301-C

The Honeywell 301-C serves as a robust gas detection controller with a solid capability to monitor hazardous environments. This unit functions efficiently on a voltage rating of 17-27 VAC or 24-38 VDC, allowing for easy implementation in various systems. Designed with a weight of 2.4 lbs, this controller is compact yet capable of handling substantial operational demands.

Operating at a current rating of 500 mA, the 301-C is built to endure a temperature spectrum of -20°C to 50°C, facilitating stable performance in both cold and warm conditions. The humidity range supported extends from 0 to 95% relative humidity (non-condensing), which is crucial for versatility in different atmospheric conditions.

The gas detection controller features an extensive network capacity, allowing the integration of up to 96 transmitter inputs across 3 RS-485 channels. For communication, it utilizes a Modbus protocol with the optional BACnet/IP capability, catering to various system needs.

The 301-C also includes a 122 x 32 dot matrix LCD for clear display purposes. Users benefit from programming options for up to 126 distinct zones and 4 fully programmable alarm levels, which can be critical for tailored safety measures. The configuration includes time delays that can be adjusted to 0, 30 seconds, 45 seconds, or ranges of 1 to 99 minutes before and after alarms trigger.

The relay output supports a capacity of 5 A at 30 VDC or 250 VAC (for resistive loads) via four double-pole double-throw (DPDT) relays. Additionally, communication line length per channel can reach up to 2000 feet (609 meters), ensuring adequate signal transmission over long distances.
