Swastik GR818-A PID/On-Off Temperature Controllers


GR818-A PID/On-Off Temperature Controllers offer advanced temperature control capabilities with a 4-digit/7-segment display, providing precise monitoring and adjustment. With selectable resolution settings of 1 Degree C or 0.1 Degree C, it ensures accurate temperature management for various applications.

Featuring an impressive accuracy of +/- 0.5% FS, the controllers guarantee reliable and consistent performance. They operate within a voltage range of 85-265 VAC, accommodating diverse power supply conditions. The control output options include Relay/SSR and Analog (mA/mV), enabling flexible integration with different systems.

The GR818-A controllers support various input types, including Thermocouple, Voltage (mV), RTD, and Current (mA), ensuring compatibility with a wide range of temperature sensors. The PID/On-Off control types offer precise and responsive temperature regulation.

Constructed with an ABS plastic body in a sleek black color, the controllers are not only functional but also visually appealing. The model number GR818-AT 1220 represents the specific configuration, and the automatic type caters to efficient temperature control. With a current capacity of 100A, they are branded by Cautoni-Beeco Electronics, promising reliable performance for temperature-sensitive processes.
