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. |
