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

4.4.3.2

Relay output interface card (OPC-RY)

The relay output interface card OPC-RY converts general-purpose output signals issued via inverter
terminals [Y1] and [Y2] or [Y3] and [Y4] to a relay output (one transfer contact). It has two
independent transfer contacts so that using two cards allows the user to activate up to four contact
outputs (Y1 to Y4).
A signal to be output to each contact can be defined with function codes E20 to E23. Selecting "Active
OFF" for a contact output with the function code enables the contact to be turned ON without relay coil
excitation. This is useful for a fail-safe application for the power system.
Ports available for the interface card and functionality assignments
A FRENIC-HVAC inverter has three option connection ports. Note that each port has some limitations
as shown below.

Name
Relay contacts to output signals selected by function
codes E20 and E22, such as Inverter Running, Frequency
Arrival and Overload Early Warning.
In "active ON", the contact [1A] – [1C] closes and [1B] –
[1C] opens while the signal is active.

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.
