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 12 for the location of the IB2 Board and its connectors. Refer to Table 1 and
Table 2 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
assembly partially out of the shelf.
NOTE!
Two sets of Alarm Cables are available (see SAG582136800 for part numbers). One set for the Digital
Inputs and another set for the Relay Outputs. Refer to
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.
CAUTION! All conductors in this harness 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. The other piece contains the Temperature Probe and a
mating connector.
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 12 for the location of the IB2 Board and its connectors.
Refer to Table 1 and Table 2 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 negative signal and the opposite polarity return path). Observe proper polarity. Refer to Figure 12 for the
location of the IB2 Board and its connectors. Refer to Table 1 for pin-out information. Note that some of these
inputs are factory connected, as listed in Table 1.
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.
