SR107AD, SR108AD and SR109AD R C US Conforms to EN60204-1, EN954-1, EN292, VDE 0113-1 UL and C-UL listed, BG approved safety monitoring relays H SR107AD, SR108AD and SR109AD Dual Channel Safety Monitoring Relay ■ ■ ■ Power requirements—the SR107AD, SR108AD and SR109AD will accept 24 VAC/DC Inputs—the SR107AD, SR108AD and SR109AD will accept single or dual N/C inputs or dual PNP solid-state inputs from a light curtain (see SR102AM for application wiring for a light curtain) Outputs—the SR107AD, SR108AD and SR109AD have a total of 4 N/O outputs with 3, 2 or 1 of the outputs with a time delay of 1-30 sec. ■ ■ External Device Monitoring (EDM) is provided with a N/C loop between S12 and S21 on the SR107AD, SR108AD and SR109AD Reset mode—a monitored manual start or an auto/manual start may be configured with the SR107AD, SR108AD and SR109AD. Monitored manual reset requires closure of the reset circuit followed by opening of the circuit. Reset occurs when circuit is opened. Auto reset requires only closure of the reset circuit as reset occurs when circuit is closed. ■ PLC Compatible—The N/O off delayed outputs make it possible to use the SR107AD, SR108AD and SR109AD on machines with Programmable Logic Controllers that require some time to execute an orderly shutdown A Go to the Engineering Guide For in-depth information on safety standards and use.
