Model 720RB/720RBDIN is a legacy product and is not recommended for new designs. Some of legacy products may be available but may have significant lead times and minimum order requirements. For new designs, use our Product Finder to find a comparable product or contact our Design Support Team.

Description

The Sensoray Model 720RB Solid State Relay board provides optically coupled interfaces between low-level computer signals and high-power loads. Isolation is achieved by adding opto-coupled solid state relay modules. Up to twenty-four solid state releys may be added to the board.

Field connections

Two screw terminals are available for each of the twenty-four loads. The terminals will accept 16 to 24 AWG stripped wire.

Computer connections

Low-level signals from parallel adapters such as Sensoray's 7421 are connected to the 720RB with either an 80-conductor round cable or 50-conductor flat cable. The 50-conductor cable follows industry-standard pinouts for solid state relay boards. The 80-conductor cable brings 72 I/O signals from high capacity I/O adapters to one 720RB. Forty-eight of these signals may be diverted to two additional 720RB's so that 72 solid state relays may be controlled from a single adapter.

Mounting hardware

The standard 720RB is supplied with eight half-inch high threaded standoffs. Model 720RBDIN is supplied with mounting hardware for DIN rails.
