IO1XXX I/O Expansion Modules

IO1XXX I/O Expansion Modules

Product description

The I/O Expansion Modules are a flexible way to increase the I/O density of the pro-teso range of PLCs. The I/O expansion modules offer a range of alternate types and configurations such as analogue 0-10V, 4-20ma, opticalinputs and relay outputs.

The I/O Expansion Modules connect to the programmable controller via the multidrop RS485 network. Each module has a unique identifier to permit as many as 32 I/O modules to reside on the one RS485 expansion network.
