Figure 1-2. CEM-2020H Overall Dimensions 

Connections 

Contact Expansion Module connections are dependent on the application. Incorrect wiring may result in 

damage to the module. 

 

Note 

Operating power from the battery must be of the correct polarity. 

Although reverse polarity will not cause damage, the CEM-2020 will 

not operate. 
Be sure that the CEM-2020 is hard-wired to earth ground with no 

smaller than 12 AWG copper wire attached to the chassis ground 

terminal on the module. 

Terminations 

The terminal interface consists of plug-in connectors with screw-down compression terminals. 
CEM-2020 connections are made with one 5-position connector, two 18-position connectors, and two 24-

position connectors with screw-down compression terminals. These connectors plug into headers on the 

CEM-2020. The connectors and headers have dovetailed edges that ensure proper connector orientation. 

The connectors and headers are uniquely keyed to ensure that the connectors mate only with the correct 

headers. Connector screw terminals accept a maximum wire size of 12 AWG (3.31 mm

2

). Maximum 

screw torque is 5 inch-pounds (0.56 N

•

m). 

Operating Power 

The Contact Expansion Module operating power input accepts either 12 Vdc or 24 Vdc and tolerates 

voltage over the range of 6 to 32 Vdc. Operating power must be of the correct polarity. Although reverse
