The IA-3178-U2i-P is a 32 Channels Industrial Relay Controller, with 32 Power Relays and an Isolated, High Voltage Line Monitor, designed and produced by Intelligent-Appliance. Each relay has a Contact Rating of 16Amp @ 30VDC, and 16Amp @ 240VAC. Each relay is of SPDT kind, one Change-Over, while it may be used as a DPDT, two Change-Over, set by software and internal logic. The IA-3178-U2i includes an Isolated USB port and two Watchdog circuits. The USB port isolation avoids PC Ground Loops and EMI/RFI Interference, while the second Watchdog helps better handling Host PC and Communication failures.

The IA-3178-U2i can be controlled by a USB port or by an RS-232 port, while it can be easily and transparently chained by other Intelligent-Appliance Series-3000 products. The IA-3178-U2i is CE and FCC Approved and ROHS compliant.
