It accepts 4-20 mA analog inputs, and all models feature a field-configurable BACnet\u00ae or Modbus\u00ae output for communication with a controller or building management system.<\/p>\n<p>Sensor configurations include combinations of internal and\/or remote sensors, including 3 remote sensors or 1 internal sensor + 2 remote sensors. Plug &amp; Play Smart Sensor technology simplifies and accelerates the replacement of pre-calibrated sensors.<\/p>\n<p>Standard features include two high-voltage SPDT dry contact relays with field-configurable time delays and trip levels, a horn and strobe connection, a field-selectable internal audible alarm, an LCD display with LED indicators for alarm status and channel faults, and an intuitive password-protected menu. Enhanced logic control with 8 priorities\/zonings provides extensive configuration and operational flexibility.<\/p>\n<p>Specialized options include two 4-20 mA outputs suitable for VFD control, relative humidity and temperature monitoring, low-temperature operation, a side-mounted strobe, an extra-loud or sealed side-mounted buzzer, and splash protection. The DV option upgrades the standard model to support dual-voltage inputs by adding a line-voltage function.<\/p>\n<h4>Key Features<\/h4>\n<ul>\n<li>Up to 3 gas channels with flexible internal and\/or remote sensor configurations<\/li>\n<li>Smart Plug &amp; Play Probe Pre-calibrated Play, end-of-life replacement available<\/li>\n<li>2 x 16-character LCD display with LED indicators<\/li>\n<li>Easy-access pushbuttons on the front of the enclosure for configuration and calibration<\/li>\n<li>24 VDC or VAC (ground reference) power supply, supports dual-voltage inputs via the DV option: line voltage<\/li>\n<li>Field-configurable BACnet\u00ae MS\/TP RS-485 or Modbus\u00ae RTU RS-485 digital output to the controller or energy management system<\/li>\n<li>User-selectable 4-20 mA, 0-10 V, or 2-10 V outputs (optional)<\/li>\n<li>Two SPDT dry contact relays rated at 5 A at 240 VAC<\/li>\n<li>USB port for configuration changes and system upgrades Firmware<\/li>\n<li>Standard waterproof and dustproof, corrosion-resistant (drip-proof) enclosure; IP54 rating with optional splash guard<\/li>\n<li>Optional Low Temperature Operation Package<\/li>\n<li>Optional Relative Humidity and Temperature Sensor<\/li>\n<li>Optional Side Strobe<\/li>\n<li>Optional Factory-Installed Splash Guard<\/li>\n<li>Optional Extra-Loud or Waterproof Side Horn<\/li>\n<li>Sensor Calibration Expansion Firmware (SCEF) for Parking Garage Applications<\/li>\n<li>RoHS Compliant PCBs<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<h2>cGas-SC<\/h2>\n<p>A standalone controller with up to 3 gas channels, plug-and-play smart sensor technology, and configurable control logic and priority settings.<\/p>\n","protected":false},"featured_media":14417,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1354,1372,1259,1260,1378,2289,1258,1477,1371,1262,1375,1263,1376,1374,1373,1264,1379,1357,1261,53],"product_tag":[2177,2176],"class_list":{"0":"post-14427","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-4-gas","7":"product_cat-cl2","8":"product_cat-co-en","9":"product_cat-co2-en","10":"product_cat-eto-en","11":"product_cat-fixed-mount-en","12":"product_cat-gas","13":"product_cat-gas-detectors","14":"product_cat-h2","15":"product_cat-h2s-en","16":"product_cat-hcn","17":"product_cat-lel","18":"product_cat-nh3-en","19":"product_cat-no","20":"product_cat-no2-en","21":"product_cat-o2-en","22":"product_cat-o3","23":"product_cat-so2","24":"product_cat-voc","25":"product_cat-automation","26":"product_tag-gas-detection-system","27":"product_tag-self-contained-controller","29":"first","30":"instock","31":"shipping-taxable","32":"product-type-simple"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.8 -
