Thermocouple and RTD Input| Designed specifically for equipment manufacturers who demand tight process control, the 7EM offers outstanding performance and a variety of features in an 1/8 DIN package. The cost effective 7EM is a configurable, Smart AT autotuning heat or heat/cool controller with thermocouple and RTD inputs. It is ideal for applications such as extrusion, food and environmental chambers in which the input range does not exceed 999. It has a bright dual display for process temperature and setpoint and 4 LED beacons for operating status. | The 7EM has 3 outputs. OP1 can be a time proportioned relay or SSR for heating. OP2 features a relay or SSR for time proportioned cooling or Alarm 2. OP3 is an optional relay Alarm 2. Alarms can be process, deviation or band type, direct or reverse, with automatic or manual reset, plus a unique optional heater breakdown alarm. The 7EM is available with a 100-240 Vac switching power supply or an optional 24 Vac/Vdc supply. Easy to understand, configure and use, the 7EM provides exceptional value to the industrial user. | ||
A Variety of Standard and Optional Features |
Heater Breakdown Detection |
||
| Among the 7EMÕs standard features are ramp to setpoint, soft start power limiting, sensor break protection, and a standby alarm sequence to mask alarm conditions until the PV reaches the low alarm threshold. There is also an Òoutput offÓ function which disables the control output, allowing the 7EM to operate as an indicator. The optional Heater Breakdown Detection feature allows measurement of the load by a current transformer, displaying the full scale load current and signaling an alarm condition to Alarm 2 when the current is below a programmed threshold. |
