External Interface Connections
IB2 (Controller Interface Board) Connections
The IB2 (Controller Interface Board) provides connection points for digital inputs, programmable relay outputs,
and temperature probes. Refer to
Figure 13 for connector locations and to Table 1 , Table 2 , and Table 3 for
pin-out information.
If required to access these connection points, loosen the captive fastener on the front of the IB2 Board, and
slide the board partially out of the shelf.
NOTE!
Alarm Cables sets are available (see SAG582136700 for part numbers). Two sets are available
for the Digital Inputs and another set for the Relay Outputs. Refer to
Table 1
through
Table 3
for color
scheme. If the Relay Outputs Alarm Cable or Digital Inputs Alarm Cable is ordered, one half is factory
connected in the shelf. The other half has a mating connector on one end and is un-terminated on the
other end.
ALERT! All conductors in the Alarm Cable may be connected within the cabinet. Shorting or grounding
of unused conductors may result in service interruption or equipment damage. Therefore insulate all
conductor ends not being used in your application.
NOTE!
Each Temperature Probe assembly consists of two pieces. If probes are ordered with the Power
System, one piece is factory connected in the shelf.
Digital Inputs and Programmable Relay Outputs
Digital input and relay output leads are connected to screw-type terminal blocks located on the IB2.
Recommended torque for these connections is 2.2 in-lbs. Refer to
Figure 13 for connector locations, and to
Table 1 , Table 2 , and Table 3 for pin-out information.
Digital Inputs
Connect up to eight (8) digital inputs to the IB2. Note that you must supply both paths for the digital input
(either a positive or a negative signal and the opposite polarity return path). Observe proper polarity. Refer to
Figure 13 for terminal locations and Table 1 and Table 2 for pin-out information. Note that some of these
inputs are factory connected, as listed in Table 1 and Table 2 .
The digital inputs can be programmed to provide an alarm when the signal is applied (HIGH) or removed
(LOW). Refer to the Controller User Manual for programming information.
Digital Input Ratings: Refer to the following.
a) Maximum Voltage Rating: 60V DC.
b) Active High: > 19V DC.
c) Active Low: < 1V DC.
The digital inputs may be preprogrammed for specific functions. Refer to the configuration drawing (C-
drawing) supplied with your system for your system’s specific configuration.
External Battery Disconnect Circuit Breaker Alarm Input
Connect the alarm lead from an optional External Battery Disconnect Unit or the battery disconnect circuit
breaker on an optional Battery Tray to the Negative (–) side of Digital Input #2 (terminal 3 of connector J3). –
48VDC is applied to the alarm lead when the circuit breaker is in the OFF position. Refer to
Figure 13 .
