Relay Output Interface Card (Opc-Ry2) - Fuji Electric FRENIC-HVAC User Manual

4.4.3.3

Relay output interface card (OPC-RY2)

The relay output interface card OPC-RY2 adds seven independent transfer contacts (1A contact) to the
inverter. Using this card under cascade control enables the inverter to control seven motors. (Using
also two transfer contacts on the inverter unit makes it possible to control a maximum of eight motors
plus one (auxiliary pump) under cascade control.)
Ports available for the interface card
This interface card can be connected to either one of the B- and C-ports, out of three option connection
ports (A-, B-, and C-ports) provided on the FRENIC-HVAC. Two or more relay output interface cards
cannot be connected at a time.

Name
These relay contacts output various signals ("Inverter
running," "Frequency arrival signal," "Motor overload early
warning," etc.) selected with Function codes o01 to o07.
When [nA-nC] is short-circuited (active ON), the output
signal is Active. Where, n = one of 6 to 12.
250 VAC, 0.3A, cosΦ = 0.3, or 48 VDC, 0.5A (resistor load)
200,000 times (ON/OFF every 1 second) at 250 VAC, 0.3A
200,000 times (ON/OFF every 1 second) at 48 VDC, 0.5A
Note: When frequent ON/OFF switching is anticipated (for example,
when using the current limit function with the inverter output limiting
signal), use the terminals [Y1] to [Y4] (transistor outputs) instead.
