12-pin I/O Terminal Connector: The CNVETX1 unit provides one relay contact comprised of the
Common Contact, the Normally Closed Contact, and the Normally Open Contact. The current
through the contacts should not exceed 1 Amp @ 30 VDC load. The CNVETX1 also provides two
TTL alarm inputs. The alarm inputs are designed as a digital logic input (-0.3V to 0.6V logic 0, 1.2V
to 5V logic 1), and are pulled up by default. One RS232 port and one RS422/485 port are also
provided.
Pin-out information for the 12-pin terminal block is provided below:
