SNAP 2-Wire/4-Wire Serial Communication Module Opto 22 SNAP-SCM-485-422 2-Channel
Opto 22 SNAP-SCM-485-422 - SNAP 2-Wire/4-Wire Serial Communication Module, 2-Channel: Io Modules: Industrial & Scientific. Opto 22 SNAP-SCM-485-422 - SNAP 2-Wire/4-Wire Serial Communication Module, 2-Channel: Io Modules: Industrial & Scientific. The SNAP-SCM-485-422 provides two 2-wire RS-485 serial communication ports for two channels of high-speed, isolated serial data, or one 4-wire serial communication port for a single channel. Used with a brain or R-series controller, the module connects serial devices such as printers, scales, chart recorders, and barcode systems to an Ethernet network for control, monitoring, or data acquisition. Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-based control or for use as intelligent remote I/O for an Allen-Bradley PLC system. NOTE: The SNAP-SCM-485-422 is also compatible with SNAP Ethernet, SNAP Simple, and SNAP Ultimate brains.Factory Mutual, Canadian Factory Mutual, IEC 950: 1991-09, 89/6/EEC, 2002/95/EC, Defense Federal Acquisition Regulation Supplement . . .
