(Temecula, CA) — Opto 22 has announced the release of the SNAP-PAC-SB1 and SNAP-PAC-SB2. These two new serial-based I/O processors (or “brains”) are used for serial I/O networking and performing local control for the company’s SNAP I/O, part of the award-winning SNAP PAC System of software, controllers, brains, and I/O.
The SNAP-PAC-SB1 and SNAP-PAC-SB2 serial brains offer an RS-485 serial interface between SNAP PAC System programmable automation controllers (PACs) and analog, digital, serial, and special purpose SNAP I/O modules. These new serial brains can coexist with Ethernet-based brains in a SNAP PAC System, offering more options for I/O network design without impacting control strategy design.
When used with the jointly released PAC Project 8.1, these serial brains enable a distributed control architecture–unique to Opto 22 SNAP PAC systems–where control functions are distributed to and executed at the I/O level. These functions include PID loop control, analog scaling, thermocouple linearization, digital counting and latching, analog clamping, alarming, event reactions, waveform generation, ramping, pulse generation, and totalization.
The SNAP-PAC-SB1 brain offloads tasks from a host PAC controller like counting, quadrature input, pulsing, and latching through custom application specific integrated circuits (ASICs), making it ideal for projects that include high-speed sequential logic, motion control, and robotics. The SNAP-PAC-SB2 offers software-based counting and latching. Both brains can address a mix of up to 512 points of analog, digital, serial, and special-purpose I/O on a single rack.
