An external 24 VDC power supply is required. The voltage
range 18 VDC to 28 VDC
A system with 4 analog inputs, 4 analog outputs, 4 digital
inputs and 4 digital outputs requires 0.5 amps.
Eurotherm offers 3 24VDC supplies
2.5 amp (60 watt
5 amp (120 watt)
10 amp (240 watt)
The Eurotherm supply has:
Will hold up power for 20-37 ms. On power fail
