The ES-194U (24 hour) is a low-cost Master Clock for applications not requiring GPS or temperature controlled stability. Like the LX-192U/194U, the ES-192U/194U uses the AC line-frequency as a time reference or, optionally, a quartz crystal timebase may be specified. Time & Date data are output to Slave displays via the TC90 Time Code output. HR Relay Contact Closure: A contact closure occurs at the top of each Hour. Relay contacts are rated at 10-Watts maximum load, 500mA maximum switching current.
BBU - Battery Back-Up: An internal Gel-Cell battery is provided capable of maintaining the unit's microprocessor for up to a 4-hour power outage. Option P must also be specified when ordering this option.
C - Crystal Time Base: A crystal reference is employed for those applications requiring independence from the line frequency. A trimming function is included for greater accuracy (2-3 seconds/week).
Clear Clear Anodized Front Panel
D - Remote Control: This option consists of a connector wired to switches on a control plate via a six-foot cable. Extra cable available.
J - 220 VAC/50 Hz Operation: The unit is configured to operate from 220 VAC line voltage. 117 VAC 50/60 Hz is standard.
P - 19" Front Panel (Rack Mount): Designed for mounting into a standard equipment rack. Panel is 1/8" clear or black anodized Aluminum and chassis is 5" - 10" deep.
P2 - Dual Rack Mount: Allows specific units to be mounted side-by-side on a single Rack Mount panel.
Q - Console Mount: The unit is housed in an enclosure 8" deep, front panel is 3.5" x 9", 1/8" clear anodized aluminum.
RS - RS-232C Output: Computer Interface allows the time code data to be shared with a computer. RS-422A may be specified.
UL - "UL" Approved Power Supply: The unit is supplied with a UL/CSA approved wall mount power supply.
