Hi Mark, 

yes, all the Barionet "extension" units can be also used standalone and 
have an RS-485 port which talks standard Modbus/RTU.
Any product/software which can talk Modbus/RTU should be able to work with 
these devices (including ECS of course).


IO12: US retail price is $195 (the IO12 is 12 inputs AND 12 current 
sourcing industrial grade DV outputs, each can soucrce 
1Amp at 24V, there is a limitation on the total current). 

R6: US retail price is $139, this is a "relay" unit providing 6 relays 
with switchover contacts (product is UL listed UL and can be used 
to switch AC line voltage, 10Amps per relay).

X8: US retail price only $70, this is the "cheap" wiegand reader/temp 
sensor/contact closure/analog input/digital output unit.
It provides 8 versatile inputs/outputs which can do all kind of things, 
including talking onewire to a connected DS18(B)20 temp sensor,
measuring analog voltages (0..5V), sensing contact closures, or even 
interfacing to a Wiegand reader.

Greetings !

Johannes





Hi Johannes,
can the IO12 act alone (i.e without the barionet) ?
what is it's retail price ?
btw, the IO12 data sheet notes 12 digital-inputs, but no inputs are 
mentioned on your web page.
thanks,
