9.10 Setting Digital I/O Module Jumpers

9.10.1 Disassembly of the P30A Module

To set the jumpers on either board of the Digital I/O Module, the boards must first be
separated:
1. Remove the three screws as shown:
2. Gently pull apart the boards by the inter-board connector near the back of the
module.
Reassembly is performed in the reverse order.

9.10.2 Disassembly of the P31 Module

1. Remove the six screws (three per side) indicated in Figure 13, and set aside the
shields labeled PCB 712. Identify the main circuit boards that comprise the P31
assembly. They are labeled 693, 692, and 716.
a. PCB 693 contains:
 Terminal block for I/O points 1-8 (pins labeled 1-16 in blue).
 Range jumpers for input points 1-8.
 Normally open/normally closed jumpers for output points 1-4.
b. PCB 692 contains:
 Power-up condition jumpers for output points 1-4.
c. PCB 716 contains:
 Terminal block for I/O points 9-16 (pins labeled 17-32 in red).
 Range jumpers for input points 9-16.
2. Note: If you only need access to the jumpers for configuring the digital output
