104-DIO8 PC/104 eight isolated and TTL in- puts, eight electro-mechanical relay outputs digital card Rugged embedded monitoring and control The 104-DIO8 is a PC/104 solution for digital header cable such as the CAB50A-3 or Eight electro-mechanical relay outputs control where on board relays are required CAB50A-6 can be used with either the UTB or and inputs must be isolated such as in test STB50 50-pin screw termination boards. Eight optically isolated AC or DC inputs equipment, instrumentation and process control. The electro-mechanical relays are The 104-DIO8 is one of the few onboard relay Eight TTL digital inputs preferred in applications where no leakage is and isolated input PC/104 boards that has the 50-pin IDC ribbon cable connection allowed and larger current is required than can change-of-state interrupt feature that allows Standard PC/104 compatibility be provided by reed relays. Standard default the PC/104 CPU to be notified when data has Change-of-state interrupt on input range is 3 to 28VDC or AC and output changed on the input ports which greatly frees isolated inputs relays can carry 1A @ 24VDC. The 104-DIO8 up system resources by eliminating the need ® ® DOS, Linux , Windows 98/2000/NT additionally has available eight TTL inputs for for constant polling of inputs. This can be full I/O support reading dry contact closures or any TTL critical in embedded applications where lower compatible outputs from another device. The speed processors are used to reach higher 104-DIO8, unlike our ISA DIO8-P and PCI- temperatures or to maintain lower power use. DIO8, offers eight Form C relays in addition to the eight additional TTL inputs because its I/O The isolated inputs can be driven by either AC interfaces through a 50-pin IDC connector or DC and are not polarity sensitive. Input instead of a DB37. A standard 50-pin ribbon signals are rectified by a diode bridge and connected across an LED diode of an opto- response to zero crossings. The filter is also isolator. A 1.8k ohm 0.5W resistor in series valuable for use with slow DC input signals in a provides current limiting. Standard 12/24AC noisy environment. The filter may be switched control transmitter outputs can be accepted out for DC inputs in order to obtain faster as well as DC voltages. Although the standard response. Filters are individually switched on input voltage range is 3 to 28V (rms), the input or off by jumpers. voltage range can be extended by connecting external resistors in series. Each input circuit The electro-mechanical relay outputs are contains a software switchable slow/fast filter comprised of one group of eight Form C SPDT that has a 5ms time constant. The filter must outputs. The relays are all de-energized at be selected for AC inputs in order to eliminate power-on. Data to the relays is latched. 104-DIO8 - Technical Specifications Bus Power Requirement • PC/104 • +5VAC @ 400mA (all relays ON) Channels • Eight isolated inputs Environmental • Eight TTL inputs Operating Temperature • Eight relay outputs • -30 ° to 70 °C (-22 ° to 158 °F) Humidity Isolated Inputs • 0 to 90% RHNC (max.)
