The SNAP-PAC-S1 programmable automation controller provides powerful, real-time control and communications to meet your industrial control, monitoring, and data acquisition needs.
One of the four components of the SNAP PAC System, the SNAP-PAC-S1 is fully integrated with PAC Project software, SNAP PAC brains, and SNAP I/O modules to form a complete control system. The SNAP PAC System includes digital and analog control, serial string handling, PID loops, and enterprise connectivity.
The controller is compact and industrially hardened. It includes two independent Ethernet network interfaces with separate IP addresses, which can be used to segment the control network from the company network or for redundant Ethernet links.
The SNAP-PAC-S1 also has three serial ports: an RS-232 port with full hardware handshaking, ideal for PPP communication using a modem; another RS-232 port for connecting directly to serial devices; and an RS-485 port for connecting to SNAP PAC Serial brains or to legacy mistic I/O units.
