Timer - Delay-on-Break
TRB Series
Features:
The TRB Series combines an isolated, 10A
electromechanical relay output with analog timing
circuitry. False trigger of the TRB by a transient is
unlikely because of the complete isolation of the
circuit from the line prior to initiation. The initiate
contact is common to one side of the line and may
be utilized to operate other loads. Installation is
easy due to the TRB’s industry standard 8 or 11-pin
plug-in base wiring.
Connection:
8-pin octal SPDT
• Onboard adjustable time delays
• Fixed or adjustable delays from 0.05 - 600s in
multiple ranges
• ±2% repeat accuracy
• AC and DC operating voltages are available
• Isolated, 10A, SPDT or DPDT output contacts
Approvals:
8-pin models UL listed
when used in combination
with P1011-6 socket only.
Operation (Delay-on-Break):
Input voltage must be applied before and during timing.
Upon closure of the initiate switch, the output relay
energizes. The time delay begins when the initiate switch
is opened (trailing edge triggered). The output remains
energized during timing. At the end of the time delay,
the output de-energizes. The output will energize if the
initiate switch is closed when input voltage is applied.
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the time delay
and output .
