DescriptionThe CN616 series has been discontinued. Please see the CN616A CN616A as a possible alternative or contact our Electronic Engineering department.
The CN616 Series is a highly versatile six-loop microprocessor-based controller designed for easy front panel or remote setup and operation. Each of six zones is sequentially scanned, and active zones are displayed. Individual zones can be locked for monitoring. Each instrument is programmable to meet operator needs for: Thermocouple Type, Temperature units Hi, Lo or Hi/Lo Alarm configured as Latching or Non-Latching and Autotune with Manual Trim or Manual PID Setting. The Zone Display Scan Time and Ramp/Soak can be set by the operator. Parameters and setpoints are retained when power is turned off. Password protection is provided to prevent accidental changes to calibration, PID setting and ramp/soak profile. If power loss occurs, the controller retains all the latest parameters and returns to “Run” mode.
All CN616 Series Controllers have RS-232 three-wire serial communications. Up to 10 units can be daisy-chained together. CN616-SOFT software is included with every unit at no charge. Windows 16/32 bit Operating Systems (Fully supported up to Windows XP)
Line Voltage is 120 Vac (110 vAC to 130 Vac)or 240 Vac (220 Vac to 260 Vac) selectable by external jumper assembly. Connections are made to the back of the instrument through easy-to-use screw terminal plugs.
The CN616 Series implements a security password to protect settings. The password can be enabled or disabled on the front panel and changed via RS-232. Calibration is performed on the front panel and is separately password protected. Higher level passwords are available.
The instrument is housed in a 1/4 DIN aluminum box which does not have to be removed for mounting. The unit mounts in a 1/4 DIN panel cutout and is secured by slide brackets. Control is done via 6 dc pulse outputs (one for each zone).
A single output relay is provided to indicate an alarm condition on any zone. The instrument shows an alarm condition by flashing the main temperature display while indicating the zone in alarm with a flashing zone number display. When set for Non-Latching, the alarm automatically resets when the condition changes. The alarm must be manually reset in the Latching setting.
The controller functions in two modes: “RUN” is the basic operating mode. “FUNCTION SELECT” is the password protected settings selection and control mode.
