4.2.9 Motorized Valve – Fig. 4.6
A motorized valve with or without feedback requires 2 relays (common and normally open terminals) to drive the valve in either
direction. Any two relays can be allocated for this function. Fig. 4.6 A shows two possible combinations.

Notes.
1 Type 1 and type 2 modules have one relay output, therefore two modules are required.
2 Link must be connected at valve drive end, not at the controller terminals.
