C4-5 AI4 Analogue input # 4 (NTC probe, 0-20 or 4-20 mA transducer)
C4-6 AI3 Analogue input # 3 (NTC probe, 0-20 or 4-20 mA transducer)
C4-7 AI2 Analogue input # 2 (NTC probe)
C4-8 AI1 Analogue input # 1 (NTC probe)
C4-9 12 V AC (power
supply) Instrument power supply (12 V AC/DC)
C4-10 12 V DC Power supply for current transducers and EVCO’s EVDFAN1 phase-cut
module (12 V DC)
C4-11 AO1 Output for EVCO’s EVDFAN1 phase-cut module
C4-12 DI5 Digital input # 5
C4-13 DI4 Digital input # 4
C4-14 DI3 Digital input # 3
C4-15 DI2 Digital input # 2
C4-16 DI1 Digital input # 1
To enable the use of the EVDFAN1 phase-cut module, the controller must be powered by an alternating
current supply; the controller’s powering phase must be the same one that supplies the module.
Connector 5 : Connector for EVCO remote keyboard / expansion
Conn. Label Description
C5-1 12 V DC Power supply for remote keyboard (12 V DC, 50 mA max.)
C5-2 GND Common
C5-3 SERIAL EVCO live serial port
The power supplies of the controller and the expansion must be galvanically isolated from each other.
