Design principle
Expansion should not be another project
Plug in and it is recognised
Modules are detected automatically once connected — no station numbers to set and no DIP switches to flick. One fewer error-prone step when adding points on site.
Shared across three gateways
The same modules work with the ETH-A2E, A2L or A2N. Moving from wired to wireless, or running different gateways on different sites, still means one set of I/O spares.
Eight units, 32 points each
Up to eight modules per gateway at 32 points each. When points run short you add a module rather than replacing the controller with a bigger one.
Selection
Choosing among the six
Pick modules by signal type; they can be mixed under one gateway.
Digital signals
TSF-A2-DI16 provides 16 digital inputs and TSF-A2-DO16 provides 16 digital outputs — for switches, limits and status feedback.
Analog signals
TSF-A2-AI6 provides 6 analog inputs and TSF-A2-AO6 provides 6 analog outputs — for pressure, flow and level transmitters and proportional valve control.
Temperature and relay
TSF-A2-RT6 provides 6 temperature inputs and TSF-A2-DO6TR provides 6 relay outputs — for temperature measurement and loads needing a dry contact.
