T48/P48/TLA OUTPUT BOARD
INSTALLING AN OUTPUT BOARD
Caution: The bezel assembly contains electronic circuits that can be damaged by static electricity. Before removing the assembly, discharge static charge on
your body by touching an earth ground point. It is also important that the bezel assembly be handled only by the bezel itself. When handling a circuit board, be
certain that hands are free from dirt, oil, etc., to avoid circuit contamination that may lead to a malfunction.
1. Remove the controller from the case.
2. Lift up on the top bezel board latch while gently pulling out on the bezel/
display board assembly. Do NOT remove the display board from the
bezel.
3. Remove the output board by pulling it away from the other boards.
Replace the output board by aligning the board to board connector. Be
certain the connector is fully mated.
4. Connect the bezel/display board assembly by guiding the board ends into
the bezel latches. Slide the assembly on evenly until the display board
connector is completely engaged and bezel latches are fully seated onto
the boards.
Note: When replacing the output board, be certain to install a new output
board of the same type. Appropriate rewiring considerations must be given if
the output board type is changed.

SPECIFICATIONS & TYPICAL CONNECTIONS
Relay Connections
RBD48 Relay Outputs:
Type: Form-A (Shared common for the Alarms)
Contact Rating: 3 A @ 250 VAC or 30 VDC (resistive load)
RBDLA Relay Outputs:
Limit Relay Type: Form-C
Alarm 1 Relay Type: Form-A
Contact Rating: 5 A @ 250 VAC or 30 VDC (resistive load)
Life Expectancy: 100,000 cycles at max. load rating. (Decreasing load and/
or increasing cycle time, increases life expectancy.)
To prolong contact life and suppress electrical noise interference due to the
switching of inductive loads, it is good installation practice to install a snubber
across the contactor. Follow the manufacturer's instructions for installation.
Note: Snubber leakage current can cause some electromechanical devices to
be held ON.
