IMS - Modular SynchronizationCOM52HS: DCF77 radio clock for 35mm DIN mounting rail.
Key Features
- Internal DCDC converter for 19..72VDC operating voltage
- Pulses per second and per minute
- RS-232 interface
- Reception status indicated by LED
- DCF77 radio clock
Product Description
RS232 interface via 9 pin SUB-D female connector. Pulse per second and pulse per minute. These pulses are accessable via the ten pole screw terminal.
RS232 Output
An asynchronous serial port can be used to transmit information on date and time to other devices. The clock is configured to send time messages automatically with 9600 baud and with a framing of 7E2 once per second.
Pulse Output
After DCF77 synchronization, a pulse per minute and a pulse per second, with a pulse duration of 0.2 seconds, will be switched on. The generation of the pulses will be maintain for 12 hours if the DCF77 receipt is disturbed. Thereafter the pulses will be deactivated.
Housing
The receiver module is mounted in a plastic housing for 35mm DIN mounting rails. Two status LEDs (for modulation and free-running mode), the BNC antenna connector and a D-SUB9 connector for the serial RS232 interface are integrated in the front side of the housing.
Operating Voltage
The system requires an operating voltage of 19...72V/DC witch is applied via two contacts of the integrated screw terminal. The receiver is DC isolated due to an internal DCDC converter, the isolation voltage is 1,5KV DC.
