20 OPTOISOLATED DIGITAL INPUTS, 20 RELAY OUTPUTS
The IR104 is a PC104 rugged industrial relay module featuring 20 optoisolated digital inputs and 20 relay outputs, sufficient for many industrial control applications. Each input can accept either AC or DC voltages with a range of 3-24V and are accessed through a 40-pin header that mates with a standard ribbon cable. The 20 SPST (Form A) relays have a long lifetime (20,000,000 operations, 100,000 at full load) and quick actuation time (6ms max operate, 3ms release). The relays are supplied with a contact rating of 250VAC or 30VDC @ 5A giving the IR104 the ability to directly control switches for small motors or solenoids. The relays are in the open state when deactivated / powered off.
To allow for quick and convenient installation, a pair of 20-position detachable terminal blocks accept wire sizes of 14-28AWG. The IR104 is a compact design measuring 3.550" x 3.775" with a maximum component eight of 0.492". A 16-bit PC/104 BUS is included to allow for easy integration into embedded systems or to allow for up to 4 IR104 modules to be stacked together.
The IR104 operates on single 5VDC, has a -25° to +70°C operating temperature range and is now RoHS compliant.
