•
The 9950-10/11 will support up to eight (8) relays, though only four actually
fi
t directly inside its compact ¼ DIN enclosure.
8059 External Relay Modules of four relays may be connected to the 9950 via digital (S³L) at the I/O Module (this does NOT-
consume a sensor input channel).
•
External relays are completely independent of internal relays, so it is not necessary to install an internal relay module into the
9950 to use the external relays. In the 9950 menus, external relays will always be identi
fi
ed as Relays A, B, C, and D.
•
Digital (S³L) pass-thru terminals on the 8059 can help to reduce sensor wiring congestion at the 9950.
See the 8059 instruction manual for details.
•
External Relays mount on DIN rail inside a panel and can be tested remotely from the 9950, or locally with switches built-in for
convenience. They also include LED relay status indicators, but the status of these and all relays is available at all times in a
single screen in the 9950 View mode.
•
Any and all relays are freely assignable to any channel. Hysteresis and time delay are adjustable for each relay.
•
It is perfectly acceptable to mix and match relay types between internal and external modules.
However, NOTE: The 9950 only allows external relays to be used in modes Off, Low, Hi, Window, Total, and Error.
•
8059 External Relay Modules contain dry-contact relays only. These electromechanical switches are suitable for many general-
purpose applications, AC or DC, including AC loads up to 250 V.
•
Switching active loads (most commonly inductive) can cause contact arcing suf
fi
cient to damage relays. The RC Filter Kit or
“snubber” is available as an accessory to reduce or eliminate these damaging effects.
