Module 6870 is a GPS clock in a compact aluminium housing for 35mm DIN rail mounting (DIN EN 60715 TH35). The module is easily clipped onto the rail via a clip based on "snap-in" mechanism.

Module 6870 has two (2) individual and independent interfaces and is available in six (6) different interface versions. The interface COM0 is always implemented as RS232. The design of interface COM1 depends on the interface version of Module 6870.

The different interface versions of Module 6870 provide the below parameterizable signal outputs via the hmc (hopf Management Console):

Interface Version 1 (RS232/RS422)
Serial interface COM0: RS232
Output of serial string / connection to hmc (hopf Management Console)
Serial interface COM1: RS422
Output of serial string (independent of COM0)
3x optical coupler pulse outputs (potential free)
Output of cyclic pulses, DCF77 pulse (1Hz) or status messages
1x analogue output via BNC
Output of DCF77 antenna simulation (77.5kHz)
Interface Version 2 (RS232/RS232)
Serial interface COM0: RS232
Output of serial string / connection to hmc (hopf Management Console)
