Terminal 27-28; 24V DC Power Supply:
Use these terminals ONLY for DC operated applications. The supply must be a 24V DC +10%.
For AC applications, use terminals 22-24.
Terminal 35 to 37: Type CB / CH - RS232/485 (2-wire) communication (optional) :
▪
Full serial communications and computer control in accordance with RS232 (length of cable max. 15
meters) or RS485 (length of cable max. 1200 meters) is possible.
▪
Read the Modbus communication protocol and Appendix C.
Terminal 42 to 45; control output R1:
This mechanical relay output is available to control the batch process. Relay 1 is switched-on during the
whole batch process. Max. Switching capacity (resistive load): 8A @ 250V AC / 30V DC.
Max. Switching power (resistive load): 2000VA 240W.
Figure 25: Terminal connections - Mechanical relay output (typical)
Terminal 46 to 48; control output R2:
The function of the mechanical relay 2 is determined by SETUP function 7.1.
Max. Switching capacity (resistive load): 8A @ 250V AC / 30V DC.
Max. Switching power (resistive load): 2000VA 240W.
Note: The schematic diagram shows some typical applications to control a pump, a valve or an alarm.
