Introduction
The Protege DIN Rail 16 Input Opto-Isolated Expander extends the number of inputs on the system by 16, allowing
monitoring of a wide range of open contact sensors for security, elevator control and building automation
purposes.
Flexible module network architecture allows large numbers of modules to be connected to the RS-485 module
network. Up to 250 modules can be connected to the Protege system in any combination to the network, over a
distance of up to 900M (3000ft). Further span can be achieved with the use of a network repeater module.
The current features of the isolated input expander include:
⦁
Secure encrypted RS-485 module communications
⦁
16 opto-isolated inputs
⦁
Industry standard DIN rail mounting
⦁
Online and remote upgradeable firmware
