 | PEX-251100
4-Channel Transfer Contacts Mechanical Relay and Individual-Isolated +12 Vdc to +24 Vdc Digital Input/Output PCI Express Product
The PEX-251100, a digital input and relay output product for PCI Express-based computers, provides four photo-isolated input channels (AC input type) and four contact high-current drive relay output channels (form C relay). Input/output partitions are optically isolated from the PCI Express interface block. Each input channel is isolated by individual isolated ground. This feature allows you to use a different supply voltage. This product can drive up to 2 A per channel in relay output circuits. This product supports external reset signal input. This product includes a timer/counter circuit which can be used as an interval timer.

 | PEX-284122
Isolated 16-Channel Digital Input and 16-Channel Digital Output +5 Vdc to +24 Vdc/60 mA PCI Express Product (On-Board Isolated Power Supply)
The PEX-284122, a digital input/output product for PCI Express-based computers, provides 16 photo-isolated high-voltage input channels (source type) and 16 high-current drive open-collector output channels (sink type). Input/output partitions are optically isolated from the PCI Express interface block. The input/output circuits require no external power supplies because the circuits are powered by on-board isolated power supply. This product provides a wide voltage range. The voltage range of input/output circuits is +5 Vdc to +24 Vdc. The maximum voltage rating is +30 Vdc. Input/output handshaking circuits enable to read latch and support input/output data by synchronizing with an external circuit. An external signal enables output of reset signal and input of external reset signal. This product includes a timer/counter circuit, which can be used as an interval timer.

 | PEX-H285144
Isolated 32-Channel Digital Input and 32-Channel Digital Output +12 Vdc to +24 Vdc/100 mA PCI Express Product
The PEX-H285144, a photo-isolated digital input/output board for PCI Express-based computers, provides 32 photo-isolated high-voltage input channels (source type) and 32 high-current drive open-collector output channels (sink type). The product includes a timer/counter circuit which can be used as an interval timer. The product incorporates input/output control circuits and data can be transferred between the product and external devices with handshake. The external signal (STB1) can latch all input data simultaneously. The latch in the input circuit is software selectable from address latch and normal input (through input). The product supports reset signal output and external reset signal input.
