In the automation of laboratory instruments, there is a need to include time checks in process monitoring reports. A time of day feature conveniently can be added to commercially available processorcontrolled device couplers without internal modification of the coupler. All additional circuit components to provide the time of day feature can be wired onto a card which is pluggable into the device coupler motherboard. Cabling to the digital input module and digital output module of the device coupler and to the secondary winding of the 60-cycle power transformer of the device coupler completes the installation. The clock is then set and read via the controlling processor software.
