These controllers and limits are available in a broad range of packaging options, allowing users to select the best version for their individual application. The controllers and limits are available with or without an operator interface and can be ordered in a 1/8 DIN square panel mount, DIN-rail mount or open-board design configurations. The basic and limit design provides significant improvements in the performance, repeatability and accuracy offered by analog basic temperature and limit controllers. The variable options for the SERIES CV (controller) and SERIES LV (limit) include an operator interface for viewing and selecting the set point. A red, four-character, seven segment LED displays the set point to show the process option. The set point selection is made with a continuous turn rotary encoder, or with discrete up/down cursor keys. Operating range temperature values are customer definable in the product configuration part number. The fixed options for the SERIES CF (controller) and SERIES LF (limit) offer fixed set points and are supplied without an operator interface. Operating set point temperature values are customer definable in the product configuration part number. The SERIES TM temperature indicator is available as an additional order option. These basic and limit controllers are UL® recognized and include CE approvals. The limit controllers are FM approved with special UL® approval for the open-board potted versions. CV and LV panel mount controllers ordered with discrete up/down cursor keys include NEMA 4X/IP65 seal protection.
