Features:
- Four-Channel Control Card (4-20mA Input)
- Card depending on the type of gas detector being fitted to the system
- The four-channel control card can control up to four gas detection loops
The 5704 four-channel control card provides control, display, and alarm functions for up to four connected gas detectors. A backlit front panel display shows gas readings, channel status, and channel number, while LED indicators show alarm status. Alarms can be reset via buttons, and the control card can also be used with engineering cards.
This microprocessor-controlled control card can be fully customized to various connected gas detectors and application requirements. Software configuration settings are stored in EEPROM. Optional analog output modules can be inserted into the four-channel control card for remote output of channel card readings. One module is required per channel, and different types of modules are provided, which can be used as current sources or current absorbers as needed.
The 05704-A-0145 Honeywell Four Channel Control Card may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Provides the voltage and current required to drive connected sensors. Processes input sensor signals. Displays signal levels one by one on the front panel LCD. Compares the signal level of each channel with predefined alarm limits. When a preset alarm limit is exceeded, an alarm is triggered: the front panel LED indicator illuminates and the connected relay operates. Sends alarm status information to other cards. Self-tests the operation of circuit components, software, and sensor status.
Industrial Gas Detection: Monitors harmful, flammable, or toxic gases (e.g., methane, carbon monoxide, or chlorine) in chemical plants, refineries, and manufacturing plants.
Safety Monitoring: Simultaneously processes signals from up to four field-mounted sensors to trigger multi-level alarms (A1, A2, A3) and protective relays.
System Integration: Connects remote sensor data to higher-level automation systems, such as PLCs (Programmable Logic Controllers) or DCSs (Distributed Control Systems), via isolated current outputs.
Environmental Monitoring: Used in municipal applications to monitor wastewater gases, landfill emissions, and indoor air quality.
