solution components:
• Communication module
• I/O modules
• Pulse counter
Type Function Code no.
