8 Hardware Installation—IFC-200 Hardware Installation Procedures
The IFC-200 provides four indicating appliance circuits (Style Y only).
Each circuit is capable of producing 2.25 amps of current at 24 VDC.
Total current drawn from these, as well as any other panel DC power
outputs, cannot exceed 5.0 amps. Use UL Listed 24 VDC indicating
appliances only. Circuits are supervised and power-limited. See
Figure 23 for a list of recommended compatible indicating appliances.
Any or all of these circuits may be used as a releasing circuit by
programming it for RELEASE CKT. See the Releasing Applications
section of the IFC-200 Applications Technical Bulletin in this manual for
more information, including a list of compatible solenoid valves.
