J553 PCRELAY8/IN8
Introduction
The PCRELAY8/IN8 is an 8-bit ISA bus add-on board providing 8 changeover relays. 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’.

Installation for CE Compliance
To maintain compliance with the requirements of the EMC directive (89/336/EEC), this product must
be correctly installed. 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.
