Power supply

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
