Each input channel may be individually driven by an external source or from the on-board isolated +24V supply. The outputs are configured as open collector drivers with a capability to sink up to 500mA for channels 0 to 5 and up to 300mA for channels 6 and 7. PCIO8 Board inputs driven by external power source PCIO8-DC/DC Board fitted with +24V isolated DC/DC converter to provide excitation supply Features CE compliant design 8 opto-isolated digital inputs 8 opto-isolated digital outputs Output channels 0 to 5 sink up to 500mA 6 and 7 sink up to 300mA Occupies 4 bytes of address space Optional DC-DC converter RC filter providing 10mS of debounce Link selectable base address Board access LED Operating temperature range, +5°C to 55°C Power Consumption PCIO8 150mA PCIO8-DC/DC 500mA MTBF: 559,ooo PCIO8 148,000 PCIO8-DC/DC Getting Started Switch off PC Install board in supplied configuration Switch on PC Run EXAMP-01.EXE (supplied on the utility disk) An access LED should flash. If not check default link configuration. Page 2 J557 PCIO8 2192-09070-000-000 Operation Reading or Writing to the Boards Control of the PCIO8 is achieved by writing to a data register to read or write the required data. Each time the board is accessed the red LED will flash momentarily. Opto-isolated Inputs When an input channel is switched ON the value read by the host will be a 0. Each input is configured as follows: Output Channels Each output channel is switched ON by writing a 0 to the channel control register. The Darlington output will be sinking current when switched ON. On power-up or when reset is asserted, all the outputs are disabled and switched OFF. If the power on the host system is switched off at any time all the outputs will be switched OFF. The outputs are enabled by writing to base +2 address. Page 3 2192-09070-000-000 J557 PCIO8 Power dissipation and current handling for each device IC1 and IC2 In order to prevent damage to the output darlington drivers, the total power dissipation for IC1 (Output groups 0, 1, 2 & 6) and IC2 (Output groups 3, 4, 5 & 7) must be below 760mW @ 25°C. This must be de-rated at 6mW/°C above 25°C. The following chart gives a guideline to maximum current handling for each device, and how this is derated with increased temperature. Note- Output channels 0 to 5 are capable of sinking up to 500mA. Channels 6 and 7 will sink up to 300mA. For further information regarding the output drive capability of this product, please refer to Arcom Product Notice No. 32 which may be found on the Arcom Website, or by using the Arcom Fax on Demand system.
