MANUAL OVERRIDE BOARDS
MOB-4, MOB-8
DESCRIPTION
The MOB Series manual override boards are designed to
add hand/off/automatic operation to on/off controller outputs.
They may also be used as stand-alone override switch banks.
FEATURES
• AC or DC operation
• Ability to convert four or eight outputs to hand/off/auto
operation
• Wire-captive screw termination
• LED indication
• Feedback monitoring of switch positions
• Snap-track mounted
Hand/Off/Auto mode can be selected individually for each
channel (1-8 or 1-4) with a three-position toggle switch. Each
channel LED will light any time that output is commanded on
from the hand or auto mode.
24 VAC or VDC must be applied to the HOT and RETURN
terminals for the hand position to operate. The hand voltage
source (hot terminal) and each auto IN voltage source can be
separate sources as long as they all share a common return
connection.
The status contact is closed when all channel switches are
in the auto position. Moving any switch to the off or hand
position will cause the status contact to open.
Normally Closed to input of
monitoring computer
Contact opens if any switch
is not in AUTO position.
