1.
RS-232 connector:
For the communication purposes, the user connects with the controller via the RS-232 connector (Fig.
7) using the control module
2.
RS-485 / RS-422 connector:
For the communication purposes, the user connects with the controller via the RS-485 or RS-422
connector (Fig. 7) using the control module.
3.
0/20mA digital current loop
For the communication purposes, the user connects with the controller via the digital current loop
connector, (Fig. 7) using the control module.
4.
Operator panel (dry contact)
For the control purposes, the user manipulates the operator panel or relay contacts.
5.
Ethernet
For the communication purposes, the user connects with the controller via Ethernet connector, (Fig.
7) using the control module.
