Introduction
IO Connection Box is an accessory for the FR22, FR22 Lite and Sampo S3 products. It extends the IO features of the main device by offering opto-isolated inputs and outputs. In addition to the IO’s, the IO connection Box has two relays to interface with devices requiring high wattage or an open/short signal. The IO Connection Box offers a robust and flexible connection of external devices (e.g. lights, buzzers) and triggering sources (e.g. sensors, buttons). It is connected to the Industrial Mini IO port of the RFID reader via a provided cable, providing easy access to the pins of the IO port with pluggable screw terminals. The IO’s and the relays are controlled via the main device’s APIs (either via NurAPI or device’s system RPC API).
