** Model shown: FDH2A07TR-RN23:
This model requires an external regeneration resistor and customer supplied 24V supply - see sections 3.6 and 3.4.7.
Some models contain an internal 24V supply and/or an internal regeneration resistor.
Demand input may be differential or single ended. See section 4.2.1.
