7-3-9. Operating Rate Output : TCB-PCIN4UL
<Electrical Rating>
208-230 VAC, 10 mA or more, 1A or less
24 VDC, 10 mA or more, 1 A or less (non-conductive load)
At the output terminals, a signal is present (relay closed) or absent (relay open) in various combinations
according to the system operation factor, as shown in the diagram.
(The operation rate (FA) is the percentage ratio of the current output of the system to the maximum output (100%).)
Note 1: Output Relay (K1, K2, K3) Contact Specifications
• Output terminals (OUTPUT1, 2, 3) must satisfy the following electrical rating.
• When connecting a conductive load (e.g. relay coil) to loads K1, K2 and K3, insert a surge killer CR (for an AC
power supply) or a diode for preventing back electromotive force (for a DC power supply) on the bypass circuit.
