Thermocouple and RTD Iinput| Designed specifically for equipment manufacturers who demand tight process control, the 7SD, 7SM and 7SH offer outstanding performance and a variety of features in a cost effective 1/16 DIN package. NEMA 4X faceplates allow these units to be used in applications in which washdowns and dust conditions exist. Thermocouple or RTD input and a 3 digit display provide complete coverage for plastics, packaging, | food, environmental chambers and
other cost sensitive applications. The 7SD, 7SM and 7SH provide solutions for heating, heating plus alarm and heating/cooling applications. Alarms can be process, deviation or band type, direct or reverse, with manual reset. Easy to understand, set-up and use, these controllers provide exceptional value to the industrial user. |

Soft Start Setpoint A configurable threshold can be used to limit output power during initial startup (use this if the impedance of the heating load changes as the process temperature increases). |
Alarm Standby Alarm Standby can be used to mask alarm conditions if process low alarms are employed and the process has not yet reached the alarm threshold. |

Model 7SD - Deviation
Display |
Model 7SM - Dual Display The 7SM has all the features of the 7SD (except the bargraph display) but with a dual 3 digit, 7 segment display to show both process value and setpoint. Model 7SH - Heat/Cool The 7SH controller is a 7SM with heat/cool capability (OP2 relay=Cool). The relative cooling gain can be set from 1.0 to 0.2 (1x to 5x the heating proportional band). Configurable overlap and deadband allows customization of the 7SH for unique process heat/cool requirements. |
