Sensor Communication - Z-Gard C Controller accepts 4-20 mA. Z-Gard C486 and CX II Controllers accept RS-485 from remote Z-Gard sensors. The controller automatically detects attached sensors and determines their full-scale value. Set points and readout displays are automatically adjusted to match the sensor
operating range.
Outputs - A variety of output options are available to integrate with common commercial equipment, including PLCs or building automation systems. Controllers include audible and visual LED alarm status indication. A wide variety of relay configurations are available for warning, alarm, and sensor fail. All Z-Gard Controllers incorporate a digital readout to display the active channel’s corresponding gas valve.

For wide-ranging gas-monitoring needs, the economical Z-Gard C 485 Controllers are up to the task. The controllers connect with a wide array of MSA Z-Gard S Sensors, with controller models accepting up to 24 sensors. Relay outputs indicate warning, alarm or sensor fail for each zone, and units are available with one or two zones. A large LED readout displays the active channel and the corresponding sensor gas level

The robust Z-Gard CXII Controller connects with a wide array of MSA Z-Gard Sensors, accepting up to 99 sensors. A large backlit LCD screen displays operating, alarm and fault diagnostic system status. Modbus RTU or BacNet MS/TP digital protocols are available for integration with building automation systems.

For general industry and HVAC applications, Z-Gard C Controllers simply get the job done. The controllers connect with a wide array of MSA Z-Gard S Sensors, with controller models accepting up to eight sensors. Relay outputs indicate warning levels and alarms for sensors, while a large LED readout displays the active channel and corresponding sensor gas level.
