The C64 is an ideal solution for monitoring up to 64 critical input variables.

Built around ‘plug and play’ input and output modules, the C64 Protector controller can accept signals from wireless monitors, analog sensors, digital sensors, discrete inputs or even direct connection to bridge-style combustible or VOC sensors.

Built-in user-prompted calibration mode, three programmable alarm levels per channel, five standard relays (A1, A2, A3, FAULT and HORN), dual RS-485 serial interfaces and wired Ethernet are included in the base configuration. Up to sixty-four 4-20mA analog outputs, 256 discrete relays and wireless radio modems are available as options.

The high resolution color LCD displays data as trends, bargraphs and calibrated engineering units; a 24-hour trend graph for each channel is always available. In addition to touch-sensitive buttons, a standard magnetic keypad allows non-intrusive operation in potentially hazardous locations.

The C64 Protector controller supports up to four RS-485 serial MODBUS interfaces for maximum flexibility. Available data logging using SD memory cards combines control and data archive functionality in a single package. Configuration data can also be programmed and downloaded using the intergrated SD card slot.

Built-in support for GDS Corp GASMAX IIx and ECx wireless gas monitors makes it easy to install and manage a wireless system. Using GDS Corp’s ProtectorView software and the built-in interface, a remote display of the controller’s realtime status and stored configuration is available across any Ethernet network.

The C64 Protector is designed from the ground up for critical alarm monitoring. In addition to gas detection, the controller is idealy suited for flow measurement, tank level monitoring and other critical alarm applications.

The C64 Protector is available in panel mount, single or dual rack mount, NEMA 4X fiberglass and stainless steel, and NEMA 7 explosion proof enclosures.
