Real Time Clock
Real Time Clock

The EP070 is a microprocessor controlled module that features a fully functional Real Time Clock designed to output the time and date in ISO 8601 format. It employs an internal certified battery backup to maintain time and date during power cycles.

The EP070 features an internal network communications controller using EtherNet/IPTM protocol to set and retrieve the time and date data.

The data available includes Year, Month, Day, Hours, Minutes, Seconds, and milliseconds. The EtherNet/IPTM port allows simple setup of IP address and communication with other industrial devices on the local network such as PLC and HMI units.

  • Approved for explosive atmospheres Zone 0 Group I and Group IIC T4
  • EtherNet/IP communication Interface with a standard RJ45 socket
  • Battery Back-up Power for continuous time stamps
  • Millisecond precision timestamp output in ISO 8601 Time Format
  • EtherNet/IP LED status indication


Network communication for the EP070 unit is facilitated through the use of a standard RJ45 socket supporting the EtherNet/IPTM protocol. Physical layer support is via standard Auto-Sensing 10 Base-T / 100Base-TX Ethernet and includes Ethernet Activity and EtherNet/IPTM status LED indicators.

The EtherNet/IPTM (EIP) interface consists of an input assembly object and an output assembly object. The module will use a BOOTP server if it is available.

If the BOOTP request fails, the EP070 will revert to using the IP address in non-volatile memory, this will be the previously assigned IP Address. The time out occurs after approximately 30 seconds.
