No Longer Available - For Reference Purposes Only RL-740 General Purpose Switching Relay Card FEATURES GENERAL • Suitable for general purpose switching and isolation. • Front panel LED status indicators. • TTL or direct relay switching. The RL-740 relay card is designed to interface with the IRT Eurocard VG-737 video and AG-738 audio program fail modules. Front panel LED indicators are used to indicate the status of each relay circuit. The RL-740 utility relay card is designed to provide two isolated contact sets and contains 5 DPST relays which can be controlled individually, both the make and break contacts are available either directly or by on board link selection. BLOCK DIAGRAM RL-740 SIGNAL PATH +12V Link RL1 Relay 1 Contacts Relay 1 One of the contact sets can also have the relay common contacts bussed to facilitate connection to the input circuit of the IRT 5x1 video and audio switchers. Relay 1 Control +12V Link Relay 5 RL5 Relay 5 Contacts Relay 5 Control Relay Commons When the relay is NOT ENERGISED relay 1 circuit switches input 1 to the output thus providing a secure path when power is not present on the module. The relays used are bifurcated contact low energising current relays designed for long life and high reliability. Note: For relay switching of video, data and HF, see the AVS-3170 relay switcher. See also other 3000 series switching products. Due to our policy of continuing development, these specifications are subject to change without notice.
