Descrição
The CN1602 is a new line of limit controllers designed to provide a programmable safety cutout and optional alarm for use in a wide variety of applications. Packaged in 1/16 DIN, the CN1602 provides a latched relay output which is activated when process parameters either exceed or fall below the desired value, providing a fail safe shutoff which has to be manually reset before the process can continue. The instrument can be configured to be either a high limit unit where the relay will de-energize when the Process Variable (PV) is above the limit point setpoint, or a low limit where the relay will drop out when the PV falls below the setpoint. LED indication shows when limits have been exceeded and when the relay is latched out. It offers a full range of universal sensor input options, versatile configuration and a front panel sealed to NEMA-4 type/IP65. The CN1602 provides a valuable safety control element in most applications and systems.
