.jpg) | Series AN2 - Indicating Alarm Annunciator Up to 8 Inputs, Integral Power Supply The Series AN2 Indicating Alarm Annunciator provides visible and audible alarms for up to eight inputs. The annunciator also has two SPDT relay outputs that can be used to initiate external alarms, buzzers, or paging devices. The Integral 24 VDC power supply can power most level, temperature, pressure, and flow switches. Audible alarm conditions can be acknowledged, reset, or silenced either via the front panel push buttons or the rear terminal block. The Series AN2 can be set to any common ISA sequences including First-Out.  | ||||||||
.jpg) | Series SC1290/SC1490 - Thermocouple & RTD Limit/Alarm Switch Module Two Form C (SPDT) Switches, Small Size, Mounts Easily on 35 mm DIN Rail The Series SC1290 & SC1490 Thermocouple Limit/Alarm Switch Modules are on-off or limit switches with selectable process signal, thermocouple, or RTD inputs. Input type, scale range, output action, and output type are all selectable by the user in the field. All selections are made through easily accessible switches without the need to open the product. Each unit has two form C (SPDT) relays which can operate independently, or be logically connected to operate as a DPDT output. A two color LED indicator indicates the status of each output relay. These units mount easily on a standard 35 mm DIN rail. Low Voltage (SCLXXXX) units are also available. | ||||||||

.jpg) | Series 1000 - Process Indicator and Alarm Low cost 1/16 DIN units provide 3-1/2 digit, 0.3" high LED readings from four field selectable input ranges. Includes integral power supply to operate 2-wire transmitters. Optional low/high SPST alarm relays can be set for direct or reverse action. 1.88" H x 1.88" W x 5.05" D (48 x 48 x 128 mm). | ||||||||
.jpg) | Series HFO - In-Line Flow Alarm Latching Alarm Capabilities, For Air, Water or Caustic Fluids, Unrestricted Mounting The Series HFO Flow Alarm provides continuous monitoring and control of flow rate levels. The flow alarm can be configured to open or close a contact for an increasing or decreasing set point. The unit includes two 10A SPDT limit switches with field adjustable alarm settings. Integral direct reading scale provides local indication of flow rate. The flow alarm is designed to mount in any orientation and does not require inlet or outlet straight plumbing. The Series HFO is constructed with a rugged cast aluminum NEMA 4X (IP65) enclosure for installation outdoors or in harsh environments. | ||||||||
