The power switching rating is 60W (resistive load). This allows supplies upto 48v DC and switching currents 1.0A. There are also 8 opto-isolated inputs providing an input to output isolation of 1500v. Features CE compliant design 8 changeover relays with a power switching rating of 60W (resistive load) Switching voltage up to 48v DC and switching currents up to 1.0A 8 opto-isolated inputs complete with two current limiting resistors per input Opto-input switching voltage: 10v to 30v Output status readback register Occupies 4 Bytes of Address Space Relay drivers disabled on power-up and reset Both normally closed and normally open relay terminals are available at the I/O connector Link selectable debounce option on inputs Link selectable, even boundary base address Board access LED Operating temperature range, +5°C to 55°C Power consumption +5V ±0.25V 250mA typical + 40mA per relay operating Relay life rating 500,000 operations minimum (DC full load) Getting Started Switch off PC Install board in supplied configuration Switch on PC Run EXAMP-01.EXE (supplied on the utility disk) An access/user LED should flash. If not check default link configuration (Page 5) Operation Each relay is switched by writing a 1 to the relay output register. On power-up or reset the output latches that drive the relay drivers are disabled. To enable them it is necessary to write 01 to base address +1. For system initialisation, it is recommended that the output register is written with the required relay states before the relay relay enable bit is set. The status of the opto inputs is read form I/O address base +1. When an input channel is switched on the value read by the host will be a 0.

The PC in which the board is housed must be CE compliant as declared by the PC manufacturer. The type of external I/O cable can be chosen according to the notes below: 1. Remove the cover of the PC observing any additional instructions of the PC manufacturer. 2. Locate the board in a spare ISA slot and press gently but firmly into place. 3. Ensure that the metal bracket attached to the board is fully seated. 4. Fit the bracket clamping screw and firmly tighten this on the bracket. Note: Good contact of the bracket to the chassis is essential. 5. Replace the cover of the PC observing any additional instructions of the PC manufacturer. Cable Cable length 1 Metre or less Cable 1M to 3M : : Longer cable or noisy environment : Ribbon cable satisfactory Commercial screened cable gives the protection required Use fully screened cable with metal backshells e.g. Arcom CAB50CE The following standards have been applied to this product: BS EN50081-1: 1992 Generic Emissions Standard, Residential, Commercial, Light Industry BS EN50082-1: 1992 Generic Immunity Standard, Residential, Commercial, Light Industry BSEN55022: 1995 ITE Emissions, Class B, Limits and Methods Page 5 2192-09458-000-000 Page 6 J553 PCRELAY8/IN8 J553 PCRELAY8/IN8 2192-09458-000-000 Page 7 2192-09458-000-000 J553 PCRELAY8/IN8 Revision History Manual Issue A Issue B Issue C Issue D Issue E Issue F Issue G Page 8 PCB V1 I1 V1 I2 V1 I3 V1 I3 V1 I3 V1 I3 V1 I3 Comments 960927 961129 970124 970207 970326 980127 980707 First full release of Manual.
