H34 Series

Temperature and Process Controllers

The H34-540 Series is 1/16 DIN or 1/4 DIN temperature controller with auto tuning PID control capabilities. One of four user programmable set points may be selected. For PID control in the form of time proportional relay on/off output, time proportional voltage pulse, or 4-20 mAmp signal control. Its universal input accepts 23 inputs varieties, including thermocouple, RTD, and voltage inputs can be easily configured for a 4-20 mAmp input. The relays may be programmed as alarms with 20 different high, low, and deviation alarm types which can include fail-safe operation. Digital input options add the ability of external contacts to operate the controller. With RS-485 serial communication options include protocols for master/slave set point control, modbus ASCII and RTU.

The H34-550 Series is 1/16 DIN or 1/4 DIN ramp and soak controller with auto-tuning PID control capabilities. Two programs store 15 segments each for precision set point control. At the completion of a program, the controller can hold a set point, stop the outputs, or loop the completion of a program. Thus, enabling one 30 segment program to be used. Its universal ”nput accepts 23 inputs varieties, including hermocouple, RTD, and voltage inputs can easily be configured for a 4-20 mAmp input. The relays may be programmed as alarms with 20 different high, low, and deviation alarm types which include fail-safe operation. Digital input options add the ability of external contacts to operate the controller and digital output options are available. With RS-485 serial communication options include protocols for master/slave set point control, modbus ASCII and RTU.
