External Relay Setup:
The Relay module is offered with three types of relays, mechanical and solid state (AC
or DC). The mechanical relay’s output consists of terminal 4 - common (COM), terminal
3 - normally open (NO), and terminal 2 - normally closed (NC) (see FIG 22). The
mechanical relay (OMRON G2R-1-SN) is rated for a maximum of 10A @250VAC or 10A
@30VDC. Relay drive current for mechanical relay is 70mA @ 5VDC. The solid state
relay’s output consists of terminals 3 and 4 - normally open (NO). The solid state relay
(OMRON G3R-OA202-SZN / G3R-ODX02SN-DC524) is rated for a maximum of 2A
@100-240VAC / 2A @5-48VDC. Relay drive current for solid state relay is 11mA @
5VDC. The relay control is described in Parameter Setup Section. Table 14 lists the
scale signal cable wire color control for each relay module.
