IV. Conversion Module Wiring Diagram
The following diagram shows the connections from the existing B814-108 and B840-108 swing-arm, through the conver-
sion module, 1492 cable and to the 1756-OX8I output module. The diagrams can be used as an aid in possible system
troubleshooting.

Conversion Module Installation and Application Considerations

The B814-108 relay module resistive current limits versus 1756-OX8I limits are as follows: (NOTE: for switching and inductive
current and voltage ratings, refer to the modules Installation Manual)
B814-108 1756-OX8I w/ 1492-CABLE003Y
a) Current/Point 3A Cont, 2A Switching 960VA or 150W DC 2A @ 30V DC/125V AC
 The B814-108 is fused per output point. The 1756-OX8I is NOT fused. The 1492-CM800-LD015 provides a 5x20mm fuse
per 1756-OX8I point. Fuse rating for this configuration is 2 Amps.
 The 1492-CABLE003Y current is limited to 2A per pin.
 The B814-108 allowed using a circuit board jumper to configure each relay output for N.O. or N.C. operation (N.O. default),
but only one set of field terminals was provided on the module. The 1492-CM800-LD015 conversion module is set for N.O.
relay operation. If the N.C. contact of the 1756-OX8I relay module is required, it may be accessed by modifying the wiring at
the module’s swing-arm (terminal block).
 Refer to your B814-108 and 1756-OXI Installation Manual wiring schematics and diagrams. Ensure 1756 output module
ratings are not exceeded.

There are several key application considerations and system specifications (bottom of drawing) when
using these components (conversion module, cable and output module). Read and understand these
considerations before installation. In addition, refer to the current draw requirements of the existing
loads for this configuration to ensure they are within the current ratings of the 1756 output module. WARNING
