Features:
- Two safe 0(4)-20 mA output channels
- Active and passive loop operation
- Independent D/A output and A/D readback
FS-SAO-0220m sends two supervised analog commands to compatible final elements.
Active and passive modes require different loop-power and voltage-drop calculations.
Testing must compare commanded current, measured current, readback value and final-element response.
The Honeywell FS-SAO-0220m 2-Channel Safe Analog Output Module is available for quotation and technical support from Apter Power.
