The expansion module outputs are relay contacts that may be individually configured for
normally open or normally closed contact position. Contact configuration is via circuit board
mounted jumper pins and clips. Refer to FIGURE #18 for jumper pin location and configuration
settings. Each output contact is rated maximum 0.5A 120VAC, 1.0A 30Vdc resistive.
Each expansion module also provides one programmable contact for desired control function.
Refer to Section 9.2
of this manual for programming functions and procedures for the
programmable contact feature.
Note: The communication cable between the MEC 2 and the expansion module must be
ordered separately.
