RKI AC-7412 Wired Gas Controller

The RKI AC-7412 is a 12-channel wired gas monitoring controller that accepts any 4-20mA sensor input, giving facilities a flexible hub for wired detector networks without the channel count of RKI's larger 32/64-channel systems. A 160x104 transflective graphical LCD with LED backlighting shows all channels at a glance, and four dry-contact relays (4A fuses, latching or non-latching) drive alarms and control outputs. RS-485 Modbus output integrates the controller into a facility's SCADA or building management system, and the NEMA-4X fiberglass enclosure is rated for outdoor use from -40°F to 158°F. Power is 12-35VDC standard, with an optional AC supply for facilities without existing low-voltage DC infrastructure.
