48-ch Digital I/O Isolated USB or RS-232 Controlled IA Series-3000 Daisy-Chain Ik Features Introduction The IA-3124-U2i is a 48-ch Digital I/O Industrial Controller with a Sink Current of up to 1Amp on each output channel and an input voltage range of up to 30VDC. This Power Digital I/O Controller is an ideal Solenoid/Valve/LED controller with the fastest response time and endless operation cycles while comparing to original relay kind solution. The IA-3124-U2i includes an Isolated USB Port that isolates the Host Computer from the IA-3124-U2i I/O lines and from its power supply. In this way the Host Computer is actually isolated from the Factory Floor, the Building wiring net etc., while the IA-3000 Series product may be transparently chained, sharing the same Power-Supply, providing latency free efficient Monitor and Control System. 48-ch Power Digital I/O Controller, USB Cable included. 48-ch Digital I/O 24-ch Solid-State Relays Functions as Power Digital Outputs With Output Current rating of 1Amp 24-ch Digital Inputs 3.3V to 30V Input Range Supports wet and "Dry-Contact" Isolated USB Port for Host Isolation Dual Watchdog Protection Inductive Load Protection on each output Din-Rail Mounting Ready Specifications Digital Output Channels Maximum Current Voltage Range Output Circuit Digital Inputs Channels Voltage Range Logic '0' Logic '1' Communication Main COM Port Secondary Port COM Rate Default BR COM Setup Expansion Port Host Wiring Expansion Wiring General Power Supply Power Consumption Load Current Module Size Weight Specifications are subject to change without notice
